VDC/TCS/ABS Control Unit Branch Line CircuitNKS0054P
INSPECTION PROCEDURE
1. CHECK CONNECTOR
1. Turn the ignition switch OFF.
2. Disconnect the battery cable from the negative terminal.
3. Check the following terminals and connectors for damage, bend and loose connection (unit side and con-
nector side).
–VDC/TCS/ABS control unit connector
–Harness connector B101
–Harness connector M73
OK or NG
OK >> GO TO 2.
NG >> Repair the terminal and connector.
2. CHECK HARNESS FOR OPEN CIRCUIT
1. Disconnect the connector of VDC/TCS/ABS control unit.
2. Check the resistance between the VDC/TCS/ABS control unit harness connector terminals.
OK or NG
OK >> GO TO 3.
NG >> Repair the VDC/TCS/ABS control unit branch line.
3. CHECK POWER SUPPLY AND GROUND CIRCUIT
Check the power supply and the ground circuit of the VDC/TCS/ABS control unit. Refer to BRC-87, "
Wiring
Diagram — VDC —" .
OK or NG
OK >>
Present error: Replace the VDC/TCS/ABS control unit. Refer to BRC-129, "Removal and Instal-
lation" .

Past error: Error was detected in the VDC/TCS/ABS control unit branch line.
NG >> Repair the power supply and the ground circuit.
