DTC B2090: Driving Support System Malfunction [08/2015 - 08/2019]: Description
The seat belt control ECU receives collision information from the driving support ECU and skid control ECU via CAN communication and tightens the seat belt by operating the motor inside the front seat outer belt.
When the driving support ECU detects a malfunction in the dynamic radar cruise control system or pre-collision system (Pre-Collision 2), the malfunction information is sent to the seat belt control ECU, which stores this DTC.
When DTC B2090 is stored, other DTCs stored by the driving support ECU (dynamic radar cruise control system, lane departure alert system* and Pre-Collision 2) are also stored.
