Symptom Troubleshooting by the Immobilizer Indicator Lighting Pattern
The pattern of the immobilizer indicator can help troubleshoot the condition of the immobilizer system. Following are descriptions of the four possible patterns:
Normal operation
If the immobilizer code is identified, the immobilizer indicator comes on for 2 seconds, then goes off after turning the ignition switch 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 comes on for 2 seconds, then blinks after turning the ignition switch to ON (II).
The immobilizer indicator blinks ten times, then goes off when the ignition switch is turned to LOCK (0).
Immobilizer indicator does not come on
If the immobilizer indicator does not come on after turning the ignition switch to ON (II), 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. Before troubleshooting the immobilizer system, check the following general points and solve any if applicable.
