Inspection And Verification

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

WARNING:

Cooling fans may continue to operate after the engine is turned off. They may also start to operate after the engine is turned off and continue operating for up to 10 minutes. Failure to follow this instruction may result in personal injury.
Always keep hands, tools, clothing and any equipment away from rotating belts and pulleys. Failure to follow this instruction may result in personal injury.

CAUTION:

If the engine is run without the accessory drive belt installed (to eliminate driven components), Diagnostic Trouble Code(s) (DTC(s))s may be set which must be cleared before the vehicle is returned to the owner. The engine should not be run for more than three minutes without the accessory drive belt installed. Failure to follow this instruction may result in damage to the vehicle.
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.

NOTE:

If a control module or a component is at fault and the vehicle remains under manufacturer warranty, refer to the Warranty Policy and Procedures service information, or determine if any prior approval program is in operation, prior to the installation of a new module/component.
When performing voltage or resistance tests, always use a digital multimeter accurate to three decimal places, and with an up-to-date calibration certificate. 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.
