DTC C1440: Steering Angle Sensor Unusual Bank Angle Detected: Description
WARNING: This page is about a different car, the 2009 Lexus IS 350 and 2009 Lexus IS 250. However, it is still accessible from the selected car via links, so may be relevant.
If the skid control ECU determines that the vehicle is being driven at a steep bank angle, the skid control ECU stores DTC C1440 while VSC operation is temporarily disabled.
It is not a malfunction if the system and sensor circuits are normal and if the normal VSC operation resumes, which automatically clears DTC 1440, after the vehicle is returned to a normal position.
HINT:
DTC C1440 and the yaw rate and acceleration sensor DTC are stored when the skid control ECU determines that the vehicle is being driven at a steep bank angle and either of the following conditions is present:
- The yaw rate and acceleration sensor is installed at a titled angle.
- The yaw rate and acceleration sensor signal output is stuck.
