DTC |
C1440 |
Steering Angle Sensor Unusual Bank Angle Detected |
DESCRIPTION
If the skid control ECU (brake booster with master cylinder assembly) determines that the vehicle is being driven at a steep bank angle, the skid control ECU (brake booster with master cylinder assembly) stores DTC C1440 while VSC operation is temporarily disabled.
This is not a malfunction if the system and sensor circuits are normal and if normal VSC operation resumes.
