1. CHECK SELF-DIAGNOSTIC RESULTS
Check self-diagnosis results.





Is above displayed on the self-diagnosis display?
YES >> GO TO 2.
NO >> INSPECTION END

2. CHECK STOP LAMP SWITCH CONNECTOR
1. Disconnect stop lamp switch connector and ABS actuator and electric unit (control unit) connector.

NG >> Replace stop lamp switch.

4. CHECK STOP LAMP SWITCH CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect stop lamp switch connector E124 and ABS actuator and electric unit (control unit) connector E30.
3. Check continuity between stop lamp switch harness connector and ABS actuator and electric unit (control unit) harness connector.





OK or NG
OK >> GO TO 5.
NG >> Open or short in harness between stop lamp switch and ABS actuator and electric unit (control unit). Repair or replace applied harness.

5. CHECK PRESSURE SENSOR
1. Connect ABS actuator and electric unit (control unit) connector.
2. Perform "DATA MONITOR" of the "PRESS SENSOR" to check if the status is normal.





OK or NG
OK >> INSPECTION END
NG >> If the pressure sensor is damaged or malfunctioning, replace the ABS actuator and electric unit (control unit).
