Troubleshooting Guide - Transfer Flow TRAXUFS User's Manual And Reference

Q
— The system does not work. The display does not light up.
A
— It sounds like the Transfer Flow system is not getting power. Find the Transfer
Flow control module under the dash. Is the green light illuminated? If not, check the
fuse located in the wire harness about six inches from the module.
Q
— The fuel levels displayed on the LCD change when cornering hard or during
other rapid motions. Is this normal?
A
— Yes and no. No matter what, fuel will slosh around in fuel tanks when the vehicle
is in motion. Your Transfer Flow fuel tank and system has been optimally designed to
keep fuel sloshing to a minimum. However, it is not possible to completely eliminate
all fuel sloshing. Many times, you will find that fuel sloshing will be greater in the
OEM tank than the Transfer Flow tank. This is because the Transfer Flow tank is fully
baffled while some OEM tanks are not. In either case, you should not see the fuel level
change more than four or five gallons, except under periods of high cornering, braking,
or acceleration loads.
Q
— My OEM fuel gauge is on empty and the Transfer Flow dash mounted LCD
shows that the OEM and auxiliary tanks are empty. The "Status" also shows a code
other than "OK". What is happening?
A
— The Transfer Flow system is telling you that there is a problem. The "Status" heading
should have a trouble code displayed. See Figure 3 to further troubleshoot the system.
Q
— My OEM fuel gauge is on empty and I know I have fuel in the system. I
didn't have the dash mounted LCD installed. What should I do?
A
— You need to connect the LCD into the system so you can diagnose the problem.
You should find the Transfer Flow control module under the dash. Locate the wiring
harness that connects to the module. The harness from the computer module branches
to an LCD harness with a 3-pin connector. Attach the LCD to this connector and the
LCD display should light up. See Figure 3 for information on the diagnostic trouble
codes. If you do not have the LCD display with you, locate the computer control module.
Two LED lights are on it. The green light tells you the system has power. The red light
is used for troubleshooting and can be used to diagnose problems by noting the number
of times the red light blinks. Refer to Figure 3 to find out what the number
of blinks mean and what each trouble code stands for.
