ProMaster DISASTER Van - Part 2: Transmission LIMP MODE? (P0760)

[@BehindTheCounter_TFSO]

Hey Ivan, you bring up a valid point about being compensated for your work. First of all, you didn't manufacture it, design it, buy it, or break it. You're there to resolve their issue, and I don’t think you’re running a soup kitchen. For them to replace that truck today would cost them an arm and a leg. This wasn’t just a common problem where you could rely on a Google search. In this case, you needed a professionally trained technician. Unfortunately, in this case, it was going to take some time. I could easily see someone trying to sell this guy a transmission, let alone just a valve body. In the end, you had a confirmed fix. You're not getting that from Google.

[@adamtrombino106]

Figure it this way. You go to a dealer and say "Fix it", they do and it costs XYZ. If you were to ask for a 'discount' they'd laugh you right outta the place and the vehicle stayed put. The very fact that Ivan entertained the idea shows his integrity as well as understanding of real world problems for the customer. The room gets filled with 'what aboutisms' pertaining to all the hrs spent by 2 guys with 2 seperate shops, traveling, etc. and they are valid points. What it boils down to is a poor design with known issues that somebody has to deal with, and then offer some sort of warranty. As designed, that cannot happen. Water intrusion issues plague these vans, from computer systems, to head and tail lights constantly blowing out, to caliper pins rusting up and seizing. They are a hot mess.

Very true, but I think this case was unique. This van sat on a dealer lot for something like over a year, with ALL the water from the windshield pouring directly onto the computer. That's a pretty fringe case.

[@truracer20]

These vans have known issues with the cowl leak. It is preventable. kzbin.info/www/bejne/onqmfa2uZs1-jtksi=5D2HKRAKAOxvuKUt . This is a commercial vehicle, it is the livelihood of its owner, this van has been at the Chrysler dealership 3 times, have they checked the drains? No! Have the owners researched common problems? Unlikely. If the owners and service shops actually looked over this vehicle with an eye toward preventative maintenance then issues would be spotted before they become extremely expensive. Every morning the hood should be up on a commercial vehicle. Check your oil, check your coolant level, look for the general condition of the entire engine compartment. Look for leaks, listen for noises. Do a walk around, check your lights, check your tires, check the general overall condition of the exterior. Factory maintenance intervals should be followed at a minimum. This van doesn't get any of that, they just ignore the bulb failure warning on the instrument panel. I'm going to bet the owners flatly decline recommended services when they take it to a shop for specific repairs or service. It's important to have a shop that is trustworthy doing your maintenance so when your vehicle needs something you can trust that it does and the shop isn't just trying to bilk you. This problem is user error to a large extent, with service shops lack of action being the other factor.

[@pcar5]

The problem was caused by a clogged drain. This is a not uncommon problem and can cause much worse problems than what happened here. Clearing the drains is a maintenance item which very few owners ask to have done. It is not a design problem.

[@promastersonly1419]

That was indeed leaves and sticks and such in the main and only cowl drain tube, which is a close to 2" affair and generally doesn't cause an issue. Even if it falls off, water generally goes harmlessly onto the tail of the transmission. But like in this case, if that drain is plugged, 100% of the water coming from the windshield will be forced to go somewhere. In this case, the water had MADE paths that it normally wouldn't have, taking out the seal for the DS windshield wiper and some other rubber seals. Clearly, an extreme case. I believe this van sat on a lot for over a year as well.

I can tell you have never worked at a Dealer Ship. Most Dealers have 2-3 guys out of twenty that are pretty good. The rest are in training. Dispatch has to move work around the shop. Flat rate is a tough system. Also, people will buy a new Truck/van/car and never come back. So ten years go by and when Its all beat to $hit then a Customer shows up with some bizarre problems. And the Tech is seeing for the first time. All Dealers are run by the Lawyers. This why NO used ECMS Where did Ivan get his training ???? Not out in the back yard.

[@peterperpetua2974]

I just had one of those vans in my shop this week, had misfires and transmission codes. was still under powertrain warranty but dealer could not take if in for a few weeks. the misfire codes were just plugs and a coil, so I replaced them (under intake). The trans codes were for a signal loss of transmission speed sensor. (going in to dealer for that). Tips in Mitchel were for wiring harness issues due to water leaking down on to connector. I noticed the plastic tube (The one shown at the end of the video) was disconnected at the top.

[@promastersonly1419]

The tube fallling off at the top is common (hose clamp fix) but when that happens the water drains down behind the transmission and wouldn't cause this problem. However! - the two transmission speed sensors DO live right under that drain. We've never seen one actually go bad, but we have seen wiring damage from road debris take out the wiring. Hot tip: you CAN swap those two sensor connectors with each other. It will code immediately for a speed mismatch, and put itself into limp, but it would allow you to look at the data from each sensor, which might tell you if a sensor was bad or the wiring was bad. I think those speed sensors are under $25 each.

In europe these vans are equipped with diesel. Those are notoriously bad on glow plugs and injectors due to water sitting on the top of the engine

[@tschuuuls486]

Just wanted to comment on this. The glow plugs seize in engine so bad, you often times have to remove the cylinder head and punch them out from the inside.

I think this is a GPEC2 PCM and on the promaster there is no way a dealer can program a used one. It needs a complete clone or sometimes you can swap the eeprom and then fix the flash. The only tool I found that can do it through OBD is ECU hero.

[@alexanderzubar9593]

Really tough Diag! For all involved. One way to dry out hidden moisture is by putting the part inside a sealed vacuum chamber and applying vacuum with AC evac pump until you see no more moisture being evacuated. Vacuum chamber can be made from a gasketed sealed electrical enclosure (Example Hoffman brand) of appropriate size with the needed fittings for vacuum. Tougher problem to tackle is the hidden green crusties. Moisture removal may not solve the problem but the cost is worth the try.

[@GreyRockOne]

Thanks for posting the data streams and the tip on free Pico software, I'm a beginner here and so new to this. Thanks!

[@1McMurdoSilver]

Thanks for the challenging video. I would have tried to bake the PCM for a few hours at 125-150F or so. Also might have tried to create a weep hole in the bottom of the PCM before baking. And maybe inserting isopropyl alcohol or something that absorbs the moisture into the back of the pcm where the moisture lives. There should be a way to remove that PCM board, even though you may have to drill out the connecting points and figure out a way to reattach the board. I guess I'm a hack for $1300+

[@pingpong9656]

[@major__kong]

Drying it out may not fix it. Once water gets in, it starts acting like an electrolyte as it picks up contaminants. As it dries, it leaves traces that will bridge components and connections. And water may enter and damage components or just short them out. You really need to pull the board out and clean it, but that won't fix damaged components. The problem here is that the board is potted in, so there's a bunch of trapped moisture.

For clarity, that clip at the end is clearing some kind of blockage out of the main windshield cowl drain. With that drain plugged, the water is FORCED to go directly into the engine compartment. If I had to guess, my guess is that this blockage was the root cause of this ENTIRE problem. The Promaster has common water intrusion issues, but rarely to they dump water directly onto the PCM.

Famous last words. "The dealership was useless". I've heard that same story from a few Chrystler dealers. They just won't reflash a PCM that you supply. Company policy perhaps? And sometimes they even give you some lame sounding excuse as to why. Oh, but they will gladly sell you a new or refurbished unit. Furious sarcastic rebuttal excluded. Anyway, this reminded me of a 2003 Ford F150 I did recently. Customer complaint, water intrusion behind the driver side of the dashboard and behind center rearview mirror. Truck stalls in the rain. The sunroof drain goes into a cavity under the windshield cowl. Then that cavity has another drain that exits behind the left front tire. The cavity drain was blocked solid causing a backup to the sunroof drain. And the windshield was glued in with clear bathroom caulk. Needless to say, the caulk didn't hold.

I got some paraffin, found a plastic tray slightly larger than the connection box, melted the paraffin and encased the box with it. No more problems with water intrusion.

If they fixed a coolant leak and there’s also coolant in the connector, that section of the harness needs to be replaced. It got pushed from the sensor to the ECM. I wonder if there’s a tool to air pressurize a wiring harness at the connector and force the fluid back thru away from the ECM.

Actually Ivan, the dealer is correct. These used ECM's can only be done if they are cloned or hotswapped with witech. The hotswap does not always work. They are not like older Chryslers. When you program a new dealer ECM there is no key programming. The BCM transfers the key data during the programming event. When you program keys they only program to the BCM. The dealer was right in this case unless you wanted to pay them too fart around with the used one it just simpler to do new one unless you can just clone it.

What I find interesting is the inductive kick is only associated with the final cutoff, not the PWM pulses "during". That indicates something more than a simple switch to ground going on. Not related to the problem, just an interesting (odd?) design.

I have been chasing the same problems the van will misfire and flash more lights on in the dash Cruise control won’t turn on and the air conditioner turns on by its self. The tac bounces all over the place. I sprayed wd-40 all over the computer and ever connection leading to it. After about ten min I shut it off and pulled the neg off the battery and then it started fine. It’s definitely moister I feel.

Why doesn't the factory fill those wiring plugs with dielectric grease at the factory? wouldn't that help prevent water intrusion?

[@promastersonly1419]

Normally, the bulk plugs on the PCM never cause a problem. This van was special because with the cowl drain tube blocked, 100% of the water from the windshield was forced to find a new path, and MADE it's own path which happened to include the computer.

[@bones007able]

@@promastersonly1419 I hear you , but Dodge has the same problem with their TPIM's the underside connectors get green and kills the vehicle ...been there done that

[@promastersonly1419]

I'm in a unique position, because only working on one vehicle we learn all the common failures and weak points, and kind of ignore the rest. No TIPM on this van. Also no EGR, no fuel filter, no fuel return system, no TCM, no MAF, no caster or camber, and a lot of other stuff it doesn't have or has simplified versions. @@bones007able

[@arthuraucar3696]

What is triggering that pressure switch state.? Is it actually coming from the pcm, or is it from the transmission.? Fluid by-pass in the valve body can also cause this problem!!!

[@AB-fs4gm]

Can you spray the connectors with something like flex seal?

[@settjessettje9323]

Try aluminum foil over the connectors and over Computer. Cheap and waterproof. I would cover ALL of the connectors because you know others are getting wet too.

[@MWestern-m4g]

Every time I drive it in the rain it fails. Don't drive it in the rain. Doc: My arm hurts when I lift it. Don't lift it

[@waynedieleman2857]

I saw in another video that there’s 3 drains in the cowl for the promaster, always getting plugged with leaves and crud

[@jamesmorehouse9575]

My dodge caravan sport was doing about the same ,I had to change two sensors on the top of transmission after change the two sensors it run like it use too.

[@theblackhand6485]

What was that extra footage on the end of the video?

[@nickb7609]

think its the cowl drain hose that was blocked causing the water to flow onto the connectots/ecm being cleaned out

[@WMautoservice]

Hi brother, nice video! What scanner you recommend someone buy to run a shop for various car brands?

[@phill3144]

I have seen oil travel through wiring from oil pressure sensors, is he sure the same isnt happening from a water temp sensor and coming out into the ecm plug via the wiring itself

[@tube8533]

You did it!

[@alanjacko007]

I never understood how this water gets in, aren’t these connectors rated at something like IP67?

[@ludvigericson6930]

Why didn’t you open the PCM and dry it as best as you could? Is it hard to get it back together?

[@dublindave5795]

Ivan, Would filling the connector with silicone grease (dielectric) keep it watertight?

[@danamcintyre3565]

The line he showed was that a drain hose from the cow or what was it ?

[@Citizen63-j8k]

Install rain gutter over ECM! 😁

[@rogerstlaurent8704]

I would call Gutter Guard and have them fix the water issue LOL

[@tonychalmers9867]

Not unusual to see coolant in the gearbox harness on Audi Q7 and related cars. They put a coolant solenoid on the same harness and when it leaks capillary action takes it straight to the connector knocking out the gearbox.

[@plowkingf15]

Probably jam those connectors with di electric grease I have to do that to my headlight harness connectors or high and low beam will short between terminals from grime and road salt.

[@MrFishface5]

why couldnt you program a used computer?

[@michaelschmidt7014]

I would also consider filling all of the connectors with dielectric grease to prevent water intrusion, thoughts?

[@greggc8088]

Fact-Toyota,. GM, Ford, Chrysler, Honda, Kia/Hyundai, or any other manufacturer I can think of gives any information on whether or not a used computer can or will work in their vehicles nor how to trick them into working if need be (and there often is a bit of a trick). So, a lot of dealers won't mess with it as it may end up leaving them in a bind. Well, GM does on their Global stuff as they say not to, but not many go that far. I have so many techs ask me if a used module will work and if it's not in writing in the service info I say so.

[@GRowe1978]

I wonder if you could do at least a temporary fix on a module with water intrusion and intermittent problems by putting it in a vacuum chamber to remove the water, then spraying it down with deoxit?? I don't think I would send a customer down the road and tell them it's 100% fixed because you don't have an idea about internal corrosion. But I think it would be an interesting experiment. Especially if it was my own vehicle.

[@neilmurphy845]

Why is it called od solenoid when it seems to engage every time it changes gear

[@johnwhan7288]

I would try using a food sealer on that EC before installing it.
