Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Indicator Lights: Security
Light Emitting Diode (LED) is controlled by Instrument Panel Cluster (IPC), using Class 2 data from Body Control Module (BCM). As a check, LED illuminates briefly when key is turned to run, until engine starts. If LED flashes, system has entered a tamper mode. If LED stays on while driving, system malfunction exists and vehicle will not be protected by security system. A system related DTC may be stored.
