Inspection and verification
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-todate
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.
- Verify the customer concern
- Visually inspect for obvious signs of damage and system integrity
