Radio Always On

RADIO ALWAYS ON

DIAGNOSTIC AIDS
The radio is enabled/disabled by class 2 messages from the body control module (BCM). The BCM contains an audio delay power timer which allows the radio to operate for up to 10 minutes after the ignition is turned off. The radio is deactivated when one of the following occurs:
1. The driver door is open.
2. The 10 minutes timer has elapsed.
3. Loss of state of health message from the BCM.

If class 2 communication between the radio, BCM and data link connector is functioning properly, and the door ajar switches are working properly, replace the BCM.
