Release Date:
November 2021
Symptom/Vehicle Issue: U0422-64 Set In The FFCM/HALF Module. Lane Departure
And Blindspot Warning Displayed In The Cluster
Discussion: A warning for the Lane Departure and Blindspot systems may be
displayed in the instrument cluster. Upon scanning the vehicle for DTC’s you may find
U0422-64-Body Control Module-Signal Plausibility Failure goes from Stored to Active
as the steering wheel is moved. This could be caused by an issue with the steering
wheel sensor that detects hands are on the steering wheel.
Diagnosis: To confirm this is the root cause of the issue. Using WiTech access the
BCM and then Data. Search “Hands On Sensor Management”. The parameter is
supposed to indicate “Hands_On_Detected” or “Hands_Off_Not Dectected”. If the
steering wheel is moved or touched and the parameter reads “Hands_Off_Error”,
the concern is caused by the steering wheel sensor.
