Diagnosis and Testing Published: 11-May-2011

The complexity of the electronics involved with the JaguarNet system, of which the GPS antenna and navigation display are
parts, and the multiplexed communication network which are connected to it preclude the use of workshop general electrical
test equipment. Therefore, reference should be made to the approved Jaguar diagnostic system for detailed instructions on
testing the VEMS unit.
The approved Jaguar diagnostic system tests and analyses all functions of the VEMS and the various systems affected by it.

Where a fault is indicated, some basic diagnostic methods may be necessary to confirm that connections are good and that
wiring is not damaged before installing a new component.

Diagnosis and Testing

Inspection and Verification Published: 15-Jul-2014

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.
NOTES:


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 programme 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.
1. Verify the customer concern.

2. Visually inspect for obvious signs of damage, water ingress and system integrity.

3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to
the next step.
4. If the cause is not visually evident, check for Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.
