System Check and Status Log

NOTE: The HDS can be used to:

1. Connect the HDS to the DLC

, then turn the vehicle to the ON mode and follow the prompts to the SYSTEM SELECTION MENU.

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 STATUS LOG using the HDS - Refer to: Keyless Access System Status Log  or Keyless Access System Check 

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. C17 fuse or disconnecting the 12 volt battery.
