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.

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.
