Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY OTHER DTC HAS BEEN RECORDED • Has any ABS wheel speed sensor, sensor rotor, solenoid valve, pump motor, or motor relay related DTC been output? | Yes | Go to applicable DTC inspection.
No | Go to next step.
2 | INSPECT DSC HU/CM OPERATION • Perform DSC HU/CM system inspection. (See DSC SYSTEM INSPECTION.) • Is it normal? | Yes | Go to next step.
No | Replace DSC HU/CM, then go to next step.
3 | VERIFY CURRENT STATUS OF MALFUNCTION • Clear DTC from memory. (See Clearing DTCs Procedures.) • Start engine and drive vehicle at 10 km/h {6.2 mph} or above at least one minute. • Gradually slow down and stop vehicle. • Is the same DTC present? | Yes | Replace DSC HU/CM, then go to next step.
