Keyless Access System Status Log

If you suspect there is an immobilizer system problem, check the status log in the HDS.

1. Connect the HDS to the data link connector (DLC) - Refer to: How to Troubleshoot the Body Electrical (2019 2020 2021) or How to Troubleshoot the Body Electrical (2022 2023) .

2. Turn the vehicle to the ON mode.

3. On the HDS screen, at SYSTEM SELECTION MENU, enter ONE-PUSH START, then select KEYLESS ACCESS CONTROL UNIT or BACKUP CONTROL UNIT.

NOTE: If the HDS does not communicate, check the body control module power, ground, K-line, and L-line connectors.

4. At KEYLESS ACCESS CONTROL UNIT, enter KEYLESS ACCESS SYSTEM INFORMATION, then select KEYLESS ACCESS STATUS LOG.

5. At BACKUP CONTROL UNIT, enter SYSTEM INFORMATION, 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.
