Diagnostic Procedure

DTC C0001:01, C0002:01, C0003:01, C0004:01, C0010:01, C0011:01, C0014:01, C0015:01, C0018:01, C0019:01, C001C:01 OR C001D:01 (DSC HU/CM) DIAGNOSTIC PROCEDURE

Step	Inspection	Results	Action
1	VERIFY SOLENOID VALVE OPERATION Verify if the solenoid valve operates using the simulation item corresponding to the displayed DTC. (See SIMULATION INSPECTION .) (See SIMULATION TABLE [DSC HU/CM] .) C0001:01 TCS_ISOLAT_VLV_1 C0002:01 TCS_ISOLAT_VLV_2 C0003:01 TCS_SUPPLY_1 C0004:01 TCS_SUPPLY_2 C0010:01 TCS_ISOLAT_VLV_L/F C0011:01 TCS_DUMP_L/F C0014:01 TCS_ISOLAT_VLV_R/F C0015:01 TCS_DUMP_R/F C0018:01 TCS_ISOLAT_VLV_L/R C0019:01 TCS_DUMP_L/R C001C:01 TCS_ISOLAT_VLV_R/R C001D:01 TCS_DUMP_R/R Does the solenoid valve operate?	Yes	Go to the next step.
1		No	Replace the DSC HU/CM and perform the repair completion verification procedure. (See DSC HU/CM REMOVAL/INSTALLATION [L.H.D. (US)] .)
Repair completion verification 1	VERIFY THAT VEHICLE IS REPAIRED Install/connect the part removed/disconnected during the troubleshooting procedure. Clear the DTC recorded in the memory. (See CLEARING DTC .) Perform the DTC inspection for the DSC HU/CM. (See DTC INSPECTION .) Is the same Pending DTC present?	Yes	Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error. (See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW (US) .) If the CAN communication is normal, perform the diagnosis from Step 1. If the malfunction recurs, replace the DSC HU/CM, then go to the next step. (See DSC HU/CM REMOVAL/INSTALLATION [L.H.D. (US)] .)
Repair completion verification 1		No	Go to the next step.
Repair completion verification	VERIFY IF OTHER DTCs DISPLAYED Perform the DTC inspection. (See DTC INSPECTION .) Are any DTCs displayed?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting.
Repair completion verification		No	DTC troubleshooting completed.
