The problem: in affected vehicles, a dealership technician may have programmed the vehicle’s brake system control modules (BSCM) with the incorrect calibrations.
The hazards: if the vehicle has the wrong BSCM calibrations, this could affect the performance of various vehicle safety systems, including electronic stability control, traction control and anti-lock braking. Additionally, this condition can cause these systems to perform poorly in certain low traction conditions and may lead to the total loss of trailer braking while towing. For this reason, vehicles with this condition have an increased risk of a crash.
The fix: dealerships will be instructed to reprogram the BSCM module with the correct calibrations and data files. This will prevent the conditions listed above and ensure all of the vehicle’s safety systems perform as intended.
Affected components: BSCM module.
Number of affected vehicles: a total of two (2) vehicles are affected by this problem. Both vehicles are located in the United States.
