Section 43 (Engine Controls - System & Component Testing): Introduction
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 1999 Isuzu Oasis, 1998 Isuzu Oasis, 1998 Honda Prelude, 1998 Honda Odyssey, and 1998 Honda Civic. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
On Accord and Prelude models, when substituting a known-good PCM, immobilizer code must be rewritten to replacement PCM using Honda PGM tester, or engine will not start.
NOTE:
For testing and diagnosis of Variable Valve Timing (VTEC) system, see DTC P1253 or DTC P1259 in TESTS W/CODES - INTRODUCTION
article.
Before testing separate components or systems, perform procedures in BASIC TESTING article. Since many computer-controlled and monitored components set Diagnostic Trouble Code (DTC) if they malfunction, also perform procedures in TESTS W/CODES - INTRODUCTION article.
NOTE:
Before disconnecting battery, obtain anti-theft code for radio. After battery is reconnected, CODE will appear on radio display. Enter 5-digit anti-theft code using select buttons and radio will begin working. If code is entered wrong 3 times, leave radio on at least one hour and enter code correctly. Any time radio power is lost, pre-selected radio stations will have to be set. For more information, see owners manual.
NOTE:
Perform all voltage tests using a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance, unless stated otherwise in test procedure. Testing individual components does not isolate shorts or opens. Use ohmmeter to isolate wiring harness shorts or opens.
