| C110A | ABS Active Circuit Short to Battery | If any other DTCs are present (except B1342), diagnose those DTCs first. This DTC is used for aftermarket equipment (like an engine braking device) and indicates that there is a concern in the aftermarket equipment. When in use, this circuit (pin-14 of the ABS module electrical connector) informs the aftermarket equipment that an ABS event is in progress. If the vehicle is equipped with aftermarket equipment, VERIFY that those systems are functioning correctly. ISOLATE the aftermarket equipment and CARRY OUT the ABS module self-test. If the DTC does not return, the concern is in the aftermarket equipment. If the DTC returns or if the vehicle is not equipped with any aftermarket equipment, DISCONNECT the ABS module electrical connector and INSPECT the connector for corrosion, water intrusion and other contamination. If contamination is present, CLEAN or REPAIR the connector as necessary. CLEAR the DTC. REPEAT the self-test. If no contamination is present, CLEAR the DTC and REPEAT the self-test. If the DTC returns, INSTALL a new ABS module. REFER to ANTI-LOCK BRAKE SYSTEM (ABS) MODULE . Using the scan tool, CARRY OUT the IVD Initialization sequence. CLEAR the DTC. REPEAT the self-test. |
