Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY OTHER DTC HAS BEEN RECORDED • Has DTC C1186 and/or C1266 also been stored? | Yes | Go to the applicable DTC inspection.
No | Go to the next step.
2 | INSPECT ABS FUSE CONDITION • Is ABS fuse (60 A) normal? | Yes | Go to the next step.
No | Replace fuse, then go to Step 6.
3 | INSPECT MOTOR RELAY POWER SUPPLY CIRCUIT FOR OPEN CIRCUIT • Turn the ignition switch off. • Disconnect ABS (ABS/TCS) HU/CM connector. • Turn the ignition switch to the ON position (engine off). • Measure voltage between ABS (ABS/TCS) HU/CM terminal AB (harness-side) and ground. • Is voltage B+? | Yes | Go to the next step.
No | Repair or replace harness for open circuit between battery positive terminal and ABS (ABS/TCS) HU/CM terminal AC, then go to Step 6.
4 | INSPECT PUMP MOTOR GROUND CIRCUIT FOR OPEN CIRCUIT • Turn the ignition switch off. • Inspect continuity between ABS (ABS/TCS) HU/CM terminal AD (harness-side) and ground. • Is there continuity? | Yes | Go to the next step.
No | Repair or replace harness for open circuit between ABS (ABS/TCS) HU/CM terminal AB and ground, then go to Step 6.
5 | VERIFY PUMP MOTOR OPERATION • Turn the ignition switch off. • Connect WDS or equivalent to DLC-2. • Turn the ignition switch to the ON position (engine off). • Access ABS_POWER and PMP_MOTOR active command modes using the WDS or equivalent. • Does pump motor operate? | Yes | Go to the next step.
No | Repair ABS (ABS/TCS) HU/CM, then go to the next step.
6 | VERIFY TROUBLESHOOTING COMPLETED • Clear the DTC from the memory. (See Clearing DTCs Procedures.) • Start engine and drive vehicle at 10 km/h {6.2 mph} or above. • Gradually slow down and stop vehicle. • Is same DTC present? | Yes | Replace ABS (ABS/TCS) HU/CM, then go to the next step.
No | Go to the next step.
7 | VERIFY AFTER REPAIR PROCEDURE • Is there any other DTC present? | Yes | Go to the applicable DTC inspection. (See DTC Table.)
No | Troubleshooting completed.
