HEADLAMP LEVELLING SENSOR

CAUTIONS:

Electronic modules are sensitive to electrical charge. If exposed to these charges,

damage may result.

Be sure, that the headlamp levelling sensor is supplied with exactly 5 volts.

NOTE: Check the headlamp levelling sensor when installed.

Switch off the ignition.
Disconnect the electrical connector.
Using an external 5 volts DC supply.
Using a digital multimeter.
Using a test cable, set up the test as in the following description.

1. 1. Check headlamp levelling sensor, front/rear.

Connect the positive terminal of the voltage supply with fused cable (5 A) to pin 5 of the
headlamp levelling sensor and the negative terminal to pin 1.
To measure the voltage at the sensor, connect the positive terminal of the Digital
Multimeter to pin 4 and the negative terminal to pin 1.
Change the vehicle load during the measurement.

Measure the voltage.

Is the range of values at the digital multimeter between 2.0 - 2.7 volts?

If yes, the headlamp levelling sensor is OK.

If no, RENEW the headlamp levelling sensor.

wiring harness side.

Is a resistance of less than 2 Ohms registered?
Yes

CHECK headlamp levelling motor. CHECK the
operation of the system. If the concern persists,
RENEW the headlamp. CHECK the operation of the
system.

No

LOCATE and RECTIFY break in circuit between
right-hand headlamp and intermediate connector
C21A/B using the Wiring Diagrams. CHECK the
operation of the system.

Diagnosis and Testing

Refer to Wiring Diagrams Section 417-01, for schematic and connector
information.

Special Tool(s)

Inspection and Testing

NOTE: The generic electronic module (GEM) is part of the central junction box (CJB).
NOTE: A new GEM needs to be configured after installation. For this purpose, the vehicle-
specific data are read out of the module to be changed using WDS and is transferred to
the new module. REFER to:

Module Configuration

(418-01 Module Configuration, General Procedures),

Generic Electronic Module (GEM)

(419-10 Multifunction Electronic Modules, Diagnosis and

Testing).

NOTE: Before reading out the vehicle-specific data make sure that all electrical
connections in the vehicle are reconnected so that the module and WDS can communicate
correctly.

1. 1. Verify the customer concern.

2. 2. Visually inspect for obvious signs of electrical damage.

Visual Inspection Chart

3. 3. Resolve any obvious causes or concerns found during the visual inspection before

carrying out any further tests.

4. 4. If the cause of the concern cannot be found by visual inspection, continue with the

symptom chart.
