DTC | C1194 C1198 C1210 C1214 C1242 C1246 C1250 C1254 C1400 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 HU/CM.
POSSIBLE CAUSE | • Solenoid valve malfunction • Open or short circuit in the DSC HU/CM internal solenoid valves • Poor connection at connectors (female terminal)

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY SOLENOID VALVE OPERATION • Turn the ignition switch to the LOCK position. • Connect the M-MDS to the DLC-2. • Turn the ignition switch to the ON position (engine off). • Access the active command mode for the solenoid valve using the M-MDS. • 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 ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].) • 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? (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].) | Yes | Repeat the inspection from Step 1. If the malfunction recurs, replace the DSC HU/CM, then go to the next step. (See DSC HU/CM REMOVAL/INSTALLATION.)
No | Go to the next step.
3 | VERIFY AFTER REPAIR PROCEDURE • Are any other DTCs present? (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].) | Yes | Go to the applicable DTC inspection. (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].)
No | DTC troubleshooting completed.
