Inspection 4: Pressure Sensor Circuit
DTC C1142
INSPECTION PROCEDURE
1. CHECK SELF-DIAGNOSTIC RESULTS40c





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 and ABS actuator and electric unit (control unit) connector.
2. Check continuity between ABS actuator and electric unit (control unit) harness connector E56 and pressure sensor harness connector E53.
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.





OK or NG
OK >> INSPECTION END
NG >> Pressure sensor is damaged or malfunctioning, replace pressure sensor.
