Component Tests and General Diagnostics
Air Leaks1. CAUTION: Any spray used must have a corrosion inhibitor, and must not cause damage to paintwork, plastics, metals or plastic pipes.
NOTE: The recommended leak detection spray is GOTEC LDS, Jaguar part number C2C 22398.
The recommended leak detection spray should be used to identify any suspected leaks. This procedure should also be used where any of the air suspension components have been disturbed.
2. Clean around the area of the suspected air leak.
3. Using the recommended leak detection spray, spray around all of the air suspension components, working systematically until the source of the air leak has been found.
4. NOTE: If a new air suspension component is to be fitted, and no air leak has been detected at the pipe connectors, remove and discard the new air pipe connections supplied with the component.
If any of the air suspension components are found to be leaking e.g. air spring, compressor, reservoir or the solenoid valve block repair is effected by replacement only. if an air leak from the pipe connector has also been identified, a new air pipe connector, supplied with the air suspension component, must be installed.
5. NOTE: Only Jaguar approved connectors have been tested to the correct pressure and temperature specifications.
NOTE: Air pipes must only be cut using either Hose cutter 204-494, available from SPX LTD or Hose cutter YA1000A, available from Snap-On Tools.
NOTE: If the color coded markings adjacent to the pipe connections are removed when cutting air pipes, the cut end of the air pipe must be clearly marked with a suitable colored tape or paint mark.
If the source of the air leak is found to be a pipe connection cut 5 mm (0.2 inch) off the end of the air pipe and fit a new connector.
6. NOTE: Air pipes must only be cut using either Hose cutter 204-494, available from SPX LTD or Hose cutter YA1000A, available from Snap-On Tools.
NOTE: Only Jaguar approved air pipes have been tested to the correct pressure and temperature specifications.
If the source of the air leak is found to be in a section of pipe cut out the damaged section of air pipe and replace with new air pipe and air pipe connectors as required.
7. NOTE: If the repair has been unsuccessful repeat the above steps until the air leak is rectified.
Using the Jaguar approved diagnostic system ensure that the system is fully pressurized.
8. Using the recommended leak detection spray, spray around all of the air suspension components, working systematically to make sure that the source of the air leak has been found.
Ride Height Adjustments
Ride height gauge. 204-484
1. NOTE: Fit special tool 204-484 as illustrated.
NOTE: Make sure that the ride height gauge is vertical as shown.
Using the Jaguar approved diagnostic system carry out the ride height adjustments.
