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
Only serviceable items can be renewed or adjusted. Failure to follow this instruction may result in the warranty of the component being rejected

NOTE: Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests

Verify the customer concern by carrying out a road test of the vehicle

Visually inspect for obvious signs of mechanical damage and system integrity
