1. CHECK CONNECTOR
1. Turn ignition switch OFF.
2. Disconnect battery cable at negative terminal.
3. Check following terminals and connectors for damage, bend and loose connection (connector side and
harness side).
–Harness connector E116
–Harness connector M75
OK or NG
OK >> GO TO 2.
NG >> Repair terminal or connector.
2. CHECK HARNESS FOR OPEN CIRCUIT
1. Disconnect ESP/TCS/ABS control unit connector and harness connector E116.
2. Check the following.
–LHD models
Check continuity between ESP/TCS/ABS control unit harness
connector E122 terminals 61 (W), 63 (R) and harness connector
E116 terminals 14 (W), 5 (R).
–RHD models
Check continuity between ESP/TCS/ABS control unit harness
connector E122 terminals 61 (W), 63 (R) and harness connector
