About B2164

B2164 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 B2164 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 B2164 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 B2164 sets when the seat memory module detects that the stored memory position for the rear vertical (cushion rear height or rear tilt) motor is outside the expected operating range. The rear vertical motor position is monitored via either a hall effect encoder or a potentiometer feedback signal as the motor adjusts the rear edge of 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 accep...
