About B0016

B0016 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 B0016 is stored, the module has detected a signal or supply voltage lower than the expected operating range.

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 B0016 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 Restraints Control Module (RCM) continuously measures the resistance of the right hand front (RHF) seatbelt pretensioner deployment loop, which must stay within a defined window that represents a healthy initiator and clean wiring. DTC B0016 sets when that loop resistance falls below the expected range, which usually means a partial short between the deployment wires, a short to ground, or a degraded pretensioner element. Low loop resistance can change the current delivered to the initiator and could disturb the timing or reliability of pretensioner firing. While the code is stored the RCM...
