2008 Acura TSX AutomaticSECTION Status Log

If you suspect there is an immobilizer system problem, cheek the status log.

NOTE: Status log may not be available for all models. If you have an updated immobilizer control unit-receiver ('04 models) or a '05-08 models, 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.
