INSPECTION PROCEDURE
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 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 3.
3. 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 4.
NG >> If the open or short in harness, repair or replace harness.
4. CHECK PRESSURE SENSOR
1. Connect pressure sensor connector and ABS actuator and electric unit (control unit) connector.
2. Use CONSULT-II DATA MONITOR to check pressure sensor value.
Condition Data monitor display
When brake pedal is depressed.: Positive value
When brake pedal is released.: Approximately 0 bar
OK or NG
OK >> INSPECTION END
NG >> Pressure sensor is damaged or malfunctioning, replace pressure sensor.
