Before I would be jumping on the crank sensor, I would be checking the battery/charging Voltage.

You should be able to bring up the Hidden OBC Menu and be able to monitor you Voltage directly on the OBC display.

Crazy battery/charging Voltage can generate some strange faults and cause the dashboard to light up like a Christmas tree!

Would have never believed this until I witnessed it first hand.
