System DescriptionUnusual Bank Angle Detected (C1440)
DESCRIPTION
If the skid control ECU (brake actuator assembly) determines that the vehicle
is being driven at a steep bank angle, the skid control ECU (brake actuator assembly)
stores DTC C1440 while VSC operation is temporarily disabled.
This is not a malfunction if the system and sensor circu ...
