Begin the system diagnosis with DIAGNOSTIC SYSTEM CHECK - VEHICLE . The Diagnostic System Check - Vehicle will provide a complete strategy to locate and repair a mechanical or electrical vehicle fault. Not following this strategy may cause additional diagnostic time and/or misdiagnosis.

The Diagnostic System Check - Vehicle will provide the following strategy:

• When to verify the customer concern and identify related bulletins, recalls and preliminary information
• When to identify a control module that is not communicating, a control module that has set a DTC, and the DTC diagnostic priority
• When to address power mode concerns
• When to verify the engine cranks and runs
• When to diagnose symptom related concerns
