System Set-up<br />
Setting Tire Pressure Target<br />
After completing the installation, the system’s tire pressure<br />
target must be set before using the trailer. On power-up, the<br />
lamp will remain on as an indication that the target pressure<br />
has not been set.<br />
There are two methods for setting the system’s tire pressure<br />
target:<br />
• System Learn Method – all tire pressures are set to<br />
the cold tire pressure setting and the system reads<br />
the tire pressure target<br />
• Service Tool Method – a service tool (PC-based or<br />
hand-held) is used to “download” the target over the<br />
data link.<br />

System Learn Method<br />
In order to set the target tire pressure using this method, all<br />
the tires must be verified to be at the target pressure for an<br />
accurate setting. Use the procedure in How to Manually Check<br />
Tire Pressures to measure and set the cold tire target pressure<br />
for all tires.<br />
1. Apply 12 volt power to the trailer at the SAE J560<br />
connector.<br />
2. Provide adequate pressure to the brake supply tank.<br />
(Minimum of desired tire target pressure +5 psi or<br />
90 psi, whichever is greater.) Note: Older systems<br />
with ECU P/N 676351 require a minimum supply of<br />
110 psi to program.<br />
3. Remove the weather cap from the diagnostic connector.<br />
Short pins “A” and “E” in the following<br />
sequence: short the pins three times, maintaining<br />
the short for approximately 1 second on and waiting<br />
1 second off. The pins to be shorted can be easily<br />
identified by the interconnecting slot in the shell,<br />
allowing convenient use of a coin or screwdriver tip<br />
to short the pins together.<br />
4. Upon entering learn mode, the warning lamp will<br />
turn on for 2 seconds twice and will then flash once<br />
every 10 seconds to acknowledge that the learn<br />
mode is active.<br />
5. The system will pressurize the air lines for several<br />
seconds, and then wait for the pressure to stabilize.<br />
6. The tire pressure read will be stored as the target<br />
pressure. Once the target pressure is established,<br />
the warning lamp will turn ON continuous for 5 seconds<br />
and then flash out the target pressure. For<br />
example, if the tire pressure is 102 psi, the light will<br />
turn ON continuous for 5 seconds and then flash 1<br />
time, pause and then flash 10 more times, pause and<br />
then flash 2 more times (0 is represented by 10<br />
flashes). If the value flashed is lower than the desired<br />
target pressure, verify that all the tires are set to the<br />
proper pressure and that no line leaks are present.<br />
7. After the system has determined the target pressure,<br />
it will remain pressurized for up to 2 minutes (or<br />
until power is cycled). During this time, a manual<br />
check for air leaks should be made.<br />
If a line leak is detected, the system will not pro<br />
gram a target pressure and warning lamp will turn<br />
on solid. If this occurs, correct the leak(s) and then<br />
set all tires to the target pressure and conduct the<br />
learn sequence again.<br />
Note: The system is only pressurized for two minutes following<br />
the attempted target learn. A leak will only be<br />
audible during this time.<br />
