Inspection and Verification
WARNING: Servicing must be carried out by personnel familiar with both vehicle system and the charging and testing
equipment. All operations must be carried out in a well ventilated area away from open flame and heat sources.
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.
NOTE: Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
