1. Switch the ignition ON.

2. Wait for approx. 1 min until the security light displays a DTC.
NOTE:
- When the ignition is switched ON with the following DTC detected, a DTC is displayed after the security light is flashed or illuminated for approx. 1 min.

- If a DTC in the tens is detected, the security light flashes for approx. 1 min.
- If a DTC in the twenties is detected, the security light illuminates for approx. 1 min.

- If the security light turns off after approx. 3 s, verify the DTC using the M-MDS because the immobilizer system is normal or there is a DTC which cannot be verified by the security light.
