1.CHECK SELF-DIAGNOSTIC RESULTS
Check the self-diagnostic results.
Is the above displayed in the self-diagnosis display items?
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, check terminals for deformation, disconnection, looseness, and so on. If any malfunction is found, repair or replace terminal.
2. Reconnect connectors and perform ABS actuator and electric unit (control unit) self-diagnosis again.
OK or NG
OK >> Connector terminal contact is loose, damaged, open or shorted.
NG >> GO TO 3.
3.CHECK STOP LAMP SWITCH
1. Turn ignition switch OFF and disconnect stop lamp switch harness connector.
2. Operate stop lamp switch and check continuity between stop lamp switch harness connector terminals.
OK or NG
OK >> GO TO 4.
NG >> Replace stop lamp switch.
4.CHECK STOP LAMP SWITCH CIRCUIT
1. Turn ignition switch OFF and disconnect stop lamp switch connector E210 and ABS actuator and electric unit (control unit) connector E56.
2. 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 CONNECTOR
1. Disconnect pressure sensor connector and ABS actuator and electric unit (control unit) connector, check terminals for deformation, disconnection, looseness, and so on. If any malfunction is found, repair or replace terminal.
2. Reconnect connectors and perform ABS actuator and electric unit (control unit) self-diagnosis again.
OK or NG
OK >> Connector terminal contact is loose, damaged, open or shorted.
NG >> GO TO 6.
6.CHECK PRESSURE SENSOR HARNESS
1. Turn ignition switch OFF and disconnect pressure sensor connector E53 and ABS actuator and electric unit (control unit) connector E56.
2. Check continuity between ABS actuator and electric unit (control unit) harness connector and pressure sensor harness connector.
OK or NG
OK >> GO TO 7.
NG >> If the open or short in harness, repair or replace harness.
7.CHECK PRESSURE SENSOR
1. Connect pressure sensor connector and 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 >> Pressure sensor is damaged or malfunctioning, replace pressure sensor.
