FSM Invalid Data Received From Steering Angle Sensor Module. Algorithm Based Failures. Event Information
FSM Invalid Data Received From Steering Angle Sensor Module. Algorithm Based Failures. Event Information
Description
The control module is continually supplied with necessary information from the Steering wheel angle sensor module (SAS) via CAN communication. The control module checks the quality of the information from the Steering wheel angle sensor module (SAS). The diagnostic trouble code (DTC) is stored if the control module detects that: Transmitting control module indicates a lower quality level of the information than what Forward Sensing Module (FSM) accepts. The control modules test for the diagnostic trouble code (DTC) starts in the event of: Engine running. Note! The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met.
Cause and Solution
Fault-trace the Steering wheel angle sensor module (SAS).
