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)

Connect scan tool MB991958. Refer to "How to connect scan
too (M.U.T.-III) P.54Af-4."

(2)

Turn the ignition switch to the "ON" position.

(3)

Check whether the ETACS-ECU related 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.
Use the ETACS-ECU data list to check the signals related to the
ignition key cylinder illumination light function.

｠

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

Diagnosis - Inspection Procedure 3 "ETACS-ECU does not
receive any signal from key reminder switch" P.54Ad-64.

STEP 3. Check key reminder switch connector C-211,
ETACS-ECU connector C-315 for loose, corroded or
damaged terminals, or terminals pushed back in the
connector.

Q:Is  key  reminder  switch  connector  C-211,  ETACS-ECU

connector C-315 in good condition?

YES:

 Go to Step 4.

NO:

 Repair the damaged parts.

STEP 4.Check the Wiring harness between key reminder
switch connector C-211 (terminal No. 3,5) and ETACS-ECU
connector C-315 (terminal No. 13,18).

｠

Check the input/output line for open circuit.

Q:Is the check result normal?

YES:

 Go to Step 5.

NO:

 Repair the wiring harness between key reminder switch

connector C-211 and ETACS-ECU connector C-315.

STEP 5. Check of ignition key cylinder illumination light
bulb.
