Specific warning lamp
'ON' C–1
Check with IDS for DTCs related to
identified vehicle system. . . C–2
Check for open circuit/shorts in wiring
related to warning lamp circuit (module,
sensor, switch) where appropriate. . . C–3
Perform cluster Self-Diagnostic Mode/ETM
test 3. Frost/ice warning illuminated in mixed red and
amber; therefore colour differs from other
warning lamps. When this test is ended,
warning lamps currently required to be 'ON' will
remain illuminated. . C–4
Check the specific vehicle system
indicated by the warning lamp
illuminated? What is the warning lamp telling me? Does this
check out with the DTC logged by the system indicating the fault? Fuel gauge operation D–1
Perform Self-Diagnostic Mode/ETM test 21
to establish if fuel level input to cluster is
out of range or invalid. 0 - 9 = short circuit; gauge will show empty. 10
– 254 = normal range. 255 = open circuit;
gauge will show empty. --- = missing signal; gauge will show empty. . D–2
Check gauge function versus
Self-Diagnostic Mode/ETM test 21. 0 = empty, 254 = full. 255 = invalid; gauge will
show empty. . D–3
Check for open circuit/shorts in wiring
between the Fuel Delivery Module, Jet
Pump Module and Rear Electronic Module (REM). . Fuel gauge reading E–1
Check gauge position versus
Self-Diagnostic Mode/ETM test 21. 0 = empty to 254 = full (255 invalid; gauge will
show empty). Other values percentage of above range e.g. 127 = half. . E–2
Calculate percentage fuel level from figure
obtained from Self-Diagnostic Mode/ETM
test 21 and compare to IDS vehicle fuel percentage test. Self-Diagnostic Mode fuel level percentage can
be calculated as follows: Value from
Self-Diagnostic Mode test 26 ÷ 254 x 100 = %
shown on gauge. . E–3
Monitor value of Self-Diagnostic Mode
test/ETM test 21 (during test drive) to
establish if input drops out of range. 0 - 9 = short circuit; gauge will show empty. 10
– 254 = normal range. 255 = open circuit;
gauge will show empty. --- = missing signal; gauge will show empty. . E–4
Monitor 'FUEL LEVEL' in IDS data logger
(during test drive) to correlate gauge position to vehicle reported fuel level. Gauge function is damped so will not follow
rapidly changing Fuel Delivery Module values. Speedometer
operation H–1
Monitor Self-Diagnostic Mode/ETM test 19
(during test drive) check to establish if
vehicle speed input to cluster is out of range or invalid. Display speed input in 1/10 mile/h, no decimal
point shown, and is compensated for tire size
etc. Displays ---- or INV if message is not
received or if received data is invalid. Speedometer reading I–1
During test drive compare speedometer
position to Self-Diagnostic Mode/ETM test
19, displayed value. Self-Diagnostic Mode displayed speed figure will
be approx 3% higher than speed indicated by
speedometer. Allowed tolerance – minus nothing/+ 10% + 2.5 mile/h. . I–2
Monitor Self-Diagnostic Mode/ETM test 19
(during test drive) to establish if vehicle
speed input to cluster drops out of range
or is invalid. Displays ---- if message is not received or if
received data is invalid for two seconds or more. . I–3
Check that installed wheels and tires are
standard Jaguar fitment. Confirm wheel
size in IDS, 'ADD REMOVE ACCESSORY'
section. Non standard wheels and tires may lead to
speed indication inaccuracies. Incorrectly set
wheel size will result in speed indication
inaccuracies. Trip and odometer distance
accumulation will also be incorrect. Tachometer operation J–1
Perform Self-Diagnostic Mode/ETM test 20
to establish if vehicle rpm input to cluster
out of range or invalid. Displays ---- or INV if message is not received
or if received data is invalid. Tachometer reading K–1
Check tachometer position versus
Self-Diagnostic Mode/ETM test 20, displayed value. Tachometer accuracy +/- 100 rpm. . K–2
Monitor 'ENGINE RPM' in IDS data logger
at constant engine rpm to compare
tachometer indicated engine rpm to
engine rpm reported by Engine Control
Module (ECM). Tachometer accuracy +/- 100 rpm. . K–3
Monitor Self-Diagnostic Mode test/ETM
test 20, (during test drive) to establish if
input to cluster drops out of range or is
invalid. Displays ---- or INV if message is not received
or if received data is invalid. Gauge judder L–1
Perform Self-Diagnostic Mode test/ETM
test 2, to prove out smooth gauge operation. . Gauge noise M–1
Perform vehicle road test. Gauges should
not be audible during operation in drive cycle. . www.JagDocs.com

. M–2
Benchmark noise against non-complaint
vehicle. . Trip (fuel) computer N–1
Check for consistent display (during test
drive) of valid 'Rolling Odometer' count in
Self-Diagnostic Mode/ETM test 24. Displays ---- , INV or 255 if message is not
received, or if received data is invalid. . N–2
Check that installed wheels and tires are
standard Jaguar fit. Confirm fitted wheel
size in IDS, 'ADD REMOVE ACCESSORY'
section. Non standard wheels and tires or incorrectly set
wheel size may lead to Odometer increment
inaccuracies. This will impact the distance
accumulators, which in turn affects the rolling
average, fuel economy and range values. Trip
distance accumulation will also be incorrect. . N–3
Consider noting odometer value and
resetting fuel computer system. Advise
customer to conduct brim-to-brim fuel
tank test. Use collected information to
determine if system accurate. . Column adjust O-1
Check with IDS for DTCs related to powered column system. . O-2
Check cluster battery supply voltage and
ground resistance. Check for loose
connections. . O-3
Check power column motors supply voltage. . O-4
Check power column switch for physical damage. . Passive Anti-Theft
System (PATS)
indicator P–1
Check for three second prove out when
vehicle start button is pressed. . . P–2
Check for loose connections/wiring continuity. . . P–3 Check ignition switch for physical damage. . Cluster illumination Q–1
Check for loose connections/wiring continuity. . . Q–2 Check dimmer switch operation. . Cluster backlight operation R–1
Is the backlight on other components inoperative. . . R–2 Check dimmer switch operation. . . R–3
Check for loose connections/wiring continuity. . Chime/tone operation S–1 Check vehicle configuration. . . S–2
Utilize lights ON, ignition OFF, door open warning to verify chime operation. . . S–3 Check appropriate sensing circuit. . Continuous chime/tone T–1 Check appropriate sensing circuit. . Unexpected chime operation U–1 Check vehicle configuration. . Message centre display illumination V–1
Is the backlight 'ON' and other components dim? . . V–2

related warning light trigger (module,
sensor, switch). . Cluster/connectivity Z–1 Check cluster battery and ignition wiring. . . Z–2 Check cluster grounds. . . Z–3 Disconnect/reconnect cluster. . . Z–4
Attempt to enter Self-Diagnostic
Mode/ETM to prove cluster response to inputs. . No crank AA–1
