Checking wiring and terminals
Check the wiring between the control module for the steering wheel angle sensor
terminal #3 (terminal (#A27) and steering wheel module (SWM) terminal #5 (terminal #A5)
terminal #4 (terminal (#A28) and steering wheel module (SWM) terminal #3 (terminal #A3)
terminal #10 (terminal (#A34) and steering wheel module (SWM) terminal #2 (terminal #A2)
#11 (#A35) and steering wheel module (SWM) #17 (#A17)
check for an intermittent short-circuit to each other.
Remedy as necessary.
