Troubleshooter

is a database of experience-based information that has been compiled by top-notch technicians, and contains basic information on many common diagnostic trouble codes (DTCs).

Selecting Troubleshooter from the Vehicle Systems Test/Function menu opens a submenu of options (options may vary).

●

Code Tips—provides detailed information on setting conditions, testing, and interpreting test results for specific codes.

●

Symptom Tips—provides diagnostic tests and procedures based on vehicle operation.

●

Time Savers—provides supplemental information, such as firing order and #1 cylinder location, that may be needed to make a diagnosis.

●

Tests and Procedures—explains how to perform certain tests on the specific test vehicle. Some tips provide specifications and installation information as well.

Troubleshooter information is organized into a series of diagnostic tips that are designed to quickly lead you to the root cause of a particular problem. The tips are vehicle‑specific, which means only tips that relate to the identified vehicle are presented.
