Component Checks

High beam headlamp switch

Pin occupation, component side:

NOTE: The value measured in the continuity test of the high beam switch should be less

headlamp with the aid of the Wiring Diagrams.
CHECK system operates correctly

H14: CHECK THE GROUND CONNECTION OF THE CORNERING LIGHT, RIGHT-HAND
HEADLAMP, FOR OPEN CIRCUIT

Ignition switch in position 0.

1

Measure the resistance between the left-hand
headlamp, connector C1LF09, pin 9, circuit

GD132X (BK/VT), wiring harness side and ground.

2

Is a resistance of less than 2 Ohms registered?
Yes

INSTALL A NEW headlamp. CHECK system operates
correctly

No

LOCATE and RECTIFY the break in corresponding
circuit GD132X (BK/VT) between soldered
connection SP380 and the headlamp using the
Wiring Diagrams. CHECK system operates correctly

H15: RULE OUT THE ADAPTIVE LIGHTING MODULE AS THE CAUSE OF THE FAULT

Ignition switch in position 0.

1

Disconnect fuse F39 (15 A) (EJB).

2

Disconnect fuse F43 (5 A) (EJB).

3

Ignition switch in position II.

4

CHECK the cornering lights.

5

Is the left-hand cornering light permanently on?
Yes

LOCATE and RECTIFY the short to battery voltage
in the circuits between the adaptive lighting module
and the left-hand headlamp with the aid of the
Wiring Diagrams. CHECK system operates correctly

No

- Right-hand cornering light permanently lit:
LOCATE and RECTIFY the short to battery voltage
in the circuits between the adaptive lighting module
and the right-hand headlamp with the aid of the
Wiring Diagrams. CHECK system operates correctly
- None of the cornering lights is permanently lit:
RENEW the adaptive front lighting module. CHECK
system operates correctly If the concern persists:

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: If a new generic electronic module (GEM) is being installed, the new module must
be configured following installation. For this purpose, the vehicle-specific data or the data
to be changed is read out of the module using WDS and is transferred to the new module.
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.
NOTE: Ensure correct locking of the wiring harness connector.
NOTE: The rain sensor module is also responsible for actuating the automatic headlamps.

1. 1. Verify the customer concern.

2. 2. Visually inspect for obvious signs of electrical (or mechanical) damage.

Visual Inspection

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

carrying out any further tests.

4. 4. If the concern is not visually evident, PERFORM a fault diagnosis on the generic

electronic module (GEM) with WDS and RECTIFY any displayed faults in accordance
with the displayed fault description. CHECK the operation of the system.

5. 5. On a vehicle without stored fault(s), continue according to the Symptom Chart and

the corresponding symptom.

6. 6. Following checking or elimination of the fault(s) and after completion of operations,

the fault memory in the generic electronic module (GEM) must be READ OUT and
any stored faults must be DELETED. After road testing and CHECKING the system,
READ OUT the fault memory again.

Mechanical

Electrical

Check the adhesive pad between the rain sensor and the windshield

for trapped air.

Clean wax residues from the windshield in the vicinity of the rain

sensor.

Check the windshield for damage/cracks in the vicinity of the rain

sensor.

Check that the rain sensor retaining frame is correctly attached to the

windshield.

Check the wiper blades for residue-free wiping in the vicinity of the

rain sensor.

PINPOINT TEST A : AUTOMATIC HEADLAMPS INOPERATIVE

TEST CONDITIONS

DETAILS/RESULTS/ACTIONS

A1: DETERMINE THE FAULT CONDITION

Ignition switch in position II.

1

SWITCH ON dipped beam.

2

CHECK the operation of the dipped beam and the
parking lamps.

3

SWITCH ON the automatic headlamps.

4

Cover rain sensor with opaque material to simulate
insufficient light conditions.

5

CHECK the operation of the dipped beam and the
parking lamps.
