C1155 BRAKE FLUID LEVEL SWITCH

Description

INFOID:0000000003247198

The brake fluid level switch converts the brake fluid level to an electric signal and transmits it to the ABS actu-
ator and electric unit (control unit).

CHECK BRAKE WARNING LAMP 1

Check that the brake warning lamp illuminates after the ignition switch is turned ON.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Check wiring to brake fluid level switch.

3.

CHECK BRAKE WARNING LAMP 2

Check that the brake warning lamp in the combination meter turns ON/OFF correctly when operating the park-
ing brake.
Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Check parking brake switch.

4.

CHECK CONNECTOR

1.

Turn the ignition switch OFF.

2.

Disconnect brake fluid level switch connector and combination meter connector.

3.

Check terminal for deformation, disconnection, looseness, etc.

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> Replace or repair damaged parts.

5.

CHECK BRAKE FLUID LEVEL SWITCH

Check brake fluid level switch. Refer to 

BRC-70, "Component Inspection"

.

Is the inspection result normal?

CHECK BRAKE FLUID LEVEL SWITCH CIRCUIT

1.

Check the continuity between brake fluid level switch harness connector and combination meter harness
connector.

2.

Check the continuity between brake fluid level switch harness connector and ground.

Is the inspection result normal?

YES

>> Replace ABS actuator and electric unit (control unit).

NO

>> Repair or replace damaged parts.
