YES - Proceed to diagnosis procedure. SEE Diagnosis Procedure.
NO - INSPECTION END




Diagnosis Procedure
1.CHECK STOP LAMP FOR ILLUMINATION
Depress brake pedal and check that stop lamp turns ON.
Does stop lamp turn ON?
YES - GO TO 2.
NO - Check stop lamp system. Exterior Lighting System.
2.CHECK STOP LAMP SWITCH CIRCUIT (1)
1. Turn the ignition switch OFF.
2. Disconnect ABS actuator and electric unit (control unit) harness connector.
3. Check voltage between ABS actuator and electric unit (control unit) harness connector and ground.





4. Turn the ignition switch ON.
5. Check voltage between ABS actuator and electric unit (control unit) harness connector and ground.





Is the inspection result normal?
YES - GO TO 5.
NO - GO TO 3.
3.CHECK STOP LAMP SWITCH CIRCUIT (2)
1. Turn the ignition switch OFF.
2. Disconnect stop lamp switch harness connector.
3. Check continuity between ABS actuator and electric unit (control unit) harness connector and stop lamp switch harness connector.





*1: Models without ICC system
*2: Models with ICC system
4. Disconnect resistor harness connector. (Models with ICC system)
5. Check continuity between ABS actuator and electric unit (control unit) harness connector and resistor harness connector. (Models with ICC system)





6. Check continuity between ABS actuator and electric unit (control unit) harness connector and the ground.





7. Check continuity resistor harness connector and ground.





Is the inspection result normal?
YES - GO TO 4.
NO - Repair or replace error-detected parts.
4.CHECK STOP LAMP SWITCH CIRCUIT (3)
1. Disconnect fuse block (J/B) harness connector.
2. Check fuse block (J/B) pin terminals for damage or loose connection with harness connector.
3. Check continuity between stop lamp switch harness connector and fuse block (J/B).





*1: Models without ICC system
*2: Models with ICC system
