Diagnosis ProcedureINFOID:0000000003774631
1.CHECK IPDM E/R
CONSULT-III DATA MONITOR
1. Turn the lighting switch 2ND.
2. Select “HL WASHER REQ” of IPDM E/R data monitor item.
3. Operate the headlamp washer.
4. Check the status of “HL WASHER REQ”.
Is the status of item normal?
YES >> Refer to WW-32, "Component Function Check".
NO >> GO TO 2.
2.CHECK COMBINATION SWITCH
Perform the inspection of the combination switch. Refer to BCS-76, "
Symptom Table".
Is combination switch normal?
YES >> Replace BCM. Refer to BCS-78, "Exploded View".
NO >> Repair or replace the applicable parts.
