4. Check the TABS‑6 Adv MC module, modulator valve(s)
and all air hose fittings for leakage using a soap
solution.
Check the ABS solenoid body with the trailer service
brakes fully applied. If leakage is excessive — more
thanasingle1"bubblewithin1minute—replacethe
TABS‑6 Adv MC module.
Check the relay exhaust port with the trailer service
brakes released to be sure that leakage is less than
a single 1" bubble within 3 seconds.  If excessive
leakage is detected at the relay exhaust port, perform
the following test before replacing the TABS‑6 Adv MC
module:
• Apply the trailer spring brakes. Recheck for leakage
around the relay exhaust port. If the exhaust port
stops leaking, this indicates a leak between the
emergency and service sides of the spring brake
chamber. However, if the relay exhaust port
continues to leak excessively, replace the TABS‑6
Adv MC module.
5. Applypowerand monitorthe power-upsequence to
verify proper system operation. See Section 15.
6. Calibrate and set odometer parameters, if necessary,
using a diagnostic tool. See Section 16.
7. Perform an installation test using a diagnostic tool.
Minimum teststhat are required to verify the proper
installation of the ABS/TRSP system are:
• ECU Information: This test provides the user with
specic ECU information.  It is required that no
DTC’s(otherthan“end-of-linetestnotcompleted”)
arepresentandthattheECUhasbeencongured.
• Wheel End Sequence Test:  During thistest,
checks are carried out that verify the correlation of
the wheel installed with a Wheel Speed Sensor and
the Pressure Modulator that controls the pressure
to the associated brake.
• Lateral Acceleration Test: The installation angle
informationisretrievedfromtheECUandcompared
tothepredenedlimits(+/-5 degrees).Thistest
veriesthattheunitisinstalledasclosetohorizontal
as possible.
• Pressure Sensor Test: Duringthistest,checksare
carried out that verify that the proper response is
received from the pressure sensors during a brake
application.
• Axle Load Sensing Test (Air Ride): The test
has the user verify the expected measurement
of the load pressure sensor, Port 42, for air ride
suspensions. The program provides the reading
of the sensor.
