Pressure Sensor System Inspection

FRONT PRESSURE INSPECTION PROCEDURE
1. DISPLAY SELF DIAGNOSIS RESULTS
Check self-diagnosis result display item.





Is the self-diagnosis result display item shown above displayed?
YES >> GO TO 2.
NO >> Inspection End.

2. CONNECTOR INSPECTION
1. Turn the ignition switch OFF.
2. Disconnect the front pressure sensor connector E31 and ABS actuator and electric unit (control unit) connector E125 and inspect the terminals for deformation, disconnection, looseness, or damage.
OK or NG
OK >> GO TO 3.
NG >> Repair connector.

3. FRONT PRESSURE SENSOR CIRCUIT INSPECTION
1. Measure the continuity between the ABS actuator and electric unit (control unit) harness connector E125 and front pressure sensor harness connector E31.





2. Measure the continuity between the ABS actuator and electric unit (control unit) harness connector E125 and body ground.





OK or NG
OK >> GO TO 4.
NG >> Repair or replace harness or connector.

4. FRONT PRESSURE SENSOR INSPECTION
1. Reconnect the front pressure sensor and ABS actuator and electric unit (control unit) connectors.
2. Use "DATA MONITOR" to check if the status of "PRESS SENSOR" is normal.





OK or NG
OK >> Inspection End.
NG >> Replace front pressure sensor.

REAR PRESSURE INSPECTION PROCEDURE

Check self-diagnosis result display item.





Is the self-diagnosis result display item shown above displayed?
YES >> GO TO 2.
NO >> Inspection End.

2. CONNECTOR INSPECTION
1. Turn the ignition switch OFF.
2. Disconnect the rear pressure sensor connector E32 and ABS actuator and electric unit (control unit) connector E125 and inspect the terminals for deformation, disconnection, looseness, or damage.
OK or NG
OK >> GO TO 3.
NG >> Repair connector.

3. REAR PRESSURE SENSOR CIRCUIT INSPECTION
1. Measure the continuity between the ABS actuator and electric unit (control unit) harness connector E125 and rear pressure sensor harness connector E32.





2. Measure the continuity between the ABS actuator and electric unit (control unit) harness connector E125 and body ground.





OK or NG
OK >> GO TO 4.
NG >> Repair or replace harness or connector.

4. REAR PRESSURE SENSOR INSPECTION
1. Reconnect the rear pressure sensor and ABS actuator and electric unit (control unit) connectors.
2. Use "DATA MONITOR" to check if the status of "PRESS SEN 2" is normal.





OK or NG
OK >> Inspection End.
NG >> Replace rear pressure sensor.
