Diagnostic Notes - Read First

Vehicle Preparation for Testing
Make sure the vehicle being tested has a fully charged battery. If it does not, false diagnostic codes or error messages may occur.

Servicing Sub-Assemblies
Some components of the body system are intended to be serviced in assembly only. Attempting to remove or repair certain system sub-components may result in personal injury and/or improper system operation. Only those components with approved repair and installation procedures should be serviced.
