Diagnostic Procedures

WARNING: This page is about a different car, the 2000 Pontiac Firebird, 2000 Chevrolet Corvette, and 2000 Chevrolet Camaro. However, it is still accessible from the selected car via links, so may be relevant.
  1. Perform On-Board Diagnostic (OBD) system check. See ON-BOARD DIAGNOSTIC (OBD) SYSTEM CHECK  under SELF-DIAGNOSTIC SYSTEM. After performing OBD system check, go to next step.
  2. Start and operate engine at idle. Using scan tool, select MISFIRE DATA LIST and monitor IC NO. 3 status. If scan tool indicates DTC P0353, go to step  4. If scan tool does not indicate this DTC, go to next step.
  3. Turn ignition on, with engine off. Using scan tool, review FREEZE FRAME and/or FAILURE RECORDS data and note parameters. Turn ignition off for about 15 seconds. Start engine and operate vehicle within conditions required for this diagnostic to run, and as close to conditions recorded in FREEZE FRAME/FAILURE RECORDS as possible. Select DTC function, then enter this DTC. If scan tool indicates that this test failed this ignition, go to next step. If scan tool does not indicate that this test failed this ignition, see DIAGNOSTIC AIDS .
  4. Turn ignition off. Disconnect ignition coil No. 3 connector. Using a DVOM in AC Hertz (Hz) scale, check frequency of IC signal circuit. Start and operate engine at idle. If frequency is 3-20 Hz, go to step  8. If frequency is not as specified, go to next step.
  5. Using DVOM, check voltage on IC No. 3 signal circuit. If voltage reading is greater than 1.0 volt, go to step  14. If voltage reading is not greater than 1.0 volt, go to next step.
  6. Turn ignition off. Disconnect PCM harness connector. Using DVOM, check continuity of IC signal circuit from ignition coil No. 3 connector to PCM connector. If continuity exists, go to next step. If continuity does not exist, go to step  15.
  7. Using DVOM, check resistance of IC signal between ground and ignition coil No. 3 connector. If resistance is infinite, go to step  16. If resistance is not infinite, go to step  15.
  8. Using a test light connected to battery ground, probe IC module ignition feed circuit. If test light illuminates, go to next step. If test light does not illuminate, go to step  10.
  9. Connect test light to battery voltage and probe IC module ground circuit. If test light illuminates, go to step  12. If test light does not illuminate, go to step  11.
  10. Repair ignition feed circuit for open between IC module harness connector and splice. After repairs, go to step  18.
  11. Repair ground circuit for open between IC module harness connector and splice. After repairs, go to step  18.
  12. Check for poor connection at IC module. Repair as necessary. After repairs, go to step  18. If connection is okay, go to next step.
  13. Replace IC module. After replacing module, go to step  18.
  14. Repair IC signal circuit for short to voltage. After repairs, go to step  18.
  15. Repair IC signal circuit for open or short to ground. After repairs, go to step  18.
  16. Check for poor connections/terminal tension at PCM connector. Repair as necessary. After repairs, go to step  18. If connection or terminal tension is okay, go to next step.
  17. Replace PCM. Program replacement PCM using required equipment. After replacing PCM, go to next step.
  18. Using scan tool, select DTC, CLEAR INFO function. Start and warm engine to normal operating temperature. Select DTC, SPECIFIC, then enter this DTC. Operate vehicle within conditions for setting this DTC. If scan tool indicates that this test ran and passed, go to next step. If scan tool does not indicate that this test ran and passed, repeat step  2.
  19. Using scan tool, select CAPTURE INFO, REVIEW INFO function. If any undiagnosed DTCs are displayed, go to applicable DTC test.
