Telephone Interference - Install Generator
Suppression Module

Issue:
Some 1998 MY-ON V8 XJ Series vehicles may experience interference noise during a telephone call, after the driver has increased the volume to compensate for exterior noise. This condition can be resolved by installing a generator suppression module.

Action:
After verifying a customer complaint of the above condition on a 1998 MY-ON V8 XJ Series vehicle, proceed as follows:

INSTALLING GENERATOR SUPPRESSION MODULE

1. Remove the battery cover and disconnect the battery but leave the ignition key in the lock.

2. Raise the vehicle on a hoist which will allow the front wheels to hang free.

3. Turn the steering to full lock to allow access to the area in front of the suspension at the right side wheel well.





4. Install the bracket on the module, as shown in Illustration 1, with the three screws and nuts.

5. Connect the generator link harness plug to the module fly lead plug.

6. Install the support clip to the bracket and then install the fly-lead plug into the clip, as shown in Illustration 1.

7. Move the wheel well liner aside to allow access to the under side of the chassis rail.

8. Thread the remaining two screws into the tapped holes in the bottom of the chassis rail.

9. Install the suppression module assembly on the chassis rail by placing the "keyhole" slots over the bolt heads, sliding the assembly into position and then tightening the screws.

Note:
The position of the assembly must be as illustrated, (as viewed under the right side wheel well), with the module fly lead towards the front of the vehicle and the module angled downward at the rear.





10. Move the boot aside to expose the generator main terminal (upper arrow, illustration 2).

11. Remove the retaining nut and the main lead from the terminal.

12. Loop the link harness as shown in Illustration 1 to reach the generator.

13. Connect the brown lead and the main lead to the terminal post, secure them with the nut and then reinstall the boot.

14. Install the eyelet of the black lead on the lowest rear ground stud on the generator (lower arrow, Illustration 2) and then install and tighten the 5 mm. nut to secure it.

Note:
Do not over tighten the ground stud nut, the stud is fragile.

15. Use one of the tie straps to hold the loop in the link harness, as shown in Illustration 1. Before tightening the tie straps, make sure that the loop will not contact any moving part.





16. Use the second strap to secure the harness to the power steering return pipe, at the position indicated in Illustration 3.

17. Trim the excess from the tie straps.

18. Replace the wheel well liner in its original position, center the steering and then lower the vehicle.

19. Reconnect the battery, replace the battery cover and reset the clock.
