2021 Rebel. DASM installed from the he factory. I'd like to ammend my previous comment on the new equipment. As I have recently been informed, the ABS module and hcu were not the correct models (basically, installed for no reason) I now have a new set of these components ordered. They are coming from a 2023 Laramie which has ACC from the factory (I figure they should be the right components as they have the same part numbers listed in these posts with only difference being the last two letters) I reinstalled my original CC switch in the meantime to get my function back which worked, but still have the lights on the dash for no fcw. I've restored the BCM from the backup made at the beginning of this process, but the lights are still on.
Thanks Vincent, I got the parts in and installed them. I did the rear harness with the outer sensors and the new module. I already have the 6 sensors in the front. I got the new harness and additional sensors installed. Before I made any of the config changes, I got the ParkSense Unavailable & Needs Service. This is only showing an issue on the rear parksense. I have went back and checked all my connections and I still got the errors.
Did you install the new parktronics module?
Yes, that’s the module on the left kick panel on teh drivers side, right?
Yes, you probably need to enable it through AlfaOBD.
I will leave that decision to the professionals, but I would only do that as a last resort. The FCW Light is expected as part of the procedure. The Mopar online parts site shows you what parts are interchangeable as far as the last 2 digits. The ABS Module and HCU’s that I installed were not the ones listed on the parts list. I would guess that one of the components is either bad or not correctly labeled.
Hi vincentw56, I've read quite a few of your helpful posts as well, great to meet you and thank you...
I had to go to the dealer for mine as have others. But some others did not. I guess it is hit and miss. The post you referenced has good info on what needs to be done. He also referenced another post about it. AlfaOBD will do it. I think when the OP and I did it, it was broken and why it didn't work for us.
I didn't end up needing to do that, I wasn't able to even see the proper button that the instructions mentioned. See post 763 and the ones after for my adventure in this. For reference, I have a 22 Rebel, only came with FCW, no BSM, LKA, ACC, etc.
Thanks! I must be blind
Just noticed this is for a TRX. Will that windshield be the same as a Laramie?
Yes, there's no difference on windshields.
I have both JScan and AlphaOBD. I could not get Alpha to initialize the new part. It turns out that it was in plant-mode and had to be disabled first - prior to initialization. In JScan that was easier to fix than Alpha. I also was able to do the FULL initialization using JScan over Alpha. it walked me through all three steps - static initialize - G (whatever) lat. Calibration - and clear Rolls info. No need to fuss with hacking Alpha to get to the Lat acceleration calibration.
