Code B2239 Chevrolet Description

The driver or passenger door switch signal circuits provide inputs to the Driver Door Module (DDM) or Passenger Door Module (PDM) when a door lock switch is activated to the LOCK or UNLOCK position. These inputs allow the door module to detect a door LOCK or UNLOCK request. The door modules provide power and ground to the door lock switches. When a door lock switch is activated to the LOCK or UNLOCK position, ground is supplied through the door lock switch to the signal circuit, which is pulled low. When the door module detects low voltage on the signal circuit, it will command the door latches to LOCK or UNLOCK. If the driver door switch is activated, the DDM will LOCK or UNLOCK the driver door latch and also send a message on the serial data line to the PDM to LOCK or UNLOCK the passenger door latch. If the passenger door switch is activated, the PDM will LOCK or UNLOCK the passenger door latch and also send a message on the serial data line to the DDM to LOCK or UNLOCK the driver door latch. The door modules monitor the signal circuits to determine how long the ground has been applied. If the door module detects that a ground is applied for greater than 20 seconds, a Diagnostic Trouble Code (DTC) is set.
