VEHICLE STABILITY CONTROL SYSTEM, Diagnostic DTC:C1440

DTC Code DTC Name
C1440 Steering Angle Sensor Unusual Bank Angle Detected

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 circuits are normal and normal VSC operation resumes.

      Tech Tips


      • 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.

      • If DTC C1440 is automatically cleared after the vehicle returns to a normal bank angle and no malfunctions are detected, DTC C1440 was not stored due to a malfunction.
