loose, corroded or damaged terminals, or terminals pushed
back in the connector.

Q:Are rear height sensor connector D-118 and 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 rear height
sensor connector D-118 (terminal No. 1/3) and headlight
automatic leveling-ECU connector C-110 (terminal No.
16/20).

NOTE:

Before the wiring harness check, check the

intermediate connectors C-129 and D-117, and then repair
that if necessary.

Q:Is wiring harness between rear height sensor connector

D-118 (terminal No. 1/3) and the headlight automatic

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

condition?

YES:

Go to Step 6.

NO:

Repair the wiring harness.

STEP 6. Using scan tool MB991958, Check whether the
diagnostic trouble code is reset.

(1)

Turn the ignition switch to the "ON" position.

(2)

Erase the DTC.

(3)

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

(4)

Check if DTC is set.

Q:Is DTC 23 set?

YES:

Go to Step 7.

NO:

The trouble, such as a poor connector connection from

the rear 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.)

STEP 7. Check front height sensor.
Check that the front height sensor is normal (Refer to P.
54Ac-180).

Q:Do front height sensor work normal?

YES:

Go to Step 8.

NO:

Replace the front height sensor.

STEP 8. Using scan tool MB991958, Check whether the
diagnostic trouble code is reset.

(1)

Turn the ignition switch to the "ON" position.

(2)

Erase the DTC.

(3)

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

(4)

Check if DTC is set.

TROUBLE JUDGMENT
The headlight automatic leveling-ECU receives a
vehicle height signal from the front and rear height
sensors and calculates the headlight leveling pitch
angle. If an abnormal pitch angle is calculated, DTC
24 is set.

TECHNICAL DESCRIPTION (COMMENT)
The front height sensor, the rear height sensor or the
headlight automatic leveling-ECU may have a
problem.
