ignition  switch  to  the  "LOCK"  (OFF)  position  before
connecting or disconnecting scan tool MB991958.

(1)

Connect scan tool MB991958. Refer to "How to connect scan
tool (M.U.T.-III) P.54Ac-11."

(2)

Turn the ignition switch to the "ON" position.

(3)

Check whether the ETACS-ECU DTC is set.

(4)

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

Q:Is the DTC set?

YES:

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

Diagnosis P.54Ad-8).

NO:

 Go to Step 2.

STEP 2. Using scan tool MB991958, check data list.
Using the ETACS-ECU service data, check the signals related
to the illumination of turn-signal light.
