COMEBACK? Honda Stuck in PARK!

Uh oh....Comeback!
2 months after implementing the "Russian Hack" fix to override the shift lock solenoid on this 2003 Honda Accord, a new transmission problem has surfaced.
It's not stuck in Park anymore, but when shifting into Drive, the car violently surges and stalls!
The "D" indicator is blinking, setting a "05-02 (P0507)- Shift Range Sensor Short Circuit" code.
Is this related to the wiring modifications we did in Part 1??

I agree. It would be silly to replace the ECM just to make sure that interlock part of the system works like intended. Your hack works just as well. You saved your customer a bunch of money. Good job.

Great original fix and great follow up repair. Who would have guessed the circuit would start working again.

[@TheOmegaman69]

I would like to make a few comments, if I could. These are strictly my opinion and not any criticism whatsoever. Just observations provided based only on the information I have available. First, just a couple of comments on PCM/ECM outputs and connections; 1) Connecting two (2) outputs together is not a good idea in general, if they are driven by different inputs, or if one is not sure both are open-collector outputs. This is what was found in this diagnostics (second video). Once the PCM output to the Shift Lock Solenoid (PCM, PIN E2) started working (comment on that a little later), which has the Brake Pedal Position Switch (PCM, Pin E22) and the TP Sensor (PCM, Pin A29) inputs that the Transmission Range Switch does not. This is what caused the new issue. Note, these in this case are open-collector outputs. 2) Whenever making a jumper to a different output, such as this example, the number of and size of the loads should be considered. In this example, the load of the Shift Lock Solenoid was added to the Transmission Range Switch. The SLS probably has a load that is 2, 3, or more times as large as the two (2) loads already on the Transmission Range Switch (MICU, Pin P16 and PCM, Pin D6, both inputs). One of these (probably PCM, Pin D6) has a pull-up resistor to +12V in the range of, probably, 1K - 40K. These inputs, resistor/resistors, and now the Shift Lock Solenoid are the loads on the Transmission Range Switch. Note: In this case I do not think the load is an issue as the total load is likely less than 1 Amp, and probably much less than that since the PCM (Pin E2) was driving the largest load, the Shift Lock Solenoid. However, the load on an output of any Computer Module (or other driver) should be checked if it is changed. Since this is driven by a simple switch, I assume the contacts in this switch (Transmission Range Switch) would not have an issue driving this added load. As to a possible reason the PCM output to the Shift Lock Solenoid (PCM, Pin E2) started working, I am more convinced than before (please see my comments on first video, if interested), that the TP Sensor is likely the root cause of the original issue. First thing is, you cannot trust the scanner. It shows that the TP Sensor (likely the Relative TP, a learned value) shows 4.54 degrees (or something like that) and 9.80% depressed. In the first video I commented that this should be 0%, was a learned value, and a ECM (PCM) reset and idle relearn might get it down to 0% (or close to it). Since this is a learned value, driving the car for 2 months would almost certainly give the PCM time to relearn this value and thus the Shift Lock Solenoid to start working again. This would be pretty close to the same as resetting the ECM (PCM) and doing a idle relearn. This could explain why it started working again. Just a possibility. As to why the same TP Sensor reading now, as in the first video, is 9.80%, I cannot say except that the TP Sensor value could be in the threshold area, or what is called the undefined area. As a very short explanation of what I mean, the PCM has to have some threshold, say as an example 5 degrees or 10% where it determines if the Accelerator Pedal is (TP Sensor relative value in this case) pressed or not pressed. If the value is less than 5 degrees or 10% (in this example), the PCM considers the pedal not pressed, If above this value the PCM considers the pedal is pressed. What happens though if the TP Sensor value is at, or very close to 5 degrees or 10%? The PCM does not know if the Accelerator Pedal is depressed or not depressed. There is always a +/- involved here to. The Threshold might be 5 degrees or 10% +/- 5%, as an example. That would mean IF the TP Sensor is between 4.75 to 5.25 degrees or 9.5% to 10.5% the PCM will not know if the Accelerator Pedal (TP Sensor) is depressed or not depressed, and it's Shift Lock Solenoid output may be driven low or not driven (if not driven it would be high due to internal pull-up, this is called an open-collector output). This is the Undefined area. The scanner just may not have the granularity to be able to read the value as accurately, with the resolution, of the PCM. I hope this is making sense to someone. Again, this is a very short explanation (attempted explanation) of what might be going on here. Some suggestions to possibly consider; it is my opinion that if this car ever comes back, one might consider doing one (1) or more of the following; 1) A relatively fast way to check this would be to either reconnect the original connection (PCM, Pin E2 to Shift Lock Solenoid), disconnecting the jumper wire, OR connect a test light, meter, or scope to the unconnected wire (PCM, Pin E2). Then, since the TP Sensor in the second video we saw went to 0% (or maybe 1.5%, or thereabouts) when unplugged, this PCM output could be tested 10-15 times with the TP Sensor disconnected and with it connected (i.e. with TP Sensor close to 0% and with it close to 10%). Here, we would be looking for the PCM output working reliably with the TP Sensor disconnected and working either intermittently or not at all with the TP Sensor connected. This idea here is to get the TP Sensor to 0% (or close to it), and see if it affects the PCM Shift Lock Solenoid output as compared to when it is 9.80% (according to the scanner). Results here may not be definitive, and first method here would be best as the PCM output would have it's normal load on it. Also, there maybe some other way to test this as unplugging the TP Sensor would likely generate a code and could mess with the results, making them unhelpful. 2) This is a more time consuming way to test this, but would likely also provide a somewhat more definitive result. First, remove jumper and reconnect everything to factory connection. Second, put a scope probe on three (3) signals, PCM, Pins E2, A29, and E22. These are the Shift Lock Solenoid PCM output, the TP Sensor & Brake Pedal Position Switch inputs. Then the Shift Lock Solenoid can be tested with and without the TP Sensor connected as in number 1 above, or before and after a PCM reset and idle relearn is done. 3 The last suggestion would be to remove jumper and reconnect to factory connections. Then test it 10-15 times or so. Then do a ECM (PCM) reset and a idle relearn procedure, then retest and compare results. Finally, it is my opinion (based on information available), that there is nothing wrong with the PCM/ECM. It looks very likely to me that the root cause of the original problem could be the TP Sensor input to the PCM (Pin A29). Resetting the PCM/ECM and doing a idle relearn might fix the issue, with the wiring back to factoring connections. Also, cleaning the throttle body and then doing the reset and idle relearn (if resetting and idle relearn alone doesn't work), might work. Getting the TP Sensor down closer to 0 degrees (0%), in my opinion, could very well fix the original issue, and what these suggestions would be attempting to do. Of course I could be completely wrong. Please note that I understand that time is money and not doing more work than is necessary is one of the goals of running a business. These suggestions and comments are solely my opinion and, I should say, based partly on curiosity. Both videos are very good and informational. We know there is a lot of work to make these videos and they are greatly appreciated. I did, in addition to watching this video, go back and re-watch the first video before making these comments. Thank you for making all the videos you make.

Looks like a classic cracked solder joint. Circuit board manufacturers try to put as little solder on a joint as possible which saves them money but causes a weaker connection.

[@ferrumignis]

I agree it's very likely a cracked solder joint, but long term stress, thermal cycling and vibration can cause solder to crack irrespective of quantity. I've repaired a bunch of Smart ForTwo BCMs with solder cracks on a connector that is exposed to stress from the cable harness, they have plenty of solder from the factory, and other similar connectors on the board don't crack.

[@JD-iu3vi]

@@ferrumignis I agree. I have seen solder tinned wires break from stress too. Even the thin solder joints hold unless there is vibration which is why it would seem to be a good idea to make those for automobiles more robust. But they have to save money somewhere to make the profits for the shareholder.

[@yamaha37776]

I’ve been burnt on this! I’m not sure on TP% but I know for a fact on a snap on it shows voltage, and if the TP voltage is above 0.75 volts Honda will not shift out of park. Voltage on the TPS should be 0.50, it has an IAC to control idle so throttle plate should show it’s closed. As the TPS worsens the car will have systems of harsh shifting. Great video!!! Just wanted to share my 2 cents, I don’t think you have a computer problem, I’d think it’s a tps input problem but I don’t know what 0.50 volts transfers to percentage.

[@midwestfarm757]

As I pick up more and auction cars, I have noticed a lot of PCM issues have been caused by a mechanical issue like a sensor that causes PCM to not read.

I initially thought that too, but the problem is the PNP input is looking for a ground and the interlock output is supplying a ground. There would be no way to use a diode to stop one from effecting the other in this case. If both were outputs or both inputs a diode would work. Unless you have a way I can't think of?

Ivan, did you check to see it you could perform a throttle relearn based on the TSB #SN040705. We both know the PCM showing a 9% throttle doesn’t seem right. Im sure it’s not a driver issue with the SLS, the TSB for the shifter stuck in park mentions the TPS must show 0% @ idle. What changed? Nobody knows, 9% must be that grey area where it sometimes works. That would be my guess…

[@steveboone5450]

This is 100% correct. The original problem was that the throttle body had to be relearned (there are many root causes for why it would get out of whack -- carbon buildup, cleaning, replacement, TPS replacement, etc.). There is a manual process for causing the relearn and the customer almost certainly inadvertently did this relearn which caused the driver to "mysteriously" start working properly (after now knowing that the accel is not being pressed). Suggest to revert circuit to prior form which will re-enable the critical safety interlock and all will be good.

[@PaulHigginbothamSr]

So Ivanivanovitch never removed the splice he had put in because he did not know of if the driver would stop working again. His final solution was to make the solonoid open the shifter with the key on. I can see why this is not done because my brother's granddaughter shifted his pickup to neutral rolling over a steep hill destroying the pickup and almost taking her life.
