Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY SOLENOID VALVE OPERATION • Turn the ignition switch off. • Connect the WDS or equivalent to the DLC-2. • Turn the ignition switch to the ON position (engine off). • Access solenoid valve PIDs using the WDS or equivalent. • Does the solenoid valve operate? | Yes | Go to the next step.
No | Replace the DSC HU/CM, then go to the next step. (See DSC HU/CM REMOVAL/INSTALLATION.)
2 | VERIFY DTC TROUBLESHOOTING COMPLETED • Clear the DTC from the memory. (See Clearing DTCs Procedures.) • Start the engine and drive the vehicle at 10 km/h {6.2 mph} or more. • Gradually slow down and stop vehicle. • Are the same DTCs present? | Yes | Repeat the inspection from Step 1. If the malfunction recurs, replace the DSC HU/CM. (See DSC HU/CM REMOVAL/INSTALLATION.)
No | Go to the next step.
3 | VERIFY AFTER REPAIR PROCEDURE • Are any other DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC Table.)
No | DTC troubleshooting completed.
