Hello everyone!
I would like to warn you first that my English is very bad and for that I will use Google Translate.
I own a 2015 Grand Cherokee SRT - 6.4L.
I have read dozens of forums and posts and I don't know what to do anymore. Here is my case in detail.
In February 2023, I purchased from mymoparparts.com left and right shock absorbers, original with serial numbers 68384342AC and 68384336AC ! I bought them because when going into bumps and potholes in the road, the car would rock hard and send me straight into the oncoming intercity roads. I didn't have this message before I replaced them, and I didn't have this message for nearly 2 months after replacing them with the new ones.
I drove for almost 2 months without any problems. The car behaved great already.
One day, at the self-service car wash, I noticed that a lot of mud and sand had collected in the cavity of my rear bumper from the winter period in Europe, and I decided to clean it with the water jet. Shortly after that I got the "message" and the car started to ride extremely hard. I started searching the forums for a solution.
I have checked all the cables of the shock absorbers, they are all like new, intact, without any violations. I sprayed the bushings with contact spray to try to remove any water or moisture.
After some time I read that the module with serial number 5035099ac may also be defective. I changed it too - there was no result. The error appears as soon as it is cleared from memory.
I figured the new shock absorber might have failed. I put the old shocks back in, but that was not enough either. I put my new shocks back on.
In other forums, they wrote about the control module 5035318AA , which is located under the driver's seat. Of course I changed it too and it wasn't the problem. The error appears immediately after clearing the error memory.
I don't know what to do anymore. I am reading various opinions such as cold weather with sub-zero temperatures (warm here. Close to 30 degrees celsius), overall wiring, acceleration sensors, timing sensors, height sensors and what not. In the end, I just spend a hell of a lot of money, and the result is zero.
The errors it records are:
C15BB-13 and C15BA-13.
I am asking for help from some who have faced these 2 errors and guide me to the problem because I have no hope anymore.
Thanks in advance
