  4. If resistance is less than 5 ohms, repair short to ground in Light Green wire. Perform TEST VER-1. If resistance is more than 5 ohms, go to next step.
  5. Using an external ohmmeter, check resistance of Pink wire between data link connector and PCM connector terminal No. 25. If resistance is more than 5 ohms, repair open in Pink wire. Perform TEST VER-1. If resistance is less than 5 ohms, go to next step.
  6. Using an external ohmmeter, check resistance of Light Green wire between data link connector and PCM connector terminal No. 45. If resistance is more than 5 ohms, repair open in Light Green wire. Perform TEST VER-1. If resistance is less than 5 ohms, go to next step.
  7. Connect DRB to a functional data link connector on another vehicle. Turn ignition on. Using DRB, attempt to read trouble codes. If DRB does not display NO RESPONSE, replace PCM on initial vehicle. Perform TEST VER-1  .
  8. If DRB displays NO RESPONSE, substitute another DRB cartridge. Using DRB, attempt to read trouble codes. If DRB does not display NO RESPONSE, replace DRB cartridge.
