Component Function Check
1.CHECK BRAKE PEDAL POSITION SWITCH FUNCTION
With CONSULT
- Turn ignition switch ON.
- Select “ENGINE” using CONSULT.
- Select “BRAKE SW1” in “DATA MONITOR” mode.
- Check “BRAKE SW1” indication under the following conditions.
Without CONSULT
- Turn ignition switch ON.
- Check the voltage between ECM harness connector terminals under the following conditions.
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
- Turn ignition switch OFF.
- Disconnect brake pedal position switch harness connector.
- Turn ignition switch ON.
- Check the voltage between brake pedal position switch harness connector and ground.
Is the inspection result normal? YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK STOP LAMP SWITCH POWER SUPPLY CIRCUIT
- Pull out #5 fuse.
- Check that the fuse is not fusing.
- Check the continuity between stop lamp switch harness connector and fuse terminal.
- 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
- Turn ignition switch OFF.
- Disconnect ECM harness connector.
- Check the continuity between brake pedal position switch harness connector and ECM harness connector.
- 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".
Component Inspection (Brake Pedal Position Switch)
1.CHECK BRAKE PEDAL POSITION SWITCH-I
- Turn ignition switch OFF.
- Disconnect brake pedal position switch harness connector.
- Check the continuity between brake pedal position switch terminals under the following conditions.
Is the inspection result normal? YES >> INSPECTION END
NO >> GO TO 2.
2.CHECK BRAKE PEDAL POSITION SWITCH-II
- Adjust brake pedal position switch installation. Refer to BR-15, "Adjustment".
- Check the continuity between brake pedal position switch terminals under the following conditions.
Is the inspection result normal? YES >> INSPECTION END
NO >> Replace brake pedal position switch. Refer to BR-22, "Exploded View".
