NOTE:
If DTC “C1A06” is detected along with DTC “U
1000”, first diagnose the DTC “U1000”. Refer to DAS-182,
"ADAS CONTROL UNIT : DTC Logic".
DTC CONFIRMATION PROCEDURE
1.PERFORM DTC CONFIRMATION PROCEDURE
1. Start the engine.
2. Wait for approximately 10 minutes after turning the DCA system ON.
3. Perform “All DTC Reading” with CONSULT-III.
4. Check if the “C1A06” is detected as the current malfunction in “Self Diagnostic Result” of “ICC/ADAS”.
Is
“C1A06” detected as the current malfunction?
YES >> Refer to DAS-138, "Diagnosis Procedure".
NO >> Refer to GI-40, "
Intermittent Incident".
Diagnosis ProcedureINFOID:0000000006228072
1.CHECK SELF-DIAGNOSIS RESULTS
Check if “U1000” is detected ot her than “C1A06” in “Self Diagnostic Result” of “ICC/ADAS”.
Is
“U1000” detected?
YES >> Perform the CAN communication system inspecti on. Repair or replace the malfunctioning parts.
Refer to DAS-182, "
ADAS CONTROL UNIT : DTC Logic".
NO >> GO TO 2.
2.CHECK ICC STEERING SWITCH
1. Turn the ignition switch OFF.
2. Disconnect the ICC steering switch connector.
3. Check the ICC steering switch. Refer to DAS-139, "
Component Inspection".
Is the inspection result normal?
YES >> GO TO 3.
NO >> Replace the steering wheel.
3.CHECK HARNESS BETWEEN SPIRAL CABLE AND ECM
1. Disconnect the ECM connector.
2. Check for continuity between the spiral cable harness connector and ECM harness connector.
3. Check for continuity between spiral cable harness connector and ground.
