What Does the B2226 Cadillac Code Mean?

The driver door switch signal circuits provide inputs to the Driver Door Module (DDM) when the mirror switch is activated. These inputs allow the DDM to detect a mirror direction request. The DDM provides both power and ground to the mirror switches. When a mirror switch is activated to the right, left, up or down position, ground is supplied through the mirror switch to the signal circuit, which is pulled low. When the DDM detects low voltage on the signal circuit, it will command the mirror to rotate in the direction selected. The DDM controls passenger mirror functions by sending mirror control messages to the Passenger Door Module (PDM) on the serial data line and the PDM then commands the passenger mirror. The DDM monitors both the driver and passenger mirror switch signal circuits to determine how long a 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.
