OPERATION
When a vehicle is at a standstill or being driven at a constant
speed  for  12  seconds  or  more  (except  on  rough  road),  the
headlight automatic leveling ECU inputs a headlight relay (LOW)
signal, vehicle speed signal, and height signal for judgment and
operates the headlight leveling.

NOTE: 

The automatic leveling during driving at a constant

speed operates only once after starting driving. The
automatic leveling does not work if the vehicle pitch angle
during driving at a constant speed and the vehicle pitch
angle when the vehicle is stopped are the same.

TECHNICAL DESCRIPTION (COMMENT)
Assuming that the automatic leveling DTC is not set, if neither
right nor left automatic leveling operates, the headlight automatic
leveling-ECU,  wiring  harness  and  connector(s)  between  the
headlight  automatic  leveling-ECU  and  the  headlight  relay
(LOW),  the  combination  meter  (vehicle  speed  signal
abnormality), or wiring harness and connector(s) between the
headlight  automatic  leveling-ECU  and  the  combination  meter
may have a problem.

TROUBLESHOOTING HINTS

Malfunction of the headlight automatic leveling-ECU

Malfunction of combination meter

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

DIAGNOSIS

Required Special Tools:

MB992006: Extra fine probe

MB991223: Harness set

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  (Vehicles  with
CAN communication system)

STEP 1. Using scan tool MB991958, read the diagnostic
trouble code.

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.54Ac-58."

(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 ETACS-ECU code set?

YES:

 Go to Step 2.

NO:

 Refer to Inspection Procedure 1 "Diagnostic trouble

code is not set" P.54Ac-79.

DIAGNOSIS

STEP 2. Check combination meter.

Q:Does the speedometer operate?

YES:

 Go to Step 3.

NO:

 Diagnosis the combination meter (Refer to GROUP 54Ab

- Diagnosis P.54Ab-7). On completion, go to Step 3.

STEP 3. 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 4.

NO:

 Repair the damaged parts.

STEP 4. Voltage measurement at headlight automatic
leveling-ECU connector C-110.

(1)

Disconnect  the  connector,  and  measure  at  the  wiring
harness-side connector.

(2)

Turn "ON" the headlight switch.

Connector C-110 
(Harness side)

(3)

Voltage  between  headlight  automatic  leveling-ECU
connector C-110 (terminal No. 6) and body ground

The voltage should measure approximately 12 volts
(battery positive voltage).

Q:Does the voltage measure battery voltage?

YES:

 Go to Step 6.

NO:

 Go to Step 5.

STEP 5. Check wiring harness between headlight automatic
leveling-ECU connector C-110 (terminal No. 6) and
headlight relay (LOW) connector A-28X (terminal No. 3).

Q:Are  the  wiring  harness  between  headlight  automatic

leveling-ECU  connector  C-110  (terminal  No.  6)  and

headlight relay (LOW) connector A-28X (terminal No. 3) in

good condition?

YES:

 Go to Step 6.

NO:

 Repair the wiring harness.

STEP 6. Check combination meter connector C-03 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.

Q:Is combination meter connector C-03 in good condition?

YES:

 Go to Step 7.

NO:

 Repair the damaged parts.

STEP 7. Check wiring harness between headlight automatic
leveling-ECU connector C-110 (terminal No. 9) and
combination meter connector C-03 (terminal No. 20).

NOTE: 

Prior to the wiring harness inspection, check

intermediate connector C-34, and repair if necessary.

DIAGNOSIS

Q:Are  the  wiring  harness  between  headlight  automatic

leveling-ECU  connector  C-110  (terminal  No.  9)  and

combination  meter  connector  C-03  (terminal  No.  20)  in

good condition?

YES:

 

Go to Step 8.

NO:

 Repair the wiring harness.

STEP 8. Retest the system.
Check that the automatic leveling operates normally.

Q:Is the check result normal?

YES:

 The trouble 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).

NO:

 Replace the headlight automatic leveling-ECU.

Inspection Procedure 3: Either automatic leveling does not operate.

M15410900109USA0000010000

Before  replacing  the  ECU,  ensure  that  the  power  supply
circuit, the ground circuit and the communication circuit are
normal.
