BEFORE YOU BEGIN
•
Fix any known mechanical problems before performing
any test.
Complete a thorough vehicle inspection before starting any
diagnostic procedure. Loose or damaged hoses, wiring, or
electrical connectors are often responsible for poor engine
performance, and in some cases these items may cause a
“false” fault code. Check the following areas:
•
All fluid levels
•
Belts
•
Vacuum Hoses
•
Wiring and Connectors
Please read your vehicle’s service manual and perform all
required preliminary checks BEFORE retrieving fault codes.
