DETECTION CONDITION

•  Solenoid valve operation does not correspond to solenoid ON/OFF commands from the DSC/RSC HU/CM.

POSSIBLE CAUSE

•  Open or short circuit in the DSC/RSC HU/CM internal solenoid valves

•  Solenoid valve malfunction

•  Poor connection at connectors (female terminal)

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY DTC INSPECTION • Turn the ignition switch off. • Connect the M-MDS to the DLC-2. • Turn the ignition switch to the ON position (engine off). • Clear the DTC from the memory. (See ON-BOARD DIAGNOSIS [DSC/RSC].) • Re-perform the DTC inspection. • Is more than one solenoid valve-related DTC output?	Yes	Go to the next step.
1		No	Replace the DSC/RSC HU/CM, then go to the Step 3. (See DSC/RSC HU/CM REMOVAL/INSTALLATION [L.H.D.].) (See DSC/RSC HU/CM REMOVAL/INSTALLATION [R.H.D.].)
2	INSPECT DSC/RSC HU/CM POWER SUPPLY AND GROUND CIRCUIT FOR OPEN CIRCUIT • Measure the voltage between DSC/RSC HU/CM terminal AL and terminal A. • Is the voltage more than 10 V?	Yes	Replace the DSC/RSC HU/CM, then go to the next step. (See DSC/RSC HU/CM REMOVAL/INSTALLATION [L.H.D.].) (See DSC/RSC HU/CM REMOVAL/INSTALLATION [R.H.D.].)
2		No	Repair or replace the wiring harness, then go to the next step.
3	VERIFY DTC TROUBLESHOOTING COMPLETED • Clear the DTC from the memory. (See ON-BOARD DIAGNOSIS [DSC/RSC].) • Are the same DTCs present?	Yes	Repeat the inspection from Step 1. If the malfunction recurs, replace the DSC/RSC HU/CM, then go to the next step. (See DSC/RSC HU/CM REMOVAL/INSTALLATION [L.H.D.].) (See DSC/RSC HU/CM REMOVAL/INSTALLATION [R.H.D.].)
3		No	Go to the next step.
4	VERIFY AFTER REPAIR PROCEDURE • Are any other DTCs present?	Yes	Go to the applicable DTC inspection. (See ON-BOARD DIAGNOSIS [DSC/RSC].)
4		No	DTC troubleshooting completed.
