DTC B2090: Driving Support System Malfunction [09/2014 - 10/2015]: 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 assembly.
When the driving support ECU detects a malfunction in the cruise control system, dynamic radar cruise control system, lane-keeping assist system, and pre-collision system ("Pre-Collision 2" part), or detects that the lane recognition camera sensor 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 (cruise control system, dynamic radar cruise control system, lane-keeping assist system, Pre-Collision 2) are also output.
HINT:
If the object recognition camera sensor is replaced with a new one and the adjustment of the object recognition camera sensor has not been performed, DTC B2090 is output.
| DTC Code | DTC Detection Condition | Trouble Area |
|---|---|---|
| B2090 | While the initial check is running, the engine switch is on (IG) and the pre-collision system is operating, the driving support ECU detects a malfunction for 1 second or more, or the state in which the lane recognition camera sensor assembly beam axis adjustment has not been performed is detected for 1 second or more. |
