line.

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) Connect scan tool MB991958. Refer to "How to connect the 

Scan Tool (M.U.T.-III) 

P.54A-331

."

(2) Turn the ignition switch to the "ON" position.
(3) Diagnose the CAN bus line.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the CAN bus line found to be normal?

YES : Go to Step 2.
NO :  Repair the CAN bus line. (Refer to GROUP 54C, 

Diagnosis 

P.54C-17

).

STEP 2. Using scan tool MB991958, read the other system 
DTC.
Check if the diagnostic trouble code relating to the coding error 
is set to the ETACS-ECU.
(1) Turn the ignition switch to the "ON" position.
(2) Check for DTCs.
(3) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the DTC set?

YES : Diagnose the ETACS-ECU (Refer to GROUP 54A, 

ETACS-ECU, Diagnosis 

P.54A-732

), and then go to 

Step 3.

NO :  Go to Step 3.

STEP 3. Recheck for diagnostic trouble code.
Check again if the DTC is set to the radio and CD player.
(1) Erase the DTC.
(2) Turn the ignition switch from "LOCK" (OFF) position to "ON" 

position.

(3) Check if the DTC is set.
Q: Is the DTC set?

YES : Replace the radio and CD player.
NO :  The trouble can be an intermittent malfunction (Refer 

to GROUP 00, How to use
