Diagnosis Procedure

INFOID:0000000009579015

Regarding Wiring Diagram information, refer to 

PCS-72, "Wiring Diagram"

.

1.

CHECK BLOWER RELAY CONTROL SIGNAL VOLTAGE

1. Remove blower relay.

2. Check voltage between blower relay connector J-1 and ground.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> GO TO 2.

2.

CHECK BLOWER RELAY CONTROL SIGNAL CIRCUIT

1. Turn ignition switch OFF.

2. Disconnect BCM connector M98.

3. Check continuity between BCM connector M98 and blower relay connector J-1.

4. Check continuity between BCM connector M98 and ground.

Is the inspection result normal?

YES

>> Replace BCM. Refer to 

BCS-70, "Removal and Installation"

.

NO

>> Repair or replace harness or connectors.
