or terminals pushed back in the connector.

Q:Is ETACS-ECU connector C-317 and WCM connector

C-29 in good condition?

YES:

Go to Step 3.

NO:

Repair the defective connector.

STEP 3. Check the wiring harness between WCM connector
C-29 (terminal No.9) and ETACS-ECU connector C-317
(terminal No.5).

｠

Check the power supply line for open circuit.

Q:Is the wiring harness between WCM connector C-29

(terminal No. 9) and ETACS-ECU connector C-317

(terminal No. 5) in good condition?

YES:

Go to Step 4.

NO:

The wiring harness may be damaged or the connector

(s) may have loose, corroded or damaged terminals, or
terminals pushed back in the connector.

STEP 4. Using scan tool MB991958, check data list.
Use the ETACS-ECU data list to check the signals related to the
ignition voltage.

DIAGNOSIS

Q:Does scan tool MB991958 display the item "IG voltage"

as normal condition?

YES:

Go to Step 5.

NO:

Diagnose the ETACS-ECU. Refer to GROUP 54Ad,

Diagnosis P.54Ad-8.

STEP 5. Recheck for diagnostic trouble code.
Check again if the DTC is set to the WCM.

(1)

Erase the DTC.

(2)

position.

(3)

Check if DTC is set.

(4)

Turn the ignition switch to the "LOCK" (OFF) position.

Q:Is the DTC set?

YES:

Replace WCM and register the ID codes. (Refer to P.

42C-8.)

NO:

The trouble can be an intermittent malfunction (Refer

to GROUP 00 - How to use Troubleshooting/inspection
Service Points - How to Cope with Intermittent
Malfunction P.00-15).
