HELP! My Honda is Stuck in PARK! (Russian Hack Repair)

Uh oh, this 2003 Honda Accord is immobilized because it refuses to shift out of park!
The diagnosis shows an unexpected culprit which would be quite expensive to repair.
However, with a bit of creativity we get the Accord back on the road :)

[@PatGreen1830]

I enjoy watching you troubleshoot all the various options. Sometimes I think that is a more valuable lesson for all of us watching. Thank you.

[@TheOmegaman69]

I think you might want to check into the TP sensor. The TP Sensor voltage, KOEO (or idle), should be 0.49 Volts DC. The relative throttle position should be 0%. The relative throttle position is what is used, I believe, by the ECM for this shift interlock circuit. If it is above 0%, the shifter will not move out of park. I believe there maybe a TSB or recall on this issue. If the "TP sensor" PID you were looking at is the relative TP sensor value, then it should be 0%, and not 9.80%. This is just a possibility and a guess, so please keep that in mind. I am pretty sure that it is the relative throttle position sensor value that is used, not the actual value, by the ECM for this shift interlock circuit, and it must be 0% or it will not shift out of park. Again, just a possibility and a guess. I don't have enough specific information in this case to be able to do much more than suggest a possibility and provide a guess. Just wanted to add it would be helpful to ask if the TPS Sensor (Throttle Body) has been replaced recently. If so, then the ECM needs to be reset and a idle relearn done, which should put the relative TP sensor to 0%. The relative throttle position sensor value is a learned value.

Yes. The positive side from the ignitionswitch an negative side over a relay from the brakeswitch. Simple and oldschool. No computer needed... ;) Addendum: After thinking a little about... I would add a second relay steared by the P/N contact to provide the ignition positive for the lock. So the lock will only energized when its necessary. This prevents it from overheat during long breaksessions while driving or just stop&go on traficjam ;)

60 Minutes aired a report titled "Out of Control" on November 23, 1986. Almost killed the Audi brand. That's where we got the shift interlock from. BTW: "Subsequent investigation revealed that 60 Minutes had not disclosed they had engineered the vehicle's behavior - fitting a canister of compressed air on the passenger-side floor, linked via a hose to a hole drilled into the transmission."

this is a fix I would do on my OWN car as I'm not going to sue myself. Ivan, as pointed out in some of the other comments, you gotta be careful with stuff like this. I know YOU KNOW but you're such a great guy and very talented and conscientious - I'd hate to see you in a situation where some lawyer tears you to shreds on a liability claim. There HAS to be a way to wire in a relay off that brake pedal switch. Pull the ground signal off that and send it to the solenoid. You could DEFINITELY come up with something. That 'fix' is ok short term but I'd get that car back in your shop and do the 'relay workaround' . Your videos are awesome- I've learned so much- thank you for doing these.

I had the same thought too as the pin on the bcm will not change even if the solonid side is grounded as it actavates a relay not feeds the solonid. Also you read that throttle must not be pressed while looking up how the solonid functions. Although some electronic tbs dont have a idle bypass and 10% would make sense possibly not raising a red flag.

[@stevo3644]

Great video and thanks for sharing 👍I have a friend with one of these vehicles and it is having a similar issue. A lot of the comments in this thread recommend the use of relays which makes sense as another solution. After some thought I have come up with a way to use the park switch wire and also the brake switch as triggers for the relays. You will need 2 x four pin relays for this to work. On relay no 1 have the brake wire feed wire going to pin 86. Wire pin 85 and 30 to earth. Pin 87 is now a negative output when the brake switch is activated. On relay no 2 use the negative output from relay no 1 to pin 86. Feed wire from park switch to pin 85, pin 30 a fused power feed and pin 87 output to the lock out solenoid.

Ivan, love your diagnostic videos! On this one, the root cause is very probably related to the TPS. You seemed to get locked in on the brake application, but I strongly suspect that the issue is that the driver is interpreting that the throttle is being depressed and thus not energizing the solenoid to allow shift out of Park. Could be that the throttle got excessive carbon build up, was serviced/cleaned, or the TPS was replaced. I would have tried a Throttle Body relearn/reset -- I bet that would clear up the problem without bypassing this safety-related mechanism that avoids inadvertent shifts out of park. If you don't have the tool to reset the throttle body, you can try the following:

Great fix Ivan! I would certainly do that on my car or on a friend or family member's car, but I would personally be very hesitant to bypass any safety feature on a customer's car for liability as a lot of people are irresponsible and happy to sue. My concern would be a situation such as customer leaves kid in running car while going into gas station, kid puts car into gear and it runs into someone or something and causes serious injury or expensive damage, and customer sues mechanic for trying to help them and wins. Obviously not a terribly likely scenario, but I have heard of things like that happening and it's definitely something to keep in mind.

No way would I modify a safety feature on a car. Since you offer automotive repair services, you are considered a professional, legally speaking. Even if the owner is aware and agrees with what you did, if they loan the car to someone else or sell the car, and some kind of accident happens.... Well, that opens you up to a whole lot of liability issues. I'm not a lawyer, and this is not legal advice, but my son just graduated law school and we discuss a lot of cases in the news and law theory. I'm telling all mechanics out there, DON'T modify a safety system on a car.

Is 9.80% normal for the TPS at rest for this model of car? Just typing aloud as I don't know the answer to that question. Maybe the PCM is not firing the shift interlock because it thinks 9.80% TPS is not the resting point(?) and as you point out TPS position is a criteria here. And following from that - is a TPS relearn possible?

[@inothome]

Agreed, what is the threshold the PCM is using to determine off throttle?

[@ecaparts]

Yes correct. I found a TSB for 03-04 Accords where the shifter is stuck in park after throttle body replacement. You have to do a throttle relearn for the PCM to allow the shift lock solenoid to open.

[@RJ-vb7gh]

Heads up Dude, This fix might be a serious liability issue! The reason that the shift-brake interlock was created was because of sudden acceleration syndrome. In as much as I haven't seen a fuel injected car without one, they may be mandated by law. Occasionally computer controlled cars would surge when placed in gear and the car would leap forward. This was a notable defect in Audis and police cars back in the late 1980s and people were actually killed. Plus it made for some funny videos of cop cars lurching through McDonalds restaurants. The more correct fix would be to bypass the computer and install a relay on the brake light circuit that would send a ground to the shifter solenoid. (I was kind of distracted and might be wrong, but if you need a positive feed to the shift solenoid.. you don't even need the relay.) In any case if the car never surges or the driver is careful, your fix is fine... but if the car does surge forward without the driver's foot on the brake and the car runs over someone, you are the guy who disabled the system... on video... and you might be faced with an expensive liability issue. So... maybe a written waiver might help, but personally I might show a customer how and where to make the solder joints you did, but I don't think I'd do it for them myself. Ivan, I don't want to be a downer, and I've done my fair share of kluges on my own cars over many years, but when it comes to working on other people's cars I usually don't disable safety features. I realize that I'm a dinosaur when it comes to modern tech, and I learn a lot from your videos, but people haven't changed since my day, and just because you did them a favor, doesn't mean they won't blame you when there's someone squished under their car or they gave a new meaning to the term "drive through". And yes I know that your customer will always remember to depress the break before putting the car in gear... but if I might tell a story... when I was 17 and I got my first $1.00 car, I decided not to fix the park/neutral start safety switch, because I would surely never start my own car in drive or reverse... Note it was a 425 4bbl with 365 HP. My dad rather adamantly counseled me in the error of my ways while I was extracting my car from he remains of what was apparently his favorite shrub. And he even kindly let me get out from under my dashboard once I had properly adjusted the stupid slide switch under the steering column.. And he eventually forgave me when the shrub grew back... do you know how long it takes a common stupid ornamental shrub to grow back? I do. Again, thanks for the great vids.

Well said. Also I wish my first car cost a $1.00! HA,ha,ha!

[@jonalowe]

I've got two cars in my garage right now that don't have and never had any sort of brake pedal interlock, both with fuel injection (mid 80s Jags) That Honda has essentially three locks from the factory; brake, throttle position, and if that isn't enough, a push button on the selector. You can't knock it into gear accidently without pushing the button, and you still have the park/neutral interlock for starting the car. How many damn interlocks do you need? The brake pedal interlock is a nanny state requirement. As long as the customer acknowledges the deletion and preferably signs off on it, no harm done. I probably would have checked the TPS and see if that idle reading was normal. Looks high to me. If that proved to be faulty, I'd try to correct that. If that can't be fixed, then offer the customer Ivan's solution. Ivan's solution saves the customer money as long as the customer's ok with the mod.

[@RJ-vb7gh]

@@topgun52 I would advocate that everyone start out with a $1.00 car and a tool box. It helps to have a dad who was a mechanic. It makes for a great crash course in auto mechanics and if you are really determined and industrious and don't run out of money for parts, you might even wind up with a car to drive. I've been driving since 1976 and I've never paid more than $500.00 for a personal car. On the other hand my current $500.00 car needs over $600.00 in OEM front end parts... even if I do the work. So even cheap cars don't stay that way.

[@RJ-vb7gh]

@@jonalowe Agreed.. and yes some of those mid 1980's Jags were included in those cars with sudden acceleration syndrome. Obviously sudden acceleration was rare in pretty much all cars which were susceptible to it. I've only been in one car that did it. In as much as it was a Ford Tempo, flooring itself was more curious than dangerous. But yes as I said, I whole heartedly agree, we do live in a nanny state which assumes we are too stupid to survive without some safety system to protect us from ourselves. Last month, my brake line blew out when I tried to stop for a pedestrian that just stepped in front of my car... With the benefit of a dual master cylinder, my car stopped within an inch of crushing the moron. Wanna bet that if my Crown Vic squished the fool, his survivors would be suing me now? And imagine if someone had installed a single master cylinder system into the car, how much that would wind up costing him if anyone discovered what he did? To be honest, I'm fine with single master cylinder brakes, they work great, but oddly enough... I'm kind of happy my car had a duel system because, even if I hit the emergency brake it might not have been in time to keep that pedestrian from wedging himself under my car. Most redundant safety systems seem pretty stupid, until they don't.

[@JD-iu3vi]

If that isn't a personal vehicle looks like a liability issue was created. A good solution for safety, if it's not the TPS value causing the problem, would be to build a simple CMOS AND circuit with the brake switch input and P-N inputs. The output could be a simple transistor switch controlling the ground to the solenoid.

[@richardcranium5839]

hoping that computer didnt have a resistor internally to limit amp flow, you'll find out shortly if the sollenoid cooks lol. id have done the relay to the brake lights as someone else mentioned. also in your setup i'd clipped the sollenoid ground wire to the pcm just to isolate that from the shift ind switch just in case

[@Graham_Wideman]

Hey Ivan -- a comment on the electrical aspect of this repair (as usual from this Dept :-) ): Supposing that the Transmission Range Switch can handle the ON current of the solenoid long term (though that's not a given), a problem with using that switch to turn the solenoid on and off is that during the On-to-Off transition, the solenoid coil will produce a reverse voltage spike as the solenoid's magnetic field collapses. (aka "flyback" pulse etc. I'm pretty sure you're familiar with that already.) The PCM interlock control output that originally switched that solenoid almost certainly has a diode to short that spike. But the two inputs that the solenoid is now connected to (ATP-P and ATPP) lack that diode. They probably have some input protection, but not with the current carrying capacity normally used for absorbing an inductor flyback pulse. This might or might not cause issues in this case, but something to consider when changing the control element for an inductive load. For what it's worth, other commenters suggested wiring the Trans Range Switch to a relay to drive the solenoid. This would reduce the current through the Range Switch, which is good, but the relay coil is also an inductive load, so the same consideration applies there. Separately, the concern over defeating part of the safety logic argues in favor of both the brake pedal and the Range Switch being required for turning on the solenoid. That could be accomplished by using two small relays: One controlled by the brake pedal (with flyback-pulse-shorting diode) and another by the Trans Range Switch (again with diode). Then wire the contacts of the relays in series, so that both must be ON in order to deliver ground-side path to the solenoid. But all that said... I'm betting on the 9.8% throttle position as a likely culprit :-).

Excellent comment, very detailed explanation! Love the critical thinking. I will have to follow up with these points 👍

@@PineHollowAutoDiagnostics Hey, just a small effort on my part compared to the effort and discussion you put into these videos for us!

Did I notice steel toes lol

Great illustration,thanks. Hey guys wat must i do or wat link must I use to get wiring diagrams.

[@Cowboy_Ash]

Throttle position sensor is the problem. Cleaning the throttle body might fix it and it probably needs it anyway.

Great video Ivan.Were did buy that little solding iron i would like to buy one.

[@mixedboi]

You did the right thing Иван, that lady has to have just a tiny bit of common sense and she'll be golden. I've got an Accord EU cl7 too and guess what, my automatic climate control is monitored by the ECU as well. Most reliable car ever though.

[@howardiko7156]

Nice ivan would you only want the solenoid to operate with the brake applied?

[@jj-tt6gl]

Awsom configured.

Smashing russian work around lol :-D Was i asleep as i didn't see you test the wire resistance from the pcm pin to the solinoid?. i am asleep most of the time :-D

[@HouseCallAutoRepair]

How many conductors in the brake light switch? I've seen separate switches AND double throw switches...

[@robertb2468]

When pressing the brake my cruise control wouldn't disengage, my friend said if the brake lights work is is not a switch problem. I checked under the dash and sure enough it was a double pole switch. One side for brakes and the other for the cruise and other things. It's a 2007 focus. I Russian fixed the cracked switch body and works fine.

[@chadow86]

Could it be the tps be reading higher than "safe" limit or value and blocking out the parking lock/shift lock

[@TonyRule]

Yeah, 10% does seem a bit high. It's an AND logic gate in the PCM. Perhaps it's looking for a lower value.

[@rustlebruxz0013]

My thought too. Why is TPS 9.8% at rest instead of zero?

[@chadow86]

@@rustlebruxz0013 one would think a rest point would be 0-3%

[@garyjohnson801]

I think I would have ran a ground to the brake pedal switch so the brake would still work
