Immobilizer System Symptom Troubleshooting Information

Symptom Troubleshooting Using the Immobilizer Indicator Lighting Pattern
The pattern of the immobilizer indicator can help troubleshoot the condition of the immobilizer system. Here are descriptions of the four possible patterns:
Normal operation
If the immobilizer code is identified, the immobilizer indicator quickly flashes once when the ignition switch is turned to ON (II).
The immobilizer indicator does not come on when the ignition switch is turned to LOCK (0).
Immobilizer code is not identified
If the immobilizer code is not identified, the immobilizer indicator will quickly flash once, then will blink until the ignition switch is turned to LOCK (0). When the ignition switch is turned to LOCK (0), the indicator will blink ten times, then go off.
The state of the immobilizer key registration and the IMOCD line can be checked by doing a SYSTEM CHECK with the HDS.
Immobilizer indicator does not come on
If the immobilizer indicator does not come on after turning the ignition switch to ON (II), there is an open or short in the F-CAN lines between the ECM/PCM and the gauge control module. Watch the malfunction indicator lamp (MIL). If the MIL stays on, go to the PGM-FI system troubleshooting.
Immobilizer indicator does not go off
If the immobilizer indicator does not go off after turning the ignition switch to ON (II), do the gauge control module self-diagnostic function. If the indicator drive circuit is OK, do the SYSTEM CHECK with the HDS.
