System Check and Status Log

NOTE: The HDS can be used to:

Check the state of the immobilizer key registration and the IMOCD 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.

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 ).
At the MAIN MENU, enter IMMOBILIZER, then select the IMMOBILIZER SET UP.
Do the SYSTEM CHECK. If there is a system check number, do the troubleshooting for the item indicated (see SYSTEM CHECK ).
Check the status log using the HDS. Troubleshoot the line with the highest counts (see STATUS LOG ). 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 (7.5 A) fuse in the under-dash fuse/relay box or disconnecting the battery.
