System Check and Status Log

NOTE:  The HDS can be used to:

• Check the state of the keyless remote registration and the S-NET line by doing the Keyless Access System Check .
• Check the number of times the keyless access/TPMS control unit or the backup control unit did not permit the engine to start by checking the Keyless Access System Status Log .

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 - Refer to:

DLC Circuit Troubleshooting (With CAN Gateway) (2019 2020 2021) or

DLC Circuit Troubleshooting (Without CAN Gateway) (2019 2020 2021) .

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 Keyless Access System Check 2.

4. At BACKUP CONTROL UNIT, enter SYSTEM INFORMATION, then select Keyless Access 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 using the HDS.

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 fuse. - Go to: Fuse to Components Index (Without Auto Idle Stop System) (2019 2020 2021) disconnecting the 12 volt battery.
