Item Description 1 Speedometer 2 ABS indicator (NAS) 3 ABS indicator (ROW) 4 Adaptive speed control indicator 5 Tachometer 6 Malfunction Indicator Lamp (MIL) 7 Tire Pressure Monitoring System (TPMS) indicator 8 Airbag warning indicator 9 Front fog lamp indicator 10 RH turn signal indicator 11 Rear fog lamp indicator 12 Dynamic Stability Control (DSC) indicator 13 High beam indicator 14 Seat belt warning indicator 15 Side lamp indicator 16 Message center 17 Automatic Speed Limiter (ASL) indicator 18 Forward alert indicator 19 Brake warning indicator (NAS) 20 Brake warning indicator (ROW) 21 LH turn signal indicator The warning indicators are located in various positions in the instrument cluster. The indicators can be split into two groups;
instrument cluster controlled and externally controlled.

Instrument cluster controlled warning indicators are dependent on software logic within the instrument cluster for activation.
The cluster software controls the indicator illumination check at ignition on (power mode 6).

Externally controlled indicators are supplied with current from another vehicle system control module or illuminated by the
instrument cluster software on receipt of a bus message from another vehicle sub-system. The indicator illumination check at
ignition on (powermode 6) is also controlled by the sub-system module for these indicators.

MESSAGE CENTER

The message center is a LCD located in a central position in the cluster. The message center displays system status information.
Refer to: Information and Message Center (413-08 Information and Message Center, Description and Operation).
ANALOGUE GAGES

Speedometer
The analogue speedometer is located on the LH side of the instrument cluster and is available in 4 market variants: Major scale Miles Per Hour (MPH), minor scale kilometers per hour (km/h) (ROW)
Major scale MPH, minor scale km/h (NAS)
Major scale km/h, minor scale MPH
Major scale km/h only.
Tachometer

The analogue tachometer is located on the RH side of the instrument cluster. The tachometer has different Revolutions Per Minute (RPM) scales depending on the engine variant fitted to the vehicle as follows:

4.2L V8 Naturally aspirated 8000 RPM (NAS Only)
5.0L V8 Naturally aspirated 8000 RPM
5.0L V8 Supercharger 8000 RPM
3.0L V6 Naturally aspirated 8000 RPM
3.0 V6 Diesel 6000 RPM.

ELECTRONIC GAGES

Fuel Gage

The linear fuel gage has a colored bar which moves left or right depending on the tank contents. As the bar moves to the left
the fuel tank contents displayed is decreasing. A warning message is displayed in the message center when the fuel tank
contents fall to below the reserve level.
Transmission Gear Position Display

The gear position display shows the JaguarDrive selector position or the selected gear when using the Jaguar Sequential Shift.
The applicable drive letter is highlighted to show that a selection has been made using the JaguarDrive selector.
When Jaguar Sequential Shift is selected, the letters change to numbers; 1 - 6, and the selected gear is highlighted to
emphasize the selection to the driver.

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.

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, verify the symptom and refer to the Symptom Chart.

Symptom Chart

The instrument cluster contains a self-diagnostic mode known as engineering test mode (ETM). This can be used to show the
status of the instrument cluster inputs as well as a number of other useful features.

When in the ETM, the Message Centre displays internal data that can be cycled through. All functions except the message
centre display will continue to operate normally unless otherwise noted.

This document is to be used in conjunction with the instrument cluster ETM (see relevant section within this document) and
the Integrated Diagnostic System (IDS) facility; this does not supersede or replace the IDS facility.

Go directly to the 'Area of Concern/Symptom' that indicates the customer concern(s) and perform the actions described within
the relevant section(s):

1. If the cause is not visually evident, verify the symptom and refer to the Self-Diagnostic Mode

Self-Diagnostic Mode

To place the cluster in engineering test mode (ETM) carry out the following steps

1. Press and hold the stalk trip cycle button, for more than five seconds but less than eight seconds, whilst briefly pressing the
vehicle START button. There is no initial display indication that the instrument cluster has entered ETM. If ETM has successfully
been entered then 'ENGINEERING TEST MODE' will be displayed in the Message Centre when the stalk trip button is released .
2. To navigate forward through the instrument cluster Self-Diagnostic Mode tests, press the stalk trip cycle button.

3. Each push of the stalk trip cycle button will advance one step through the ETM sequence. It is not possible to move
backward through the test sequence.
4. To exit the Self-Diagnostic Mode press and hold the stalk trip cycle button for more than three seconds.

5. The Self-Diagnostic Mode is also deactivated when the ignigition switch is turned to the 'OFF' position or low battery voltage
is detected.
6. If the Self-Diagnostic Mode cannot be accessed repeat the above paying particular care to the sequence timing.
7. The ETM text is not language configurable and will be displayed in English.

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.
