Status Log

WARNING: This page is about a different car, the 2009 Acura MDX, 2008 Acura MDX, and 2007 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.

If you suspect there is a immobilizer system problem, check the status log.

  1. Connect the HDS to the data link connector.
  2. Turn the ignition switch ON (II).
  3. On the HDS screen, select Honda systems, select immobilizer set-up, select immobilizer information, then select status log.
  4. Check the Status log count. Troubleshoot the status with the highest count first. If no counts are listed, the immobilizer system is OK. Continue with normal symptom troubleshooting.
