Section 13 (Engine Controls - Self-Diagnostics): Introduction
WARNING: This page is about a different car, the 2002 Suzuki Grand Vitara. However, it is still accessible from the selected car via links, so may be relevant.
Most engine control problems result from mechanical failures, poor electrical connections, or damaged vacuum hoses. Before condemning the computer system, perform checks and inspections covered in BASIC DIAGNOSTIC PROCEDURES article. Failure to do so may result in lost diagnostic time.
If no Diagnostic Trouble Codes (DTCs) are present, and driveability problems exist, proceed to SYMPTOMS in TROUBLE SHOOTING - NO CODES article for diagnosis by symptom (i.e., rough idle, no start, etc.).
