Procedure

Before proceeding with this workshop procedure check the VCATS label to ensure that corrective action has not already been carried out.

Ensure that an interior protection kit is fitted in the vehicle.

* If the installation of an Instrument Pack is required, refer to JTIS section 413-01 SRO 88.20.24 for XK vehicles, 501-12 for XJ vehicles, but do not remove the airbag and steering wheel.*

^ Make a copy of the Odometer Disclosure Statement.

^ USA dealers: Fill out the Odometer Disclosure Statement completely and fax it with the repair order to the JNA Parts Department (201-818-9816).

^ Canada dealers: Contact the Jaguar Canada Parts Department (905) 792-9400 ext. 248. Do not order the instrument pack directly from the Bramalea warehouse. This will be carried out on your behalf prior to shipment to the US for metrage programming. MPH instrument packs will not be supplied for Canadian market vehicles.

1. Adjust steering column to fully extended and lowered position.

2. Before disconnecting the battery, note customer preferences such as sport mode switch, cruise control, clock settings, radio settings, etc.

3. Remove battery cover and disconnect ground cable from battery terminal. Refer to technical bulletin 414-01.

4. Remove Instrument Pack (Major Gauge Module - JTIS section 413-01 SRO 88.20.24).

5. Place anti static mat (such as Radio Shack part no. RSU 11519428 or Techni-Tool 780ST8505) on the work bench and connect the wrist strap.

Caution:
Ensure anti static mat is clean so as not to damage the instrument pack lens.

6. Place instrument pack on mat face down - use care not to damage the lens.

7. Undo and remove module back plate securing screws. (Torx T20)

8. Displace back plate using hinge action on paper adhesive label and place aside - careful not to rip the label.

9. Carefully remove back plate from the paper adhesive label and place aside - do not rip the label.





10. Examine circuit board to determine if rework to solder area is required. (Refer to Illustrations 1 - 4).





Illustration 2 shows an acceptable circuit board. This board does not require rework.





Illustration 3 shows a borderline case. This circuit board does not require rework.





Illustration 4 shows an unacceptable case. This circuit board requires rework If rework of the solder area is required (Illustration 4) proceed to step 11. If no rework is required proceed to step 14.

Caution:
Do not use the craft knife in a downward cutting action across the board. This Will damage the board. Cut at an angle ensuring that only the solder is cut through. Ensure all traces of cut solder are removed and discarded. Do not leave any solder particles. This could cause further contamination to the board. Do not remove solder from other areas of the circuit board, only those identified in this Service Action.





11. Using a sharp craft knife, raise and fold back any solder that has spread beyond the borderline area, as shown in illustration 5

12. Using a sharp craft knife, cut off the raised solder segments. See illustration 5.

13. Using a continuity meter, check there are no shorts between test point 1 and the two adjacent solder points 2 and 3 as shown in Illustration 5.

Caution:
During the test operation in step 13, if a short is present, repeat solder removal operation.

Once no shorts are present and the rework is complete proceed to step 14 of the procedure.

14. Position and seat the new supplied module back plate. (Modified back plate has relieved screw boss).

Note:
Do not trap paper adhesive label during the previous step.





Note:
The supplied modified back plate is identified by an "M" mark on the outer face, this will inform future workshops that the back plate has been replaced (Illustration 6).

15. Fit and tighten back plate securing screws. (Torque 0.5 - 0.8 Newton meters) Suitable torque screwdriver for previous operation "Snap On" QTSP135 or SPX 18 G.681 & T20 Torx bit.

Note:
Loose securing screws may cause squeaks and rattles, over tightened securing screws may strip the thread.

16. Secure paper adhesive label to back plate.

17. Place Instrument pack aside - careful not to damage the lens.

18. Reinstall Instrument pack. Refer to JTIS section 413-01, SRO 88.20.24 for XK vehicles, 501-12 for XJ vehicles.

19. Disconnect the wrist strap and place the anti static mat aside.

20. Reposition the luggage compartment floor carpet upwards for access and using a suitable permanent marking pen, mark VCATS label, in the spare wheel well, to indicate the service fix. (S484)

21. Reinstall the luggage compartment floor carpet in its original condition.

22. Reinstall instrument panel veneer panel.

23. Reinstall driver side dash liner

24. Reconnect battery. Refer to technical bulletin 414-01.

25. Reset customer preferences such as sport mode switch, cruise control, clock settings, etc.

26. Remove interior protection kit.

27. Perform a squeaks and rattle test on completion of the rework procedure.
