Diagnosis and testing
Electronic Engine Controls Overview 2006MY sees the introduction of diesel to X350 and is accompanied by a diesel particulate filter (DPF) system to comply with strict stage four emissions requirements. Active engine mounts are also fitted and reduce transmitted vibration from the engine to the chassis when operating between 600 and 850rpm.
For more information on these systems, Exhaust System and Engine
The engine management system (EMS) on 2006MY diesel makes use of 7-digit diagnostic trouble codes (DTCs) rather than the familiar 5-digit.
Refer to the DTC index in this section for guidance on how to use these codes with the Jaguar approved diagnostic system or a scan tool. Inspection and Verification 1 . Verify the customer concern.
