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 checked and/or the donor vehicle
NOTE:
Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests
- Verify the customer concern
- Visually inspect for obvious signs of mechanical or electrical damage
