SERVICING THE BENDIX ®
TABS‑6 ™ ADV MODULE
CAUTION: Special considerations need to be
taken to ensure that the Bendix ® TABS‑6 ™ Adv 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 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 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 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 module's mounting position on
the vehicle.
REMOVING THE TABS‑6 ADV MODULE
1. Open the end cover by sliding the locking tab to the
left. If the module is to be reinstalled, retain the cover.
2. Disconnect the 18-pin ECU connector and the two 2-pin
wheel speed sensor connectors.
3. Mark for reinstallation and then remove all air hoses
connected to the TABS‑6 Adv module.
4. Remove the Advanced module from the vehicle by
removing the mounting fasteners or by rotating the
entire assembly counter‑clockwise from the tank mount.
SERVICING THE CONTROL PORT FILTER
CAUTION! The TABS‑6 Advanced 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 MODULE
CAUTION! All service replacement parts for
the Bendix ® TABS‑6 ™ Adv module are configured
specifically by part number.
As mentioned during the Servicing the Bendix TABS-6
Adv 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 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 Grade-5 3/8-18 bolts, nuts and
lock washers for the frame-mount unit, or a schedule 80
(heavy gauge steel) ¾” nipple for the tank‑mount unit.
Inspect the location selected for installation and clean as
necessary.
NOTE: Inspect all components, including the replace‑
ment TABS‑6 Adv 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.
