About B1361

B1361 is a manufacturer-specific body diagnostic trouble code. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B1361 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.

B1361 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

DTC B1361 is set by the Body Control Module (BCM) when it detects battery voltage on its Run/Accessory input pin while the ignition switch is in the OFF position. The BCM expects this input to be near 0V with the key off and to rise to battery voltage only when the switch is moved to ACC or RUN, so a continuous voltage with the key off indicates the circuit is being back fed or shorted to a constant power source. The most common physical cause is a chafed wire between the ignition switch and the BCM that has rubbed against an always-hot conductor, or a failed ignition switch where the contact ...
