DTC | C1194 C1198 C1210 C1214 C1242 C1246 C1250 C1254 C1404 C1410 C1957 C1958 | LF outlet solenoid valve system LF inlet solenoid valve system RF outlet solenoid valve system RF inlet solenoid valve system LR outlet solenoid valve system RR outlet solenoid valve system LR inlet solenoid valve system RR inlet solenoid valve system RH traction control solenoid valve system LH traction control solenoid valve system RH stability control solenoid valve system LH stability control solenoid valve system
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.
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.].)
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.].)
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].)
No | DTC troubleshooting completed.
