Keyless Access System Status Log

2020 Honda HR-V LX, FWDSECTION Keyless Access System Status Log

If you suspect there is an ONE-PUSH START system problem, check the status log in the HDS.

1. Connect the HDS to the data link connector (DLC)

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 control unit power, ground, K LINE and L-LINE connectors.

4. At KEYLESS ACCESS CONTROL UNIT, enter KEYLESS ACCESS SYSTEM INFORMATION, then select 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 ONE-PUSH START system is OK. Continue with normal symptom troubleshooting.
