Section 11 (Engine Controls - System & Component Testing): Introduction
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2000 Isuzu VehiCROSS, 2000 Isuzu Trooper, 2000 Isuzu Rodeo, 2000 Isuzu Hombre, and 2000 Isuzu Amigo. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
This article also applies to Honda Passport. For Passport coverage, refer to Rodeo, unless otherwise indicated.
NOTE:
For circuit identification, see appropriate wiring diagram in
WIRING DIAGRAMS article.
NOTE:
Testing individual components does not isolate shorts or opens. Perform all voltage tests using a Digital Volt-Ohmmeter (DVOM) with minimum 10-megohm input impedance, unless stated otherwise in test procedure. Use ohmmeter to isolate wiring harness shorts or opens. Testing procedures not covered in this article require a scan tool. See appropriate SELF-DIAGNOSTICS article.
Before testing separate components or systems, perform procedures in BASIC DIAGNOSTIC PROCEDURES article. Since many computer-controlled and monitored components set a diagnostic trouble code if they malfunction, also perform procedures in appropriate SELF-DIAGNOSTICS article.
