|
DTC |
C1440 |
Unusual Bank Angle Detected |
DESCRIPTION
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 present:
- The yaw rate and acceleration sensor is installed at a tilted angle.
- The yaw rate and acceleration sensor signal output is stuck.
