Diagnostic Procedures

WARNING: This page is about a different car, the 2000 Isuzu Rodeo and 2000 Isuzu Amigo. However, it is still accessible from the selected car via links, so may be relevant.
  1. Perform On-Board Diagnostic II (OBD-II) system check. See SELF-DIAGNOSTICS - INTRODUCTION article. Go to next step.
  2. Attempt to start engine. If engine starts, go to next step. If engine does not start, see ENGINE CRANKS BUT WILL NOT RUN under NO START DIAGNOSIS in BASIC DIAGNOSTIC PROCEDURES article.
  3. Using scan tool, clear DTCs. Run engine at idle for one minute and check scan tool. If DTC P0201-P0204 has reset, go to step  5. If DTC P0201-P0204 has not set, go to next step.
  4. Turn engine off. Turn ignition on. Using scan tool, read FREEZE FRAME data and note parameters. Operate vehicle within FREEZE FRAME conditions. If DTC P0201-P0204 has reset, go to next step. If no DTC is set, go to DIAGNOSTIC AIDS .
  5. Turn ignition off. Connect an Injector Test Light (J39021-45) to injector harness connector for pertinent cylinder. Disable secondary ignition system to prevent engine from starting, and crank engine. If test light flashes, perform fuel injector coil test. See FUEL SYSTEM in SYSTEM & COMPONENT TESTING article. If test light does not flash, go to next step.
  6. If injector test light was on steadily in previous step, go to next step. If test light was not on steadily in previous step, go to step  10.
  7. Disconnect PCM connector from affected injectors. Using test light connected to battery positive, probe affected injectors driver circuit at harness connector. If test light illuminates, go to next step. If test light does not illuminate, go to step  9.
  8. Repair short to ground in injector driver circuit. Perform On-Board Diagnostic II (OBD-II) system check. See SELF-DIAGNOSTICS - INTRODUCTION article.
  9. Replace and reprogram PCM using required equipment. See PROGRAMMING . Perform On-Board Diagnostic II (OBD-II) system check. See SELF-DIAGNOSTICS - INTRODUCTION article.
  10. Disconnect injector test connector. Turn ignition on. Connect test light to chassis ground and probe each terminal of injector harness connector (PCM side). If test light illuminates on Ignition (+) terminal only, go to step  12. If test light illuminates on other terminals including Ignition (+) terminal, go to next step.
  11. Repair short to voltage in injector driver circuit. Retest system.
  12. With test light still connected to ground, probe injector driver circuit (harness side). If test light illuminates on any terminal, go to step  11. If test light does not illuminate, go to next step.
  13. Turn ignition off. Using an ohmmeter, check for an open between ignition terminal of injector test connector and each of the other terminals of injector test connector. If all terminals have continuity, go to step  15. If any terminals were open, go to next step.
  14. Repair open in injector drive circuit or injector. Retest system.
  15. Check for an open in pertinent injector control circuit between injector test connector and PCM connector. If circuit is open, repair as necessary. Retest system. If circuit is okay, replace and reprogram PCM using required equipment. See PROGRAMMING . Retest system.
