STEP 9. Check ABS-ECU connector A-02 and wheel speed
sensor <front: LH> connector A-04 for loose, corroded or
damaged terminals, or terminals pushed back in the
connector.

NOTE: The special tool (Inspection test harness) MB991219
for connector pin contact pressure should be used. The test
probe should never be forcibly inserted, as it may cause a
defective contact.

Q: Are ABS-ECU connector A-02 and wheel speed sensor

<front: LH> connector A-04 damaged?
YES : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

. Then go to Step 13.

NO : Open or short circuit may be present in the front left

wheel speed sensor circuit. Repair the wiring harness
between ABS-ECU connector A-02 (terminals 5 and
16) and front left wheel speed sensor A-04 (terminals
1 and 2).Then go to Step 13.
