Inspection And Verification
WARNING: This page is about a different car, the 2018 Land Rover Discovery Sport. 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.
The vehicle should not be driven if the fluid level is low as internal failure can result.
When the wheels are free of the ground (for example, when the vehicle is on a lift), do not drive the vehicle in any gear higher than 4th gear. Failure to comply with this instruction may cause DTCs to set or damage to the automatic transmission.

NOTE:
If a control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the Warranty Policy and Procedures manual, 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.
A road test should be performed by a suitably qualified and experienced technician in accordance with: Jaguar Land Rover - Service Experience Framework (SEF) - 4.4 Road Test Check Sheet. The customer should be present and ideally should drive the vehicle.

- If the cause is not visually evident, verify the symptom and refer to the Symptom Chart , alternatively check for Diagnostic Trouble Codes (DTCs) and refer to the DTC Index
- Check DDW 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
