Immobilizer System

CAUTION: When the engine does not start or stalls and the DTCs are not indicated, go to symptom troubleshooting. (See Computers/Testing.)

NOTE:
- When the immobilizer system is defective, the engine starts once and soon stalls after the starter is turned for the first three times. The engine cannot be started after the third time.
- If engine condition is normal but light stays on, inspect for short circuit between security light and immobilizer unit connector terminal M. Repair or replace the wiring harness if necessary.

1. Turn the ignition switch to START position for 2 seconds, then back to ON position.
2. Wait for 2 minutes.
3. Verify the security light condition and read the DTC if indicated.
4. Verify the DTC with NGS set or equivalent.
5. If the DTC is indicated, go to troubleshooting referring to the DTC table.
