Jet pump fault
Fuel crossover tube blocked
or leaking
Using the manufacturer approved diagnostic system,
check datalogger signals - Fuel Sender 2 (0x61B8) -
Fuel Sender 1 (0x61B7). Refer to the table below. If
the right sensor reads empty when the left sensor
reads more than empty, check that the jet pump is
transferring fuel from the left side to the right side Fuel Gauge, Resistance, Voltage And Fuel Tank Level Comparison Chart

Use the chart to determine fuel tank fuel volume versus fuel gauge reading to determine the fuel level symptom and fault.
NOTES:

The vehicle must be parked on a level surface to obtain an accurate fuel level gauge reading.


The actual values may vary, according to the quantity of fuel in the left and right sides of the fuel tank.


An accurate fuel level gauge reading requires 3 to 5 minutes for levels to stabilise.

Removal

NOTES:


Some variation in the illustrations may occur, but the essential information is always correct.


Some illustrations may show the engine removed for clarity.

1. Depressurize the fuel system.

Refer to: Fuel System Pressure Release - V8 5.0L Petrol/V8 S/C 5.0L Petrol (310-00 Fuel System - General Information, General Procedures).
2. Refer to: Battery Disconnect and Connect (414-01 Battery, Mounting and Cables, General Procedures).


3. WARNING: Do not smoke or carry lighted tobacco or open
flame of any type when working on or near any fuel related
components. Highly flammable mixtures are always
present and may ignite. Failure to follow these instructions
may result in personal injury.
CAUTIONS:


Be prepared to collect escaping fuel.


Make sure that all openings are sealed. Use new
blanking caps.

For a detailed description of the acceleration controls, refer to the relevant Description and Operation sections in the workshop
manual. REFER to: Acceleration Control (310-02, 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 tested and/or the donor vehicle.
1. Verify the customer concern.

2. Visually inspect for obvious signs of damage and system integrity.

Accelerator pedal
Throttle body
Fuses
Wiring harness
Electrical connector(s)
Sensor(s)
Engine control module (ECM)
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 module or a component is suspect and the vehicle remains under the Manufacturers warranty, refer to the Warranty
Policy and Procedure 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 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.

Description and Operation

OVERVIEW

Speed Control

The speed control system is integrated with the engine management system and uses fueling intervention to automatically
maintain a set vehicle speed. Once engaged, the system can also be used to accelerate the vehicle without using the
accelerator pedal.
The speed control system comprises the following components:

On/Off/Suspend switch
'+' and '-' (set/accelerate and decelerate) steering wheel switches
Resume switch
Clock spring
Speed control warning indicator.
Adaptive Speed Control

The adaptive speed control system uses a forward looking radar sensor to scan the road ahead, looking for objects that are
moving at a different rate to itself. When a target is identified the adaptive speed control system will monitor the time gap
between it and the target vehicle. When that gap falls below a set driver selected level the adaptive speed control system will
intervene slowing the vehicle by backing off the throttle and/ or applying the brakes, until the correct gap is attained.
The adaptive speed control system comprises the following components:
Adaptive speed control sensor
Adaptive speed control module
Steering wheel control switches
ECM (engine control module)
Electric throttle actuator
ABS (anti-lock brake system) module and pump
Adaptive speed control warning indicator (in the instrument cluster).
