WARNING: This page is about a different car, the 2006 Acura MDX, 2005 Acura MDX, 2004 Acura MDX, and 2003 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.

NOTE: The status log may not be available for all models. If you have an updated immobilizer control unit-receiver ('03-04 models) or on '05-06 models, the status log should be available.
  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.
