Immobilizer System Symptom Troubleshooting Information
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 12 volt 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.
Symptom Troubleshooting Using the Security Indicator Lighting Pattern
The pattern of the security indicator can help troubleshoot the condition of the immobilizer system. Here are descriptions of the four possible patterns:
Normal operation:
When turning the vehicle to the ON mode and the immobilizer code is identified, the security indicator is OFF.
Immobilizer code is not identified:
When turning the vehicle to the ON mode when the immobilizer code has not been identified, the security indicator blink until the OFF (LOCK) mode is selected. Then security indicator will come on for 1 second. The state of the keyless registration and the S-NET line can be checked by doing a SYSTEM CHECK and STATUS LOG with the HDS.
Security indicator turns on:
If the security indicator turns on, do the gauge control module self-diagnostic function. If the indicator drive circuit is OK, do the SYSTEM CHECK and STATUS LOG with the HDS.
Symptom Troubleshooting Using Malfunctioning Circuit Functions
If a malfunction occurs in the immobilizer circuit, use the table to cross-reference the malfunction criteria to the line(s) that should be checked in the table:
System Check
NOTE: The HDS can be used to check the state of the immobilizer key registration and the S-NET line by doing a SYSTEM CHECK.
