Inspection And Verification

WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION:

Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle
Only serviceable items can be renewed or adjusted. Failure to follow this instruction may result in the warranty of the component being rejected

NOTE:

If a control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the Warranty Policy and Procedures information, or determine if any prior approval programme is in operation, prior to the installation of a new module/component
When performing voltage or resistance tests, always use a digital multimeter that has the resolution ability to view 3 decimal places. For example, on the 2 volts range can measure 1mV or 2 K Ohm range can measure 1 Ohm. When testing resistance always take the resistance of the digital multimeter leads into account
Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests

Verify the customer concern by carrying out a road test of the vehicle if safe to do so

Visually inspect for obvious signs of mechanical damage and system integrity

VISUAL INSPECTION

If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step
If the concern is not visually evident, verify the symptom and refer to the symptom chart
Check the Jaguar Land Rover (JLR) claims submission system for open campaigns. Refer to the corresponding bulletins and SSMs which may be valid for the specific customer complaint and carry out the recommendations as required
