The cost to diagnose the B2242 GMC code is 1.0 hour of labor. The diagnosis time and labor rates at auto repair shops vary depending on the location, make and model of the vehicle, and even the engine type. Most auto repair shops charge between $75 and $150 per hour.
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.
