Is the inspection result normal?


Is the inspection result normal? YES >> INSPECTION END

NO >> Proceed to EC-446, "Diagnosis Procedure".

Diagnosis Procedure

1.CHECK BRAKE PEDAL POSITION SWITCH POWER SUPPLY CIRCUIT

  1. Turn ignition switch OFF.
  2. Disconnect brake pedal position switch harness connector.
  3. Turn ignition switch ON.
  4. Check the voltage between brake pedal position switch harness connector and ground.

Is the inspection result normal?


Is the inspection result normal? YES >> GO TO 3.

NO >> GO TO 2.

2.CHECK STOP LAMP SWITCH POWER SUPPLY CIRCUIT

  1. Pull out #5 fuse.
  2. Check that the fuse is not fusing.
  3. Check the continuity between stop lamp switch harness connector and fuse terminal.


  1. Also check harness for short to ground and short to power.

Is the inspection result normal? YES >> Check power supply circuit for 12V battery power supply.

NO >> Repair or replace error-detected parts.

3.CHECK BRAKE PEDAL POSITION SWITCH INPUT SIGNAL CIRCUIT

  1. Turn ignition switch OFF.
  2. Disconnect ECM harness connector.
  3. Check the continuity between brake pedal position switch harness connector and ECM harness connector.


  1. Also check harness for short to ground and short to power.

Is the inspection result normal? YES >> GO TO 4.

NO >> Repair or replace error-detected parts.

4.CHECK BRAKE PEDAL POSITION SWITCH

Check brake pedal position switch. Refer to EC-447, "Component Inspection (Brake Pedal Position Switch)" Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".

NO >> Replace brake pedal position switch. Refer to BR-22, "Exploded View".
