Test VER-5A - Road Test For OBD-II DTCS

  1. Inspect vehicle to ensure all engine components are connected. Reassemble and reconnect components as necessary. If any DTCs have not been diagnosed, go to DTC TEST  and finish diagnosing remaining DTCs as necessary. If all DTCs have been diagnosed, go to next step.
  2. Connect scan tool to data link connector. Ensure fuel tank is at least 1/4 full. Ensure A/C is off and go to next step.
    NOTE: Proper way to ensure DTC has been repaired, is to allow Powertrain Control Module (PCM) to run scan tool monitors. Observe monitor operation on scan tool display. All specified enabling conditions for specified DTC must be met before PCM will operate monitors.
  3. Using scan tool, observe pre-test enabling conditions until all conditions have been met. Once all enabling conditions are met, observe appropriate DTC monitor on scan tool display.
  4. If repaired DTC has reset or was observed in monitor while on road test, repair is not complete. Check for related Technical Service Bulletins (TSBs) and return to DTC TEST  if necessary. If another DTC exists, return to DTC TEST and follow path specified by other DTC. If no other DTCs exist, repair is complete.
