Diagnosis & Repair

  1. Connect scan tool to DLC. Using scan tool, clear DTC information. Road test vehicle. If necessary, repeat road test. If vehicle does not start, crank engine so that DTC P0603 can set. If DTC P0603 sets, replace PCM. After repair is completed, go to next step. If DTC P0603 does not set, go to DIAGNOSTIC AIDS. Check for an intermittent problem. See the TESTS W/O CODES article.
  2. After repairs, using scan tool, clear DTC information. Road test vehicle within freeze frame conditions that set DTC. Check for DTCs. If no DTCs are stored, repair is complete. If any DTCs are set, go to appropriate DTC diagnostic test.
