3-315 IOT/IPS Communications Fail RAP
The 3-315 Fault Code indicates that a communication failure between the IOT PWB and the
Post IPS PWB was detected.
Initial Actions
•
Ensure that
P571
is firmly connected to the Post IPS PWB.
•
Refer to BSD 3.2 PWB Communications (IPS) and BSD 3.12 Monitoring in this proce-
dure:
Procedure
There is +3.5 VDC from J 570 pin 1 to pin 6 on the Post IPS PWB.
