position.

(5)

Check if DTC is set.

Q:Is DTC 22 set?

YES:

 Go to Step 4.

NO:

 The procedure is complete.

STEP 4. Check headlight automatic leveling-ECU connector
C-110 for loose, corroded or damaged terminals, or
terminals pushed back in the connector.

Q:Is headlight automatic leveling-ECU connector C-110 in

good condition?

YES:

 Go to Step 5.

NO:

 Repair the damaged parts.

STEP 5. Check the wiring harness between front height
sensor connector A-04 (terminal No. 1/2/3) and the headlight
automatic leveling-ECU connector C-110 (terminal No.
15/17/19).

NOTE: 

Before the wiring harness check, check the

intermediate connector A-57, and repair that if necessary.

Q:Is wiring harness between front height sensor connector

A-04  (terminal  No.  1/2/3)  and  the  headlight  automatic

leveling-ECU connector C-110 (terminal No 15/17/19) in

good condition?

YES:

 Go to Step 6.

NO:

 Repair the wiring harness.

STEP 6. Using scan tool MB991958, Check whether the

DIAGNOSIS

YES:

 Replace the headlight automatic leveling-ECU.

NO:

 The trouble, such as a poor connector connection from

the front height sensor to headlight automatic leveling-
ECU or an open circuit of wiring harness, 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.)

DTC 23: Height sensor power supply short to ground

TROUBLE JUDGMENT
If  the  front  height  sensor,  rear  height  sensor  power
supply, or ground line is short-circuited, DTC 23 is set.

TECHNICAL DESCRIPTION (COMMENT)
The front height sensor, the rear height sensor, the
headlight automatic leveling-ECU, or wiring harness
and connectors between the front/rear height sensor
and the headlight automatic leveling-ECU may have
a problem.

TROUBLESHOOTING HINTS

Malfunction of the front height sensor

Malfunction of the rear height sensor

Malfunction  of  the  headlight  automatic  leveling-
ECU

The wiring harness or connectors may have loose,
corroded,  or  damaged  terminals,  or  terminals
pushed back in the connector

DIAGNOSIS

Required Special Tools:

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

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

MB991827: M.U.T.-III USB Cable

DIAGNOSIS

MB991910:  M.U.T.-III  Main  Harness  A  (Vehicles  with
CAN communication system)

STEP 1. Check front height sensor connector A-04 and
headlight automatic leveling-ECU connector D-110 for
loose, corroded or damaged terminals, or terminals pushed
back in the connector.

Q:Are  front  height  sensor  connector  A-04  and  headlight

automatic  leveling-ECU  connector  D-110  in  good

condition?

YES:

 Go to Step 2.

NO:

 Repair the damaged parts.

STEP 2. Check the wiring harness between front height
sensor connector A-04 (terminal No. 1/3) and headlight
automatic leveling-ECU connector D-110 (terminal No.
15/19).

NOTE: 

Before the wiring harness check, check the

intermediate connector A-57, and repair that if necessary.

Q:Is wiring harness between front height sensor connector

A-04 (terminal No. 1/3) and headlight automatic leveling-

ECU  connector  D-110  (terminal  No.  15/19)  in  good

condition?

YES:
