Before troubleshooting the immobilizer system, check the following general items to minimize troubleshooting time:
- If the battery is low; fully charge the battery, then troubleshoot the immobilizer system.
- The ignition key is not a genuine Acura part; use the Acura-approved key blank, register the key, then troubleshoot the immobilizer system.
- Check to see if a key ring, or a key case is used; remove the immobilizer key from it, and troubleshoot the immobilizer system with the immobilizer key only.
- Check to see if an aftermarket electrical part is attached; remove it, then troubleshoot the immobilizer system.
