line short. Measure the resistance at joint connector (CAN2)
C-04.

(1)

Disconnect joint connector (CAN2), and check that there is
continuity at the harness side of joint connector (CAN2).

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)

Disconnect steering wheel sensor connector C-209.

YES:

 Repair the wiring harness between steering wheel

sensor connector C-209 and joint connector (CAN2) C-04.

NO:

 Check steering wheel sensor connector C-209, and

repair if necessary. If the steering wheel sensor
connector is in good condition, replace the steering
wheel sensor.

STEP 9. Using scan tool MB991958, diagnose the CAN bus
line. (checking the AWD-ECU for internal short)

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

necessary. If the intermediate connector is in good
condition, repair the wiring harness between AWD-ECU
connector C-128 and joint connector (CAN2) C-04.

NO:

 Check AWD-ECU connector C-128, and repair if

necessary. If the AWD-ECU connector is in good condition,
replace the AWD-ECU.

STEP 10. Using scan tool MB991958, diagnose the CAN bus
line. (checking the ECM for internal short)
