COMMENTS ON TROUBLE SYMPTOM

The cause is probably a faulty rear display unit
power supply circuit system.

.

PROBABLE CAUSES

• Damaged wiring harness or connector.

• Malfunction of rear display unit.

DIAGNOSIS

Required Special Tools:

• MB991223: Harness Set

• MB992006: Extra Fine Probe

• MB991958: Scan Tool (M.U.T.-III Sub Assembly)

• MB991824: Vehicle Communication Interface (V.C.I.)

• MB991827: M.U.T.-III USB Cable

• MB991910: M.U.T.-III Main Harness A

STEP 1. Using scan tool MB991958, read the ETACS-ECU
diagnostic trouble code.
Check if the diagnostic trouble code is set to the ETACS-ECU.
Q: Is the DTC set?

YES : Troubleshoot the ETACS-ECU (Refer to GROUP

54A, ETACS, Diagnosis

P.54A-733

), and then go to

Step 2.

NO : Go to Step 2.

STEP 2. Check ETACS-ECU connector C-317 and rear
display unit connector D-06 for loose, corroded or
damaged terminals, or terminals pushed back in the
connector.
Q: Is ETACS-ECU connector C-317 and rear display unit

connector D-06 in good condition?
YES : Go to Step 3.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

P.00E-2

.

STEP 3. Check the wiring harness between ETACS-ECU
connector C-317 (terminal 1) and rear display unit
connector D-06 (terminal 3).
NOTE: Also check intermediate connector D-123 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the
connector. If intermediate connector D-123 is damaged, repair
or replace the connector as described in GROUP 00E, Harness
Connector Inspection

P.00E-2

.

• Check the power supply lines (battery power supply) for

open circuit.

Q: Is the wiring harness between ETACS-ECU connector

C-317 (terminal 1) and rear display unit connector D-06
(terminal 3) 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.
Repair the wiring harness as necessary.

STEP 4. Using scan tool MB991958, check data list of
ETACS.
Check the input signal of ACC relay.

• Turn the ignition switch to the ACC position.

OK: Normal condition is displayed.

Q: Is the check result normal?

YES : Go to Step 5.
NO : Refer to Inspection Procedure 1 "The ignition switch

(ACC) signal is not received"

P.54A-787

.

STEP 5. Check ETACS-ECU connector C-309 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.
Q: Is ETACS-ECU connector C-309 in good condition?

YES : Go to Step 6.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection
