Solution
Insert a system token into
the missing GCA module
and cycle the power. Wait
until the red light on the
module to stop flashing
before removing the token.
Verify the dial on the TCM's
are in the correct position:
0 for hose, A for boost A,
B for boost B
Green light on each
module should be lit. If
green light is not lit, check
to make sure each CAN
cable connection is tight.
Verify the power supply is
outputting 24 Vdc. If not,
replace power supply. See
System Repair manual.
Check the CAN cables
running between GCA
modules and tighten if
needed. If the problem still
persists move each cable
around the connector and
watch the flashing yellow
light on the GCA modules.
If the lights stops replace
the CAN cable.
Replace MCM. See
System Repair manual
for instructions.
Replace Remote Display
Module.
