the tAbS-6 Adv mc module must be located no
more than 40 inches from the mid-point between
the axles, and within two inches from the center
line of the trailer (unless configured for an offset).

• With exhaust port facing downward and unobstructed
with significant free space below (> 1 inch).
• Within ± 40" of the center of the axle(s) for proper
balanced brake applications.
• Within ± 2" from the center line of the trailer (default).
Note, a left/right offset greater than ± 2" may have
been programmed in the ECU and can be verified
using Bendix ACom diagnostic software (version
6.1 or higher).
• Yaw angle shall be ± 10° as measured from the
center line of the trailer.
• Pitch angle shall be ± 10° as measured from a flat
horizontal plane.
• Roll angle shall be within ± 5° as measured from a
flat horizontal plane.
Frame‑mount module: The TABS‑6 Adv MC module
uses three Class 8 steel M10x1.5 nuts with lock washers,
torqued to 354 ±44.4 in.-lbs (40±5 Nm).
2. Reconnect all air hoses and plugs to the module.
Depending on the installation, additional plugs may
be necessary. Thread sealant products that contain
Teflon may be used, however thread sealant tape is not
recommended as there is a potential for tape material
entering the valve and affecting the valve’s operation.
Make certain that no thread sealant enters the valve.
All air hoses and fittings should be checked for leaks
prior to returning the vehicle to service.
3. Reconnect the ECU power, auxiliary if present and
wheel speed sensor electrical connectors to the ECU.
Apply a moderate amount of non‑conductive electrical
grease to each connector pin before reconnecting.
Note: The wheel speed sensors must follow the orienta‑
tion of the module as shown in Figure 19 for fixed axle
trailers. Where a lift axle is present, and sensors are
to be installed on that axle, secondary sensors SE and
SF must be used for the lift axle.
• It is necessary to fix the wheel speed sensors to
the orientation of the lateral acceleration sensor for
plausibility checks between the sensors.
• If the wheel sensor location does not match the
orientation of the Bendix ® TABS‑6 ™ Adv MC module
shown in Figure 19, a Diagnostic Trouble Code
(DTC) will be generated and the ABS indicator lamp
will be illuminated.
• Refer to the raised lettering on the top cover for
wheel speed designation, “S-C”, “S-D”, “S-E”, and
“S‑F”.
4. Leakage and Operational Tests must be performed
before returning the vehicle to service.
LEAKAGE AND OPERATIONAL TESTS
1. Before performing the leakage tests, block the wheels.
2. Fully charge the air brake system and verify proper
brake adjustment.
3. Make several trailer brake applications and check for
prompt application and release at each wheel.
