DIAGNOSIS

TSB Revision

CONTROLLER AREA NETWORK (CAN)

54C-79

(3) Measure the voltage between joint connector (CAN3) 

terminal 5 and body ground.

OK: 4.7 volts or less

(4) Measure the voltage between joint connector (CAN3) 

terminal 16 and body ground.

OK: 4.7 volts or less

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

YES : Check intermediate connector A-13, and repair if 

necessary. If the intermediate connector is in good 
condition, repair the wiring harness between joint 
connector (CAN3) C-127 and joint connector (CAN4) 
A-14.

NO :  Check intermediate connector C-131, and repair if 

necessary. If the intermediate connector is in good 
condition, repair the wiring harness between joint 
connector (CAN3) C-127 and joint connector (CAN2) 
C-104.

STEP 10. Using scan tool MB991958, diagnose the CAN 
bus line. (checking the steering wheel sensor for internal 
short to ground)

CAUTION

Strictly observe the specified wiring harness repair proce-
dure. For details refer to 

P.54C-7

.

CAUTION

To prevent damage to scan tool MB991958, always turn the 
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(1) Disconnect ETACS-ECU connector C-301.

(2) Connect scan tool MB991958 to the data link connector.
(3) Turn the ignition switch to the "ON" position.

(4) Diagnose CAN bus lines, and check if the scan tool 

MB991958 screen is as shown in the figure.

OK: The display of the scan tool MB991958 is as 
shown in the figure.

Q: Does scan tool MB991958 screen correspond to the 

illustration?
YES : 
Repair the wiring harness between steering wheel 

sensor connector C-209 and joint connector (CAN2) 
C-104.

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.
