GrandVoyager ABS Light: Lateral Sensor Failure Alert

Had the same issue on my 2010 Town & Country diesel. The diagnostic scan revealed problems with the lateral acceleration sensor, affecting both traction control and yaw rate monitoring. The safety warning lights stayed on continuously. The problem turned out to be more than just a sensor malfunction. The ABS control unit was defective and water had damaged internal components. This is a critical safety system that handles electronic stability control and emergency brake assistance. The repair required specialized diagnostic equipment to properly calibrate the new control unit after installation. Regular shops often lack the right tools for this job. The system needs proper initialization and coding to work with the vehicle's other control modules. A certified shop with the correct diagnostic tools is essential for this repair. The entire job took about 4 hours. Given that this affects core safety systems like ABS and traction control, getting it fixed properly is crucial. This isnt a repair where taking shortcuts makes sense. The symptoms you describe match exactly what happened with my vehicle, and waiting too long risks complete ABS failure.

Thanks for sharing your experience. That description matches my situation exactly. I also took mine to a certified shop and they found water damage in the ABS control unit. They had to recalibrate the steering angle sensor after replacing the unit to get the electronic stability system working properly again. Would you mind sharing what the total repair cost was in your case? Im curious if prices have changed much since then. Also, have you had any recurring issues with the ABS or electronic control systems since the repair was done?

Following my experience with the GrandVoyager traction control issues, I can report everything has worked flawlessly since the repair. The total cost came to 1000€ for fixing the affected control unit, which included complete recalibration and testing of all related systems. The lateral sensor fault that initially triggered the diagnostic scan warnings has been completely resolved. The electronic stability system now functions perfectly, and the ABS performs as intended. No warning lights have reappeared in the instrument cluster. The certified shop did a thorough job ensuring all control modules were properly synchronized after the repair. When dealing with these critical safety systems, the extra cost for proper diagnostic equipment and expertise proved worthwhile. Its been two years since the fix, and Ive had zero recurring issues with any of the stability or brake control systems. The price you mentioned sounds in line with what I paid, considering the complexity of the repair and the specialized equipment needed for proper calibration.

I decided to take my GrandVoyager to a certified dealer after reading these responses. The diagnostic scan confirmed water damage in the ABS control unit, just like you described. The repair cost came to 950€, which included full recalibration of the electronic stability control system and yaw rate sensors. The mechanic showed me where water had corroded the unit connections. They had the right diagnostic equipment to properly initialize everything after installation. The whole job took about 5 hours, but the vehicle stability systems are all working perfectly now. No more warning lights on the dash. Worth every cent to have it done right. The traction control and ABS are functioning like new. Really glad I chose a certified shop instead of trying to save money at a regular garage. These safety systems are too important to risk an improper repair.
