Diagnosis and Testing

Principles of Operation Published: 10-Mar-2014

For a detailed description of the battery system and operation, refer to the relevant Description and Operation section of the
workshop manual. REFER to: Battery and Cables (414-01 Battery, Mounting and Cables, Description and Operation).
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 checked and/or the donor vehicle.
NOTES:


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 additional information
read by the manufacturer-approved diagnostic system).


When performing electrical voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal
places, and with an up-to-date 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.
1. Verify the customer concern.

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

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.

5. Check DDW for open campaigns. Refer to the corresponding bulletins and SSMs which may be valid for the specific
customer complaint and carry out the recommendations as required

Generator and Regulator - V8 5.0L Petrol/V8 S/C 5.0L Petrol - Generator - Overview
Description and Operation

OVERVIEW

On 5.0L V8 vehicles (naturally aspirated and supercharger), the charging system consists of a 150 Amp output generator and
regulator assembly. The generator and regulator assembly generates electrical power for the vehicle electrical system and
maintains the battery in a charged state.

When the engine is running the generator produces an alternating current, which is converted to a direct current internally. The
output from the generator is controlled by the voltage regulator (located inside the generator) and then supplied to the battery
through the main battery positive cable. The generator is mounted on the front right side of the engine and driven at
approximately 3 times engine speed by the accessory drive belt.

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.
