|What Does the B2222 Code Mean?

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