About B2246

B2246 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 B2246 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 B2246 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) monitors the passenger sliding door ajar switch circuit to determine whether the door is open or closed. DTC B2246 is set when the BCM detects the ajar signal circuit shorted to ground, meaning the input is being pulled low when the door is closed and the BCM expects a normal pulled high state. The ajar switch is built into the sliding door latch assembly and the signal wire travels through a flexible articulating harness loop between the body and the door. When this code is set, the BCM will continuously think the passenger sliding door is open, keeping interior ...
