- [A451206 2031989\-](/bulletins/10122679.md), 2017-11-08, Service bulletin: EXTERIOR LIGHTING:BRAKE LIGHTS; EXTERIOR LIGHTING:BRAKE LIGHTS:SWITCH. After replacing the ABS control unit, the new control unit stores DTC 01044 \(Control Unit Incorrectly Coded\). No warning light is on and the brake electronics work correctly. Due to a supersession of parts, only ABS/ESP hydraulic control units prepared for vehicles equipped with the start\-stop feature are supplied as replacement parts. Once installed, the new unit stores DTC 01044 \(Control Unit Incorrectly Coded\) because it does not receive a response on the data bus when checking for the start\-stop feature. The missing response results in the DTC entry. Within the scenario described in the Condition section of this TSB, the missing start\-stop response is the only reason for this DTC. In all other respects the coding of the ABS/ESP control unit matches the vehicle data. The entry does not affect the function of the brake electronics and no warning appears in the instrument cluster. There are no effects on performance or safety.
