DTC | C1145 C1155 C1165 C1175 | RF ABS wheel-speed sensor LF ABS wheel-speed sensor RR ABS wheel-speed sensor LR ABS wheel-speed sensor
DETECTION CONDITION | • Abnormal input is detected.
POSSIBLE CAUSE | • Open or short to ground circuit in harness between ABS HU/CM terminal and ABS wheel-speed sensor(s) terminal below - ABS HU/CM terminal Q-RF ABS wheel-speed sensor terminal B - ABS HU/CM terminal O-RF ABS wheel-speed sensor terminal A - ABS HU/CM terminal I-LF ABS wheel-speed sensor terminal B - ABS HU/CM terminal K-LF ABS wheel-speed sensor terminal A - ABS HU/CM terminal E-RR ABS wheel-speed sensor terminal A - ABS HU/CM terminal C-RR ABS wheel-speed sensor terminal C - ABS HU/CM terminal U-LR ABS wheel-speed sensor terminal B - ABS HU/CM terminal W-LR ABS wheel-speed sensor terminal D • ABS wheel-speed sensor(s) malfunction

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | INSPECT ABS WHEEL-SPEED SENSOR CIRCUIT FOR SHORT TO GROUND • Turn ignition key to OFF. • Inspect continuity between suspected sensor terminal(s) of ABS HU/CM connector (harness side) and ground(s). - RF ABS wheel-speed sensor (+): Q - RF ABS wheel-speed sensor (-): O - LF ABS wheel-speed sensor (+): I - LF ABS wheel-speed sensor (-): K - RR ABS wheel-speed sensor (+): E - RR ABS wheel-speed sensor (-): C - LR ABS wheel-speed sensor (+): U - LR ABS wheel-speed sensor (-): W • Is there continuity? | Yes | Repair or replace harness for short to ground circuit between ABS HU/CM and ABS wheel-speed sensor(s), then go to Step 3.
No | Go to next step.
2 | INSPECT ABS HU/CM TO ABS WHEEL-SPEED SENSOR CIRCUIT FOR OPEN CIRCUIT • Inspect continuity between suspected sensor terminal(s) of ABS HU/CM connector (harness side) and ABS wheel-speed sensor connector. (vehicle harness side) - RF ABS wheel-speed sensor (+): Q-B - RF ABS wheel-speed sensor (-): O-A - LF ABS wheel-speed sensor (+): I-B - LF ABS wheel-speed sensor (-): K-A - RR ABS wheel-speed sensor (+): E-A - RR ABS wheel-speed sensor (-): C-C - LR ABS wheel-speed sensor (+): U-B - LR ABS wheel-speed sensor (-): W-D • Is there continuity? | Yes | Repair or replace poor connections of ABS HU/CM connector and/or ABS wheel-speed sensor connector(s), then go to next step.
No | Repair or replace harness for open circuits between ABS HU/CM and ABS wheel-speed sensor(s), then go to next step.
3 | VERIFY TROUBLESHOOTING COMPLETED • Make sure to reconnect all disconnected connectors. • Clear DTC from memory. (See Clearing DTCs Procedures.) • Is same DTC present? | Yes | Replace ABS CM, then go to next step.
No | Go to next step.
4 | VERIFY AFTER REPAIR PROCEDURE • Is there any other DTC present? | Yes | Go to applicable DTC inspection.
No | Troubleshooting completed.
