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.

the RCM and illuminated by the instrument cluster on receipt of high speed CAN bus messages. The safety belt warning indicator is not subject to the 3 second indicator check when the ignition is switched on.

The operation of the passenger seat buckle switch is as described below with the exception that the instrument cluster must
receive a hardwired signal from the belt minder control module to indicate that a passenger is occupying the seat.
The safety belt warning indicator is subject to a timer. The warning indicator is activated when the following conditions exist:
Ignition is switched on
One of the front seat belts is unbuckled
USA market only - 75 seconds has elapsed after ignition on mode is selected
Vehicle is not in reverse gear
Vehicle speed is more than 8 km/h (5 mph).

Once the above parameters are met, the instrument cluster flashes the warning indicator at 2 Hz for 10 seconds accompanied
by a simultaneous chime. After 10 seconds the chime ceases and the warning indicator is permanently illuminated for 20
seconds. This sequence is repeated every 30 seconds until one of the following events occurs:
300 seconds has elapsed
The safety belt of the occupied front seats is fastened
The ignition is switched to off mode
The vehicle speed decreases to below 5 km/h (3 mph).


NOTE: On USA market vehicles, the warning indicator in not permanently illuminated.

The safety belt minder function cannot be disabled. The seat belt minder function can be disabled.
Refer to: Safety Belt System (501-20A Safety Belt System, Description and Operation). 14. Side Lamp Indicator

The instrument cluster controls the green colored side lamp indicator on receipt of a side lamp status message on the medium
speed CAN bus from the CJB and the auxiliary junction box. The lighting switch on the LH steering column multifunction switch is connected to the instrument cluster. Selections using this switch are detected by the cluster which requests the side or
headlamp operation via a message to the CJB and the RJB. The CJB and the RJB responds with a side lamp active message and the cluster illuminates the side lamp indicator. The side lamp indicator is not subject to the 3 second indicator check when
the ignition is switched on.
15. High Beam Indicator

The instrument cluster controls the blue colored high beam indicator on receipt of a high beam status message on the medium
speed CAN bus from the CJB. The lighting switch on the LH steering column multifunction switch is connected to the instrument cluster. High beam or flash selections using this switch are detected by the cluster which requests the light
operation via a CAN message to the CJB. The CJB responds with a high beam active message and the cluster illuminates the high beam indicator. The high beam indicator is not subject to the 3 second indicator check when the ignition is switched on.
16. Rear Fog Lamp Indicator

The amber colored rear fog lamp indicator is controlled by the auxiliary junction box and illuminated by the instrument cluster
on receipt of a rear fog lamp on message on the medium speed CAN bus from the RJB. The indicator is illuminated for as long as the rear fog lamps are active. The rear fog lamp indicator is not subject to the 3 second indicator check when the ignition is
switched on.

SPEEDOMETER

The speedometer is driven by high speed CAN signals transmitted by the ABS module. The wheel speeds are measured by sensors reading the rotational speed of the rear wheels from toothed targets on the hubs. An average of the two wheel speeds
are passed from the sensors to the ABS module in the form of pulsed signals. The ABS module converts these signals into a speed output on the high speed CAN to the instrument cluster. The same speed outputs from the wheel speed sensors are also used to calculate the distance the vehicle has travelled.

TACHOMETER

The tachometer is driven by an engine speed signal transmitted on the high speed CAN from the ECM. The signal is derived from the CKP (crankshaft position) sensor. The signal is received by the instrument cluster microprocessor and the output from
the microprocessor drives the tachometer.

FUEL GAGE

The fuel gage is controlled by CAN messages from the RJB. The RJB reads the values output by the fuel level sensors every 131 ms and transmits a fuel tank contents value, corrected for battery voltage, in a CAN message to the instrument cluster. A fuel pump symbol is displayed to the left of the linear gage. An arrow above the symbol shows the driver on which side of the
vehicle the fuel filler cap is located. Above the linear fuel gage, is a LCD (liquid crystal display) area which displays odometer
and trip readouts. When a trip computer function is selected, these are replaced by a trip computer display for the trip function
selected.

LIQUID CRYSTAL DISPLAY

In the area above and below the message center is a LCD display. The area below the message center displays a linear fuel www.JagDocs.com
