Note. For connector terminal ID, see CONNECTOR IDENTIFICATION . For wiring diagram, see WIRING DIAGRAMS article.

  1. Using scan tool, read Diagnostic Trouble Codes (DTCs). If scan tool display GLOBAL GOOD TRIP is equal to zero, go to step 5 . If scan tool display GLOBAL GOOD TRIP is not equal to zero, go to next step.
  2. Condition to set trouble code is not present at this time. Inspect all related wiring and connectors and repair as necessary. If no problems were found with wiring and connectors, go to next step. If related wiring and connectors were repaired, perform «TEST VER-5A: ROAD TEST FOR OBD-II TROUBLE CODES»(ref-576-S06971814902000030800000) .
  3. Start engine. With engine idling, wiggle wiring harness from ignition coils to PCM. If wiggling caused engine to misfire or stall, or GLOBAL GOOD TRIP changed to zero, repair wiring harness as necessary where wiggling caused problem to appear. Perform «TEST VER-5A: ROAD TEST FOR OBD-II TROUBLE CODES»(ref-576-S06971814902000030800000) . If wiggling did not cause misfire or stall, or GLOBAL GOOD TRIP did not change to zero, go to next step.
  4. Using scan tool, read FREEZE FRAME data. Ensure hex code matches DTC on scan tool. Hex code should be 2A. Utilize FREEZE FRAME data to help in diagnostics. See «INACTIVE TROUBLE CODE CONDITION»(ref-576-S27765318282000030800000) under SELF-DIAGNOSTICS. Test is complete. Perform «TEST VER-5A: ROAD TEST FOR OBD-II TROUBLE CODES»(ref-576-S06971814902000030800000) .
  5. Turn ignition off. Disconnect 2-pin ignition coil No. 2 connector. Inspect ignition coil connector for damaged, pushed out or miswired terminals. Repair ignition coil connector as necessary. Perform «TEST VER-5A: ROAD TEST FOR OBD-II TROUBLE CODES»(ref-576-S06971814902000030800000) . If ignition coil connector is okay, go to next step.
  6. Reconnect ignition coil connector. Start engine. Using a 12-volt test light and Miller Tool (6801), backprobe ignition coil No. 2 connector fused ASD relay output circuit. See «IGNITION COIL NO. 2 CONNECTOR WIRE IDENTIFICATION»(ref-576-S10377223142000030800000) table. If test light illuminates brightly, go to next step. If test light does not illuminate brightly, repair fused ASD relay output circuit. Perform «TEST VER-5A: ROAD TEST FOR OBD-II TROUBLE CODES»(ref-576-S06971814902000030800000) .
  7. With engine still running, backprobe ignition coil No. 2 connector coil driver circuit. See «IGNITION COIL NO. 2 CONNECTOR WIRE IDENTIFICATION»(ref-576-S10377223142000030800000) table. If test light is not blinking, go to next step. If test light is blinking, replace ignition coil No. 2. Perform «TEST VER-5A: ROAD TEST FOR OBD-II TROUBLE CODES»(ref-576-S06971814902000030800000) .
  8. If test light is illuminated steadily and brightly, go to step 10 . If test light is not illuminated steadily and brightly, go to next step.
  9. Turn ignition off. Disconnect Powertrain Control Module (PCM) connector. Using an ohmmeter, check resistance of ignition coil No. 2 driver circuit between ignition coil connector (harness side) and PCM connector terminal No. 3. See «IGNITION COIL NO. 2 CONNECTOR WIRE IDENTIFICATION»(ref-576-S10377223142000030800000) table and «PCM CONNECTOR WIRE IDENTIFICATION»(ref-576-S01836285332000030800000) table. If resistance is 5 ohms or more, repair ignition coil No. 2 driver circuit for an open or high resistance. Perform «TEST VER-5A: ROAD TEST FOR OBD-II TROUBLE CODES»(ref-576-S06971814902000030800000) . If resistance is less than 5 ohms, replace PCM. Perform «TEST VER-5A: ROAD TEST FOR OBD-II TROUBLE CODES»(ref-576-S06971814902000030800000) .
  10. Turn ignition off. Disconnect Powertrain Control Module (PCM) connector. Using test light still connected to B+, touch test light to PCM connector terminal No. 3. See «PCM CONNECTOR WIRE IDENTIFICATION»(ref-576-S01836285332000030800000) . If test light is on, go to next step. If test light is not on, check ignition coil driver circuit for a short to ground. If ignition coil driver circuit was repaired, perform «TEST VER-5A: ROAD TEST FOR OBD-II TROUBLE CODES»(ref-576-S06971814902000030800000) . If ignition coil driver circuit was okay, replace faulty PCM. Perform «TEST VER-5A: ROAD TEST FOR OBD-II TROUBLE CODES»(ref-576-S06971814902000030800000) .
  11. Turn ignition off. Disconnect ignition coil No. 2 connector. Using test light still connected to B+, touch test light to PCM connector terminal No. 3. See «PCM CONNECTOR WIRE IDENTIFICATION»(ref-576-S01836285332000030800000) . If test light is on, repair short to ground on ignition coil No. 2 driver circuit. Perform «TEST VER-5A: ROAD TEST FOR OBD-II TROUBLE CODES»(ref-576-S06971814902000030800000) . If test light is not on, replace ignition coil No. 2. Perform «TEST VER-5A: ROAD TEST FOR OBD-II TROUBLE CODES»(ref-576-S06971814902000030800000) .
