1. TheTABS-6AdvMCmoduleshallbeinstalledwiththe
followingconsiderations(seeFigures16through18):

FIGURE 17 ‑ INSTALLATION ON TRAILER (LONGITUDINAL)
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 congured for an offset).

FIGURE 18 ‑ INSTALLATION ON TRAILER (CENTER LINE)
• With exhaust port facing downward and unobstructed
withsignicant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veried
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at
horizontal plane.
• Roll angle shall be within ± 5° as measured from a
at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
Teon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ttings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xed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x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.
