Test
harness

Harness side: C-04

(2)

Check that there is continuity between joint connector
(CAN2) terminals 6 and 19.

OK: No continuity

Q:Is the check result normal?

YES:

Check intermediate connector C-27, and repair if

necessary. If the intermediate connector is in good
condition, repair the wiring harness between joint
connector (CAN2) C-04 and joint connector (CAN3) C-01.

NO:

Go to Step 13.

STEP 8. Using scan tool MB991958, diagnose the CAN bus
line. (checking the steering wheel sensor for internal short)

Strictly observe the specified wiring harness repair
procedure. For details refer to P.54D-8.

To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before
connecting or disconnecting scan tool MB991958.

(1)
