Code B2244 GMC Description

The driver door switch signal circuits provide input to the Driver Door Module (DDM) when the memory 1 or memory 2 select switch is activated. These inputs allow the DDM to detect a memory function recall request. The DDM provides power and ground to the memory switches. When a memory select switch is activated, ground is supplied through the memory select switch to the signal circuit, which is pulled low. When the DDM detects low voltage on the signal circuit, it will activate the memory functions and also send a message on the serial data line to other modules responsible for memory recall functions. The DDM monitors the signal circuits to determine how long the ground has been applied. If the DDM detects that a ground is applied for greater than 20 seconds, a Diagnostic Trouble Code (DTC) is set.
