DTC CONFIRMATION PROCEDURE
1.PERFORM DTC CONFIRMATION PROCEDURE
With CONSULT
1. Turn ignition switch ON.
2. Using CONSULT, perform “SELF- DIAGNOSIS RESULTS” of HVAC.
3. Check if any DTC No. is displayed in the self-diagnosis results.
Is DTC detected?
YES >> Refer to HAC-69, "Diagnosis Procedure".
NO >> Inspection End.
Diagnosis ProcedureINFOID:0000000009463140
Regarding Wiring Diagram information, refer to HAC-34, "Wiring Diagram".
1.CHECK AIR MIX DOOR MOTOR LH COMMUNICATION SIGNAL
