New Parts Not Available, Used Not Programmable
Hello DN members,
I'm looking for some input on what you might do if this vehicle was in your shop.
This customer (bodyshop) called me and asked if I would like to look at the no start problem with this van. It's a 2018 Chrysler Pacifica with light accident damage in the left front. From what I understand, the bodyshop bought this vehicle to repair and sell to a customer that was looking for a vehicle like this (hybrid, this particular color, etcetera). After the bodyshop got done with the repairs the vehicle still didn't start, so they had it towed to a local garage.
The local garage looked at it briefly and said they weren't comfortable going any further. From what I understood the 250 amp fuse was blown in the service disconnect, and when they put a new service disconnect in, it blew that fuse as well. From there it went to a dealer.
The dealer checked it and said it needs a power inverter module (PIM) and HV battery. This is the point where the bodyshop called me and asked if I would look at it.
I checked and found a short circuit inside the power inverter. At this point I'm not sure what caused this, or if the drive motors are okay. There is also something damaged inside the HV battery as there is power at the HV cables coming from the battery even with the service disconnect removed, the 12 volt battery disconnected, and some of the interlocks removed.
The bodyshop bought another van with a hit high in the back. I swapped the HV battery, and the engine/transmission/inverter assembly.
Now I'm left with just one problem, the vehicle still doesn't start :) Apparently the HCP (hybrid control processor) can't be programmed a second time and a new one isn't available. There are 30 on backorder, with no info on a release date.
So, is there any possibility of someone programming this at “board/chip level” with one of the devices I see being talked about on DN? I think part of the problem would be getting to the circuit boards as the covers on the PIM are “glued" in place.
Any ideas on getting this thing back on the road?
What about swapping modules from the donor vehicle . probably the steering column/rack assembly as well.
I'm not sure if I know what you mean. Are you talking about swapping all the modules that contain the VIN and then changing the VIN of the vehicle?
I wouldn't worry about changing the vin of the vehicle. Just disclose that it doesn't match the modules. Only way it will be noticed is future programming .
I can't offer much, but this sounds like a sinking ship. Bail and move on to something else before losing more time on it.
So far I didn't lose any time on it. We went into this thing with no guarantees.
I am afraid of a vehicle that an insurance company has declared a total-loss. They have more information than us and do everything to save a dollar.
It often doesn't work out as great as it sounds. In this case we are getting paid to do what the bodyshop wants.
I am afraid that I have to agree with the other people posting. Many manufacturers and Chrysler in particular won't allow module or computer swapping like we did in the old days. You didn't mention if the “new” HV battery still shows a voltage when disconnected. Also, do you still have a short circuit in the inverter? Have you tested the systems for HV leakage? Are all of the problems that you…
The replacement HV battery is working fine. No short circuit in the inverter anymore, it's been replaced. The only problem left, albeit a big one, is programming the HCP. A new one should get this vehicle up and running, but none are available for purchase. No wounds here, no loss on my end. Just trying to help someone out.
At this point the vehicle is a lost cause. Trying to build a vehicle out of several is a thing of the past. Swapping used modules on chrysler vehicles can’t be done. I would also venture to guess that at this point the vehicle likely has several modules with incorrect vin numbers as on a Chrysler swapping modules can result in the vins writing themselves to whatever is in the pcm/tipm. Not only…
Tanner, could you explain a little more about OEM's pulling the VIN files for salvaged vehicles please. First I'm hearing of this. Thanks.
GM refuses any service of salvage title vehicles. I have heard of others doing the same when it comes to giving out pin codes for these vehicles. See this thread as an example: diag.net/msg/m4k2yumeoy…
I know that there's a number of modules that can't be reused in GM. I wasn't really aware that Chrysler was doing the same thing, but it's no surprise and I imagine there are other manufacturers doing it as well. As far as I can tell none of the other modules changed over to the donor vehicle VIN.
