| C2769 | Longitudinal Acceleration Sensor Electrical Failure | This DTC is related to a 4WD ABS module concern. If this DTC is set on this vehicle an incorrect ABS module has been installed, the ABS module has not been configured or the ABS module has not been configured correctly. VERIFY the module part number matches the required module for the vehicle. If the part number does not match the required part number for the vehicle. INSTALL the correct ABS module. CARRY OUT the Programmable Module Installation (PMI) manually from the as-built data. REFER to MODULE CONFIGURATION SYSTEM article. TEST the system for normal operation. |
| C2770 | Longitudinal Acceleration Sensor Plausibility Failure | This DTC is related to a 4WD ABS module concern. If this DTC is set on this vehicle an incorrect ABS module has been installed, the ABS module has not been configured or the ABS module has not been configured correctly. VERIFY the module part number matches the required module for the vehicle. If the part number does not match the required part number for the vehicle. INSTALL the correct ABS module. CARRY OUT the Programmable Module Installation (PMI) manually from the as-built data. REFER to MODULE CONFIGURATION SYSTEM article. TEST the system for normal operation. |
| C2777 | Sensor Cluster Bus Failure | GO to PINPOINT TEST G . |
| C2778 | Sensor Cluster Power Supply Failure | GO to PINPOINT TEST G . |
