Section 32 (Engine Controls - System/Component Tests): Introduction

WARNING: This page is about a different car, the 1997 Suzuki X-90. However, it is still accessible from the selected car via links, so may be relevant.

Before testing separate components or systems, perform basic diagnostic procedures in BASIC TESTING article. Since many computer-controlled and monitored components set a Diagnostic Trouble Code (DTC) if they malfunction, also perform self-diagnostics in TESTS W/CODES article.

NOTE: Testing individual components does not isolate shorts or opens. Perform all voltage tests with a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance, unless stated otherwise in test procedure. Use ohmmeter to isolate wiring harness shorts or opens.
