DTC U2108: Adaptive Cruise Control

Failure	Action
00	In order to detect errors in the CCM, the cruise control system is momentarily shut off during a driver braking event. This DTC sets when the ABS module detects cruise control system activation during a driver braking event. This is most likely caused by a network communication concern or an internal failure of the CCM. RETRIEVE and REPAIR all DTCs in the CCM. REFER to the CCM DTC CHART .
68	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 CCM DTC CHART . If there are no CCM DTCs, INSPECT the vehicle braking system for a dragging condition or another condition that may cause rapid vehicle deceleration.
