System Check and Status Log

NOTE:  The HDS can be used to:

1. Connect the HDS to the data link connector (DLC), then turn the vehicle to the ON mode and follow the prompts to the SYSTEM SELECTION MENU.

NOTE:  If the HDS does not communicate with the vehicle, go to the DLC Circuit Troubleshooting (2016 2017 2018) .

2. At SYSTEM SELECTION MENU, enter ONE-PUSH START, then select KEYLESS ACCESS CONTROL UNIT or BACKUP CONTROL UNIT.

3. At KEYLESS ACCESS CONTROL UNIT, enter KEYLESS ACCESS SYSTEM INFORMATION, then select SYSTEM CHECK 1 or SYSTEM CHECK 2.

4. At BACKUP CONTROL UNIT, enter SYSTEM INFORMATION, then select SYSTEM CHECK.

5. Do the SYSTEM CHECK. If there is a system check number, do the troubleshooting for the item indicated.

6. Check the Keyless Access System Status Log

Troubleshoot the line with the highest counts first. If all the lines are 0 (zero), the problem may not be caused by the immobilizer system or keyless access system, check for ignition or fuel problems.

NOTE:  Once repaired, clear the status log by removing the No. A26 (10 A) fuse in the under-hood fuse/relay box or disconnecting the 12 volt battery.
