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.
NOTE: For diagnostic purposes the cylinders are divided into two banks: Bank 1 - Cylinder numbers 1, 2 and 3. Bank 2 - Cylinders 4, 5 and 6.
  1. Verify the customer concern.
  2. Visually inspect for obvious mechanical or electrical faults.
