Steering Angle Sensor Unusual Bank Angle Detected (C1440)

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 C1440, 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 met:

• The yaw rate and acceleration sensor is installed at an angle.
• The yaw rate and acceleration sensor signal output is stuck.

1. CHECK DTC

(a) Clear the DTCs (See page ).

(b) Perform a road test.

(c) Check if the same DTC is output (See page
