Alarm Troubleshooting

Alarm and Description Cause Solution

CA

Communication Error

The Display Module is not

communicating with the

Advanced Fluid Control

Module.

The CAN cable between the Display

Module and the Advanced Fluid Control

Module is not connected.

Verify that the cable is correctly con-

nected.

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

Module (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 module (See Alterna-

tor Module Power Output). If the

proper voltage is not detected, trou-

bleshoot 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.

CAU1

USB Communication Error

The system detected a USB

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.
