OK -- REPLACE YAW RATE AND ACCELERATION SENSOR
Steering Angle Sensor Initialization Incomplete (to 12/2010)
BRAKE CONTROL: VEHICLE STABILITY CONTROL SYSTEM: C1440/98: Unusual Bank Angle Detected
C1440/98 - 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 C1440/98 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
C1440/98, after the vehicle is returned to a normal position.
HINT
DTC C1440/98 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.
