Diagnosis Procedure

INFOID:0000000009757865

Regarding Wiring Diagram information, refer to 

BRC-44, "Wiring Diagram"

.

NOTE:

Check brake fluid level in brake reservoir tank before starting inspection.

1.

CONNECTOR INSPECTION

1. Turn ignition switch OFF.

2. Disconnect combination meter and brake fluid level switch connectors.

3. Check connectors and terminals for deformation, disconnection, looseness or damage.
Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair or replace as necessary.

2.

CHECK BRAKE FLUID LEVEL SWITCH 

Perform the brake fluid level switch component inspection. Refer to 

BRC-84, "Component Inspection"

.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Replace brake fluid level switch. Refer to 

BR-32, "Exploded View"

.

3.

CHECK BRAKE FLUID LEVEL SWITCH HARNESS

1. Check continuity between combination meter connector M24 terminal 11 and brake fluid level switch con-

nector E40 terminal 1.

2. Check continuity between combination meter connector and ground.
