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 relay box connector E47, E48, E222 and VDC/TCS/ABS control unit connector and check ter-
minals for deformation, disconnection, looseness, and so on. If there is an error, repair or replace the ter-
minal.
2. Securely reconnect the connectors and then preform 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 ACTUATOR RELAY POWER SYSTEM
1. Turn ignition switch OFF and disconnect VDC relay box connec-
tor E48.
2. Check voltage between VDC relay box connector and ground.
OK or NG
OK >> GO TO 4.
NG >> The circuit between battery and VDC relay box harness
connector E48 terminal 9 is open or shorted. Repair the
circuit.
4. CHECK ACTUATOR RELAY HARNESS
1. Disconnect VDC/TCS/ABS control unit connector E47.
2. Check continuity between VDC/TCS/ABS control unit connector
E118 and VDC relay box connector E47.
OK or NG
OK >> GO TO 5.
NG >> Open or short in harness. Repair or replace the harness.
5. CHECK ACTUATOR RELAY
Independently check VDC actuator relay. Refer to BRC-128, "
ABS MOTOR RELAY AND ACTUATOR RELAY"
.
OK or NG
OK >> Replace VDC actuator assembly.
NG >> Replace VDC relay box.
