CLS Failed Low
OK you experts our there!
My neighbor experienced an alarm on his Detroit Pro panel that stated” CLS Failed Low”. I can only guess that it means Coolant Sensor Failed Low, again guessing the computer has sensed the sensor is shorted or open? He stated he received the alarm and was still able to normally drive without any issues. He did check the coolant tank level in the rear and all looked good.
I also guess, a new coolant sensor would be the first step in troubleshooting?
I hate to guess among the giants in the Prevost world, it seems to always turn out not good.
Any Ideas? -

Based on that I suspect the code is 13 and it suggests the voltage is low. If coolant is low it would be 43 and that does not read as you described. If the codes can be given a numeric value by flashing them it would clear up the question.
Dirty or corroded terminals? Damaged wire? Bad sensor?
