About B2161

B2161 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 B2161 is stored, the module has detected a plausibility fault — the measured value is in the electrical range but is not consistent with expected operating behaviour.

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 B2161 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

DTC B2161 sets when the seat memory module detects that the stored memory position for the front vertical cushion lift motor is outside the expected operating range. The vertical motor position is monitored via either a hall effect encoder or a potentiometer feedback signal as the motor moves the seat cushion up and down. When the driver attempts to recall a memory position, the module compares the stored target value against the current sensor reading and the known mechanical travel limits, and sets this code if the stored value falls outside acceptable bounds. When this code is active, the m...
