Note. Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review the General Troubleshooting Information (see GENERAL TROUBLESHOOTING INFORMATION ).

  1. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.
  2. Clear the DTC with the HDS.
  3. Check for Pending or Confirmed DTCs in the PGM-FI SYSTEM with the HDS. Is DTC P062F indicated in the PGM-FI SYSTEM? YES -Go to the DTC P062F troubleshooting in the PGM-FI SYSTEM (see «DTC P062F: PCM INTERNAL CONTROL MODULE KEEP ALIVE MEMORY (KAM) ERROR»(/acura/zdx/i-2009-2013/remont/testing-diagnostics/#pgm-fi-system__dtc-p062f-pcm-internal-control-module) ). NO -Go to step 4.
  4. Check for Pending or Confirmed DTCs in the A/T SYSTEM with the HDS. Is DTC P062F indicated in the A/T SYSTEM? YES -Go to step 5. NO -Intermittent failure, the system is OK at this time. If any other Pending or Confirmed DTCs were indicated, go to the indicated «DTC'S TROUBLESHOOTING»(/acura/zdx/i-2009-2013/remont/automatic-trans/#automatic-transmission) .
  5. Update the PCM if it does not have the latest software (see «PCM UPDATE»(/acura/zdx/i-2009-2013/remont/testing-diagnostics/#pgm-fi-system__pcm-update) ), or substitute a known-good PCM (see «SUBSTITUTING THE PCM»(/acura/zdx/i-2009-2013/remont/testing-diagnostics/#fuel-and-emissions-systems__substituting-the-pcm) ).
  6. Start the engine, and wait for at least 1 minute.
  7. Check for Pending or Confirmed DTCs in the A/T SYSTEM with the HDS. Is DTC P062F indicated in the A/T SYSTEM? YES -Check for poor connections or loose terminals at the PCM. If the PCM was updated, substitute a known-good PCM (see «SUBSTITUTING THE PCM»(/acura/zdx/i-2009-2013/remont/testing-diagnostics/#fuel-and-emissions-systems__substituting-the-pcm) ), then go to step 6 . If the PCM was substituted, go to step 2 . NO -Go to step 8.
  8. Monitor the OBD STATUS for P062F in the DTCs MENU with the HDS. Does the HDS indicate PASSED? YES -If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the original PCM (see «PCM REPLACEMENT»(/acura/zdx/i-2009-2013/remont/testing-diagnostics/#pgm-fi-system__pcm-replacement) ). If any other Pending or Confirmed DTCs were indicated in step 7 , go to the indicated «DTC'S TROUBLESHOOTING»(/acura/zdx/i-2009-2013/remont/automatic-trans/#automatic-transmission) . NO -If the HDS indicates FAILED, check for poor connections or loose terminals at the PCM. If the PCM was updated, substitute a known-good PCM (see «SUBSTITUTING THE PCM»(/acura/zdx/i-2009-2013/remont/testing-diagnostics/#fuel-and-emissions-systems__substituting-the-pcm) ), then go to step 6 . If the PCM was substituted, go to step 2 . If the HDS indicates NOT COMPLETED, go to step 6 .
