Status Log
WARNING: This page is about a different car, the 2011 Acura TL, 2010 Acura TL, and 2009 Acura TL. 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 in the HDS
- Connect the HDS to the data link connector
- Turn the ignition switch to ON (II)
- On the HDS screen, at MAIN MENU, enter IMMOBI, then select IMMOBILIZER SETUP, select System Check, Number of Keys, and Status Log, then select STATUS LOG
- 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
