Description
Detects door open/close condition and transmits the signal to BCM.
1. CHECK FRONT DOOR SWITCH INPUT SIGNAL
Check ("DOOR SW-DR" and "DOOR SW-AS") in "DATA MONITOR" mode with CONSULT.
Refer to BCS
"RETAINED PWR : CONSULT Function (BCM - RETAINED PWR)" or BCS "RETAINED PWR :
CONSULT
Function (BCM - RETAINED PWR)".
Is the inspection result normal?
YES >> Front door switch circuit is OK.
NO >> Refer to PWC "Diagnosis Procedure".
Regarding Wiring Diagram information, refer to PWC "Wiring Diagram".
1. CHECK HARNESS CONTINUITY
Check voltage between BCM connector and ground.
Is the measurement value within the specification?
YES >> Replace BCM. Refer to BCS "Removal and Installation" or BCS "Removal and Installation".
NO >> GO TO 2
2. CHECK HARNESS CONTINUITY
1. Turn ignition switch OFF.
2. Disconnect BCM and front door switch.
3. Check continuity between BCM connector and front door switch connector.
4. Check continuity between BCM connector and ground.
Is the inspection result normal?
YES >> GO TO 3
NO >> Repair or replace harness.
3. CHECK BCM OUTPUT SIGNAL
1. Connect BCM connector.
2. Check voltage between BCM connector and ground.
Is the inspection result normal?
YES >> GO TO 3
NO >> Repair or replace harness.
3. CHECK BCM OUTPUT SIGNAL
1. Connect BCM connector.
2. Check voltage between BCM connector and ground.
