SERVICING THE BENDIX ®
TABS‑6 ™ ADV MC MODULE
CAUTION: Special considerations need to be
taken to ensure that the Bendix ® TABS‑6 ™ Adv MC
module has been properly installed on the trailer.
These include:
• Location and orientation of the module.
• Correct plumbing of the module.
• Correct deflection sensor installation (where used).
• Correct location of the wheel speed sensors.
• Configuration of the ECU for ABS & Bendix
® TRSP ®
system parameters.
• Installation Test to verify proper installation of the
ABS/TRSP system.
Incorrect installation of the TABS‑6 Adv MC module
system can result in impaired ABS & TRSP system
functions. It is the responsibility of the end‑user to
ensure that the TABS‑6 Adv MC module system has
been installed correctly and tested as per the Bendix
recommended installation guidelines and system
drawings.
Prior to performing service to the TABS‑6 Adv MC module,
always perform the following steps:
1. Follow all industry safe maintenance practices including
those on page 2 of this document.
2. Ideally, before removing the module, use Bendix ®
ACom ® diagnostic software to save the configuration
to the desktop. (After the module has been replaced,
the technician can restore the previous configuration
settings.)
3. Turn the power off.
4. Drain the air pressure from all reservoirs.
5. Remove as much contamination as possible prior to
disconnecting electrical connections and air hoses.
6. Note the TABS-6 Adv MC module's mounting position
on the vehicle.
REMOVING THE TABS‑6 ADV MC MODULE
1. Open the end covers by sliding the locking tabs to the
left. If the module is to be reinstalled, retain the covers.
2. Disconnect the 7-pin ECU connector, the 12-pin
auxiliary/diagnostic harness (if present) and the two to
four 2‑pin wheel speed sensor connectors, depending
on the configuration.
3. Mark for reinstallation and then remove all air hoses
connected to the TABS‑6 Adv MC module.
4. Remove the TABS‑6 Adv MC module from the vehicle
by removing the mounting fasteners.
SERVICING THE CONTROL PORT FILTER
CAUTION! The TABS‑6 Advanced MC module
has an in-line filter in the control port (see Figure 2).
This filter should be inspected and cleaned (if any
contamination is found), every four months, 34,000
miles or 1,200 operating hours. For severe applications,
this inspection interval may be reduced. If the filter is found
to be damaged, install a replacement. The filter should
also be inspected as part of any troubleshooting where
the service brakes are slow to apply and other possible
causes have been ruled out.
REINSTALLATION OF THE BENDIX ® TABS‑6 ™
ADV MC MODULE
CAUTION! All service replacement parts for the
Bendix ® TABS‑6 ™ Adv MC module are configured
specifically by part number.
As mentioned during the Servicing the bendix tAbS-6
Adv mc module step, ideally, before removing the
module, use Bendix ® ACom ® diagnostic software to
save the configuration to the desktop. The technician
can use ACom diagnostics to restore the previous
configuration settings.
Always verify that the correct service replacement ECU
is being installed by verifying that the part number is
the same as the original TABS‑6 Adv MC module. To
verify proper installation, perform the Installation Test
using the Bendix ACom diagnostic software (version
6.1 or higher) or use the Bendix ® Trailer Information
Module.
Inspect the original mounting hardware: If it is in good
condition, it can be reused for installation. If replacement
hardware is needed, use Class 8 steel M10 x 1.5 nuts and
lock washers for frame‑mounting.
Inspect the location selected for installation and clean as
necessary.
NOTE: Inspect all components, including the replace‑
ment TABS‑6 Adv MC module, for any external damage,
such as cracked valve ports, electronic housings, etc.
Any components found to be damaged should not be
installed on the vehicle and must be replaced.
