About B2130

B2130 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.

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 B2130 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

B2130 is set when the body control module (BCM) commands the double lock (also known as deadlock or superlock) feature but does not receive confirmation that the deadlock function has completed within the expected timeout period. Double locking is a security feature on many vehicles that, after a normal central lock command, drives the lock motor through a second stroke to mechanically disable the interior door handle, so the door cannot be opened from inside even if a window is broken. When the BCM commands deadlock and the actuator either fails to draw the expected current, stalls, or does n...
