Test System
Use a volt meter to check that the system has between 11 to 30 volts.
With the ignition on, switch the TractionAir ECU to on. Actual tyre pressure will
show on readout, unless there is no air pressure in the system.
With all tyre valves shut, open only two ball valves on one hub assembly.
This means we are only supplying and exhausting air from two tyres which will
speed up the pressure setting time. You are now ready to check each of the four
pre-set factory pressure settings. Start with the lowest setting. Push the lowest
setting (maximum traction) button.
NB Pressure can vary ± 2 PSI. Below is a common example of the pressure settings,
yours may vary depending on your requirement and specification at the point of sale.

Test each joint for air leaks using a squirt bottle with a mixture of dishwashing
liquid and water.
Check all air lines and electrical cables are securely cable tied and wrapped
where necessary to avoid chafing from vibration.
