| C0078:00 | Tire Diameter: No Sub Type Information | During straight-line driving with vehicle speed above 20 km/h (12 mph) if the speed of only 1 wheel is greater than the other 3 wheels by a predetermined amount, the ABS module sets this DTC. To determine straight-line driving, the ABS module uses information from the yaw rate sensor (sent from the RCM), the lateral acceleration sensor (sent from the RCM), the steering angle sensor (sent from the PSCM), and the wheel speed sensors. The presence of this DTC disables the selectable drive mode track mode, the line lock feature is disabled and the ESC system cannot be fully disabled. During the next ignition cycle, the DTC is reset and if the condition still exists, the ABS module sets the DTC again once the conditions have been met. Using a diagnostic scan tool, RETRIEVE and RECORD all ABS module Diagnostic Trouble Codes (DTCs). DIAGNOSE all other ABS module Diagnostic Trouble Codes (DTCs) before diagnosing C0078:00. If there are no other Diagnostic Trouble Codes (DTCs) in the ABS module, INSPECT the vehicle for a mini-spare tire in use. If a mini-spare tire is in use, REPAIR and MOUNT the original road wheel or INSTALL a new road wheel. If a mini-spare tire is not in use, VERIFY all 4 wheel and tires are of the manufacturer's recommended sizes and recommended inflation pressure. REFER to the VC label for tire size and inflation pressure information. |

| U0452:41 | Invalid Data Received From Restraints Control Module: General Checksum Failure | The ABS module uses other module messages and sensor input to calculate the yaw rate, lateral acceleration and longitudinal acceleration to verify the RCM messages. If the yaw rate, lateral acceleration and longitudinal acceleration data received from the RCM do not match the calculated values more than 2 times, this DTC is set. If ABS module Diagnostic Trouble Codes (DTCs) C0061:xx, C0062:xx, C0063:xx or C0064:xx are present, DIAGNOSE them before diagnosing U0452:41. Using a diagnostic scan tool, RETRIEVE and DIAGNOSE all RCM Diagnostic Trouble Codes (DTCs). Refer to: Airbag Supplemental Restraint System (SRS) . If there are no Diagnostic Trouble Codes (DTCs) in the RCM, the condition may be caused by an intermittent concern. SET the ignition to OFF.

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. RETRIEVE and REPAIR all other ABS module Diagnostic Trouble Codes (DTCs) before diagnosing DTC U2108:68. If there are no other ABS module Diagnostic Trouble Codes (DTCs) present, RETRIEVE and REPAIR all Diagnostic Trouble Codes (DTCs) in the CCM. Refer to: Cruise Control . If there are no Diagnostic Trouble Codes (DTCs) in the CCM, INSPECT the vehicle braking system for a dragging condition or another condition that may cause rapid vehicle deceleration. |
| U2200:00 | Control Module Configuration Memory Corrupt: No Sub Type Information | CHECK the service history for recent service actions related to the ABS module.
