Communication Error
The Display Module is not
communicating with the
Advanced Fluid Control
Module.
The CAN cable between the Display Mod-
ule and the Advanced Fluid Control Module
is not connected.
Verify that the cable is correctly
connected.
The CAN cable is cut or bent. Verify that the cable has not been cut
or bent at a radius smaller than 1.6 in.
(40 mm).
The cable or connector failed. Replace cable.
Alternator Powered Systems:
Check that the Advance Fluid Control Mod-
ule (AFCM), Display Module (DM), and
USB Module have power (green LED) and
are communicating (amber LED blinking)
1. For any module that does not
have power, disconnect and
check the voltage on the cable
produced by the alternator mod-
ule (See Alternator Module Power
Output). If the proper voltage is
not detected, troubleshoot the
Alternator Module.
2. If the proper voltage is detected,
verify the cable connecting the
two modules is good.
3. If the cable is good, replace the
module.
There may be a short in one of the sole-
noid/meter cables connected to the AFCM.
Replace the cable (16E890)
The AFCM power supply may be bad, as
indicated by the status LEDs (red, yellow,
green) being off. Verify the power supply
works by disconnecting from the AFCM and
connecting to another module, either the
Display Module or USB Module.
Replace the module.
The DM and the AFCM have different ver-
sions of software installed.
Install the latest software from token
kit 16D922 on all modules.
The red LED on the AFCM is on. If on solid, replace module.
If blinking, contact your distributor.
NOTE:
1. If the AFCM loses communication (no flickering amber LED) but then comes
back on the alarm will auto clear and will not log the alarm.
2. If the DM loses communication (no flickering amber LED) but then comes back
on you will have to manually clear the alarm and there will be an alarm log.
3. If the USB module loses communication (no flickering amber LED) but then
comes back on you will not get an alarm.

Module at last power up, but
does not detect it currently.
The module has been removed. Put system in standby and install the
USB Module.
The cable is disconnected or broken. Put system in standby and reconnect
or replace the USB cable.
