DTC P2610: ECM/PCM Ignition Off Internal Timer Malfunction

  1. Turn the ignition switch ON (II).
  2. Clear the DTC with the HDS (see HDS CLEAR COMMAND ).
  3. Check for Temporary DTCs or DTCs with the HDS.

    Is P2610 indicated? 

    1. YES -  Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM (see ECM/PCM UPDATING AND SUBSTITUTION FOR TESTING ), then recheck. If the symptom/indication goes away with a known-good ECM/PCM, replace the original ECM/PCM (see ECM/PCM REPLACEMENT  ).
    2. NO -  Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at the ECM/PCM.
