4.CHECK BRAKE FLUID LEVEL SWITCH CIRCUIT

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

   Combination meter | Brake fluid level switch | Continuity
   Connector | Terminal | Connector | Terminal
   M53 | 32 | E47 | 1 | Existed

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

   Brake fluid level switch | — | Continuity
   Connector | Terminal
   E47 | 2 | Ground | Existed

3. Check the continuity between combination meter harness connector and ground.

   Combination meter | — | Continuity
   Connector | Terminal
   M53 | 32 | Ground | Not existed

4. Check the continuity between the ABS actuator and electric unit (control unit) harness connector and brake fluid level switch harness connector.

   ABS actuator and electric unit (control unit) | Brake fluid level switch | Continuity
   Connector | Terminal | Connector | Terminal
   E41 | 38 | E47 | 1 | Existed

Is the inspection result normal?
YES>>Replace combination meter. Refer to Exploded View.
NO>>Repair or replace error-detected parts.
