System Check and 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.
NOTE: The HDS can be used to:
  • Check the state of the immobilizer key registration and the IMOCD (S-NET) line by doing a SYSTEM CHECK.
  • Check the number of times the immobilizer control unit-receiver doesn't permit the engine to run by checking the STATUS LOG. Troubleshoot the line with the highest count first.
  1. Connect the HDS to the data link connector, then turn the ignition switch ON (II) and follow the prompts to the MAIN MENU.
    NOTE: If the HDS does not communicate with the vehicle, go to the DLC circuit troubleshooting (see DLC CIRCUIT TROUBLESHOOTING ).
  2. At the MAIN MENU, enter IMMOBILIZER, then select the IMMOBILIZER SETUP.
  3. Do the SYSTEM CHECK. If there is a system check number, do the troubleshooting for the item indicated.
  4. Check the status log using the HDS. Troubleshoot the line with the highest counts. If all the lines are "0" zero, the problem may not be caused by the immobilizer system, check for ignition or fuel problems.
    NOTE: Once repaired, clear the status log by removing the No. 7 (10 A) fuse in the under-dash fuse box or disconnecting the immobilizer control unit-receiver.
