Verification Procedure VER-1

  1. Inspect vehicle to ensure all engine components are connected. Reassemble and reconnect components as necessary. Inspect engine oil for fuel contamination. Change oil and filter if necessary. Attempt to start engine.
  2. If engine does not start, check if any TECHNICAL SERVICE BULLETINS (TSBs) apply to vehicle and return to TEST FC-1A, if necessary. If engine starts and Powertrain Control Module (PCM) was changed, repair is complete. If engine starts and PCM was not changed, connect DRB-II to data link connector and erase fault messages. Repair is complete.
