DTC U2108: Adaptive Cruise Control: Action

The ABS module monitors vehicle deceleration during adaptive cruise control braking events to prevent an over-braking situation. This DTC sets when vehicle deceleration is greater than a specified target. This is most likely caused by an abrupt stop of the vehicle due to a collision, an extreme driving situation, a mechanical or electrical failure of the adaptive cruise control system or an internal failure of the ABS module. DIAGNOSE all other ABS module DTCs before diagnosing DTC U2108:68. If there are no other ABS module DTCs present, RETRIEVE and REPAIR all CCM DTCs. REFER to the CRUISE CONTROL SYSTEM - VEHICLES WITH: ADAPTIVE CRUISE CONTROL or DTC CHART: CRUISE CONTROL MODULE (CCM) or Collision Warning and Collision Avoidance System. If there are no CCM DTCs, INSPECT the vehicle braking system for a dragging condition or another condition that may cause rapid vehicle deceleration.
