General Check Before Troubleshooting

Before troubleshooting the immobilizer system, check the following general items and resolve any issues, if applicable:

The 12 volt battery is low; charge the battery fully, then troubleshoot the immobilizer system.
The ignition key is not a genuine Honda part; use a Honda-approved key blank, register the key, then troubleshoot the immobilizer system.
If a key ring or a key case is used; remove the key from it, and troubleshoot the immobilizer system with the key only.
An aftermarket electrical part is installed; remove it, then troubleshoot the immobilizer system.
