About B2196

B2196 is a generic (obd-ii standard) body diagnostic trouble code. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B2196 is stored, the module has detected a short-circuit (voltage pulled to ground or to supply) in the monitored circuit.

Scanning & clearing: Body (B) codes are often stored in the body control module, airbag module, or climate module. A basic OBD-II tool usually will not read body codes — an enhanced or OEM-level scan tool is typically required.

Because B2196 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The Body Control Module (BCM) drives the front passenger window motor through an internal H bridge that supplies switched power and ground to either the up or down direction, with current sensing on each leg for protection. DTC B2196 sets when the BCM detects that one of the front passenger window motor power outputs (up or down) has shorted to ground, indicated by excessive current draw or a clamped output voltage when the motor is commanded. Because the H bridge needs both polarities of the supply available to operate the motor, a shorted leg both prevents motion in the affected direction an...
