SERVICE AWD Indicator Always On

Circuit Description
The SERVICE AWD indicator is located in the instrument panel cluster (IPC). It receives ignition voltage through the IPC 10 amp gage fuse through the ignition 1 voltage circuit. The ignition 1 voltage circuit also supplies all of the gages with ignition voltage. The transfer case shift control module controls the SERVICE AWD indicator by sending the IPC a Class 2 message. This indicator may be controlled with the scan tool using the IPC output controls.
