1.
Load the Approved Jaguar Diagno stic System with power train
data logger.
2. Connect the Approved Jaguar Diag nostic System to the vehicle.

3. W
ith 'Disable Network Integrity Test - YES/ NO' displayed on
the screen select YES.
4. With new menu displayed on the screen, select ' Engine
Management'.
5. Turn the ignition to ON.
R
emove any previously selected data logger parameters.
6. On data logger select PPS11 an d PPS2 (Pedal demand sensors
1 and 2).
7. On Sedan models only, remove the bulkhead covers on both
sides and the engine compartment rear cover.
8. Cut, remove and discard the ra tchet strap which retains the
throttle cable to the abutment bracket.
9. Ensure there is no tension on the throttle cable by releasing
the throttle cable adjustment nut from the abutment bracket.
10. Record the voltages for both sensors, PPS11 and PPS2.
11. Partially insert the throttle cable adjustment nut into the
abutment bracket.
12. Recheck the voltages for both sensors, PPS11 and PPS2.
13. Where the voltages at step 12 are higher than the voltages
taken at step 10, contin ue to step 15 below.
14. Where the voltages at step 12 are the same as the voltages
taken at step 10, contin ue to step 16 below.
15. Rotate the adjustment nut clockwise (as viewed from the
front of the vehicle) until the same voltages are indicated as in
step 10. Continue to turn thro ugh a part revolution until the
sides of the nut are vertical. Tu rn through a further 90 degrees,
then fully insert the nut into the abutment bracket.
16. Rotate the adjustment nut anti-clockwise (as viewed from the
front of the vehicle) until the indicated voltage starts to
increase. Then rotate the nut clockwise through a part
revolution until the sides are ve rtical. Turn through a further 90
degrees, then fully insert the nut into the abutment bracket.
17. Fit a new ratchet strap to secure the throttle cable adjusting
nut to the abutment bracket.
18. Operate the throttle pedal through 20 full cycles to settle the
cable. Check the voltages now shown, remain the same as in
steps 15 and 16.
19. Check and where necessary adjust the kickdown switch. For

ciples of operation
The s
p
eed (cruise) control sy
stem is activated by an ON/OFF master switch in the J-gate surround, which has an integral
LED to indicate status.
The steering wheel switches allow the driver to set the speed, increase or decrease the selected speed, cancel and resume
the facility without his/her hand ever leaving the steering wheel
The vehicle speed can be increased an d decreased in increments of 2 kmh (1 mph) by briefly pressing the + or - buttons up
to a maximum of five times.
Alternatively, the + or - button can be held until th e desired speed is reached.
The selected speed (by whichever method) w ill be displayed in the message center.
The system will not function at speeds below 26 kmh (16 mph), and can be cancelled from the master switch, the steering
wheel switches, and by depressing th e brake pedal. The system can be overridden by accelerating as normal.
In
spection and Verification
1.
1. Veri fy the customer concern.
2. 2. Vis
ually inspect for obvious signs of mechanical or electrical damage.
3. 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. 4. If the cause is not visually evident, verify the symptom, check for DTCs and follow the routines in this section.
