- For 2004-05 models, see «POWERTRAIN DTC SUMMARIES - ALL MODELS»(ref-171104) article.
DIAGNOSTIC STRATEGY
The complexity of the electronics involved with the automatic transmission/transaxle preclude the use of workshop general electrical test equipment. Therefore, reference should be made to the Jaguar approved diagnostic system for detailed instructions on testing the automatic transmission/transaxle.
Where a fault involving the automatic transmission/transaxle is indicated by the Jaguar approved diagnostic system, some basic diagnostic methods may be necessary to confirm that connections are good and that the wiring is not damaged, before installing new components.
- Verify the customer concern by operating the vehicle. Refer to the automatic transmission diagnostic drive cycle in the DTC summary section.
- Check the fluid levels and condition of the fluid.
- Check for non-factory fitted items.
- Check the «SELECTOR LEVER CABLE ADJUSTMENT»(ref-173250-S00574924162005031100000) .
- Visually inspect for obvious signs of mechanical, electrical or hydraulic damage.
