Inspection and Verification


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.
1. Verify the customer concern.
2. Visually inspect for obvious signs of damage and system integrity.

Visual Inspection
Mechanical Electrical
Bulbs
Fuses/relays (refer to electrical guide)
Wiring harness
Correct engagement of electrical connectors
Loose or corroded connections
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to
the next step.
4. If the cause is not visually evident, check for Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.

DTC Index


CAUTION: When probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit, part
number 3548-1358-00
NOTES:


If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
Warranty Policy and Procedures manual (section B1.2), or determine if any prior approval programme is in operation, prior to
the installation of a new module/component.


Generic scan tools may not read the codes listed, or may read only five digit codes. Match the five digits from the scan
tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give extra information read by
the manufacturer-approved diagnostic system).


When performing voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal places and
with a current calibration certificate. When testing resistance, always take the resistance of the DMM leads into account.


Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.


If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the
cause. Always check for loose connections and corroded terminals.

Daytime Running Lamps (DRL) - Daytime Running Lamps (DRL) - System
Operation and Component Description
Description and Operation



CENTRAL JUNCTION BOX (CJB) System Operation

The CJB (central junction box) controls the operation of the DRL (daytime running lamps). The DRL are activated once the CJB detects an ignition on power mode 6 signal.
The CJB also monitors the lighting control switch and the auto lamps feature and overrides the DRL if required.


DAYTIME RUNNING LAMPS - CANADA Component Description

The DRL for this market use full intensity low beam headlamps. The side marker lamps, tail lamps and license plate lamps will be on, but instrument cluster illumination will be off. DRL are active when the following parameters are met:
PARK is not selected on the electronic transmission selector
Electronic Parking Brake (EPB) is off
Power mode 6 (ignition on) detected by the CJB The CJB receives an engine running signal The lighting control switch is in the off or side lamps position.
NOTES:


If the lighting control switch is moved to the headlamp position, DRL are deactivated and normal side lamp and headlamp functionality is operational.


When DRL are active, the headlamp flash function using the left hand steering column multifunction switch will operate normally.

The high beam headlamp function using the left hand steering column stalk switch will be deactivated. When the transmission
is in PARK, DRL are turned off. This is to reduce battery discharge during long periods of engine idling in cold climate conditions. When the electronic transmission selector is moved from the PARK position, normal DRL functionality is restored.
DAYTIME RUNNING LAMPS - DENMARK, HOLLAND, NORWAY, SWEDEN, FINLAND AND POLAND


NOTE: DRL for Poland is on vehicles from 2008MY.

DRL for these markets use full intensity low beam headlamps. Side lamps and license plate lamps will be on, but instrument cluster illumination will be off. DRL are active when the following parameters are met:
Power mode 6 (ignition on) detected by the CJB The CJB receives an engine running signal The lighting control switch is in the off position.


NOTE: When DRL are active, the headlamp flash function using the left hand steering column multifunction switch will operate normally. The high beam headlamp function using the left hand steering column stalk switch will be deactivated.

If the lighting control switch is moved to the side lamp or headlamp positions, DRL are deactivated and normal side lamp and headlamp functionality is operational.

AUTOMATIC HEADLAMPS

On vehicles fitted with the automatic headlamps feature, DRL are overridden if the lighting control switch is in the 'Auto' position and the CJB receives a signal from the rain/light sensor to activate the exterior lights.
When the CJB receives a signal to de-activate the automatic headlamps feature the DRL function is restored providing the parameters for DRL activation are met.
