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.
Panic Alarm Operation
When key switch is OFF (when ignition key is not inserted in key cylinder), BCM turns on and off horn intermittently with input of PANIC ALARM signal from keyfob.
BCM outputs to IPDM E/R for panic alarm signal (horn signal) as DATA LINE (CAN H line and CAN L line).
The alarm automatically turns off after 25 seconds or when BCM receives any signal from keyfob.
Panic alarm operation mode can be changed using "PANIC ALARM SET" mode in "WORK SUPPORT".
Refer to "WORK SUPPORT ".
