INSPECTION PROCEDURE
1. CHECK SELF-DIAGNOSIS RESULTS
Check self-diagnosis 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 E50 and VDC/TCS/ABS control unit connector, check terminals for
deformation, disconnection, looseness, and so on. If there is an error, repair or replace the terminal.
2. Reconnect the connectors and then perform self-diagnosis.
Is the result of self-diagnosis normal?
YES >> The connector terminal contact is loose, damaged, open or shorted.
NO >> GO TO 3.
3. CHECK PRESSURE SENSOR HARNESS
1. Turn ignition switch OFF and disconnect Pressure sensor con-
nector E50 and VDC/TCS/ABS control unit connector E118.
2. Check continuity between VDC/TCS/ABS control unit connector
and pressure sensor connector.
OK or NG
OK >> GO TO 4.
NG >> If the open or short in harness, repair or replace the harness.
4. CHECK PRESSURE SENSOR
1. Connect pressure sensor and VDC/TCS/ABS control unit connectors.
2. Use ?DATA MONITOR? to check pressure sensor value.
OK or NG
OK >> INSPECTION END
NG >> If the pressure sensor is damaged or malfunctioning, replace the VDC actuator (pressure sensor it
built in).
