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.
Key-In-Ignition Warning
The radio activates the key-in-ignition audible warning as requested by the IPC. The IPC sends a class 2 message to the radio indicating the chime frequency of a medium rate and at a continuous duration. The key-in-ignition warning sounds when the following occurs:
- The ignition switch is OFF.
- The body control module (BCM) determines that the driver's door is open and the signal circuit is low. The IPC receives a class 2 message from the BCM indicating the door ajar status.
- The BCM determines that the key-in-ignition switch is open and the signal circuit is high. The IPC receives a class 2 message from the BCM indicating the key-in-ignition status.
