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) How to Connect the HDS
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 keyless access/TPMS control unit 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.
6. 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.
