STEP 6. Check the wiring harness between joint connector
(CAN3) C-01 and TCM connector C-38 for a short to power
supply. Measure the voltage at joint connector (CAN3) C-01.

(1)

Disconnect joint connector (CAN3), and measure the voltage
at the wiring harness side of joint connector (CAN3).

(2)

Turn the ignition switch to the ON position.

ZC5010400012

Harness side: C-01

Test harness

(3)

Measure  the  voltage  between  joint  connector  (CAN3)
terminal 7 and body ground.

OK: 4.7 volts or less

Harness side: C-01

Test 
harness

(4)

Measure  the  voltage  between  joint  connector  (CAN3)
terminal 20 and body ground.

OK: 4.7 volts or less

Q:Do all the voltages measure 4.7 volts or less?

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 12.

STEP 7. Using scan tool MB991958, diagnose the CAN bus
line. (checking the steering wheel sensor for internal short
to ground)

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.

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

STEP 8. Using scan tool MB991958, diagnose the CAN bus
line. (checking the AWD-ECU for internal short to ground)

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

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