DTC B2090: Driving Support System Malfunction [09/2015 - ]: Description
The seat belt control ECU receives collision information from the driving support ECU assembly and skid control ECU assembly via CAN communication, and tightens the seat belt by operating the motor inside the front seat outer belt assembly.
When the driving support ECU assembly detects a malfunction in the dynamic radar cruise control system, and pre-collision system ("Pre-Collision 2" part), or detects that the object recognition camera has not been adjusted, the malfunction information is sent to the seat belt control ECU, which outputs this DTC.
When DTC B2090 is detected, other DTCs output by the driving support ECU assembly (dynamic radar cruise control system, Pre-Collision 2) are also output.
HINT:
If the object recognition camera is replaced with a new one and the adjustment of the object recognition camera has not been performed, DTC B2090 is output.
