The control module has 2 internal 5v reference rails called voltage references 1 and 2 or A and B
There are also more reference rails.
Each reference rail provided a 5v reference circuit for more than one sensor.
Therefore, a fault condition in one 5v reference circuit will affect other 5v reference circuit sensors connected to the bus.
The control module monitors the 5v voltage on reference rails A and B
Scheme and multimeter to hand and to work
