GENERAL
The initial release of the Bendix® TABS-8™ Advanced SingleChannel Module did not include a Low Pressure Warning
Emergency (LPWE) configured by default. This aftermarket
service kit is configured (by default) with LPWE. If replacing
an older revision of the TABS-8 Advanced Single-Channel
Module with the new aftermarket service kit, it will be necessary
to add a shorting cap (Bendix Part Number K148792) to the
S-E connector input.
When working on or around a vehicle, the following
guidelines should be observed AT ALL TIMES:
▲Park the vehicle on a level surface, apply the parking
brakes, and always block the wheels. Always wear personal
protection equipment.
▲Stop the engine and remove the ignition key when working
under or around the vehicle. When working in the engine
compartment, the engine should be shut off and the ignition
key should be removed. Where circumstances require that
the engine be in operation, EXTREME CAUTION should be
used to prevent personal injury resulting from contact with
moving, rotating, leaking, heated, or electrically charged
components.
▲Do not attempt to install, remove, disassemble, or
assemble a component until you have read, and thoroughly
understand, the recommended procedures. Use only the
proper tools and observe all precautions pertaining to use
of those tools.
▲If the work is being performed on the vehicle’s air brake
system, or any auxiliary pressurized air systems, make
certain to drain the air pressure from all reservoirs before
beginning ANY work on the vehicle. If the vehicle is
equipped with a Bendix® AD-IS® air dryer system, a Bendix®
DRM™ dryer reservoir module, a Bendix ® AD-9si ®, AD-HF®,
or AD-HFi™ air dryer, be sure to drain the purge reservoir.
▲Following the vehicle manufacturer’s recommended
procedures, deactivate the electrical system in a manner
that safely removes all electrical power from the vehicle.
▲Never exceed manufacturer’s recommended pressures.
▲Never connect or disconnect a hose or line containing
pressure; it may whip and/or cause hazardous airborne
dust and dirt particles. Wear eye protection. Slowly open
connections with care, and verify that no pressure is
present. Never remove a component or plug unless you are
certain all system pressure has been depleted.
▲Use only genuine Bendix ® brand replacement parts,
components, and kits. Replacement hardware, tubing, hose,
fittings, wiring, etc. must be of equivalent size, type, and
strength as original equipment and be designed specifically
for such applications and systems.
▲Components with stripped threads or damaged parts should
be replaced rather than repaired. Do not attempt repairs
requiring machining or welding unless specifically stated
and approved by the vehicle and component manufacturer.
▲Prior to returning the vehicle to service, make certain all
components and systems are restored to their proper
operating condition.
▲For vehicles with Automatic Traction Control (ATC), the ATC
function must be disabled (ATC indicator lamp should be
ON) prior to performing any vehicle maintenance where
one or more wheels on a drive axle are lifted off the ground
and moving.
▲The power MUST be temporarily disconnected from the
radar sensor whenever any tests USING A DYNAMOMETER
are conducted on a vehicle equipped with a Bendix ®
Wingman ® system.
▲You should consult the vehicle manufacturer's operating
and service manuals, and any related literature, in
conjunction with the guidelines above.

SHORTING CAP INSTALLATION
The aftermarket service kit includes one (1) Electronic Control
Unit (ECU), and one (1) shorting cap pre-installed on the S-F
connector, a pre-configured pad wear sensing input. There
will also be a loose shorting cap that needs to be installed
on the S-E connector if the trailer is not equipped with the
Low Pressure Warning Emergency (LPWE) feature.
See Figure 1.
1. Remove the electrical cover to access the electrical
connectors.
2. Install the shorting cap onto the S-E connector by aligning
the key inside the shorting cap connector. Use the keyway on the S-E connector on the electrical header of
the ECU.
Ensure the shorting cap is fully seated. If the shorting
cap is not fully seated, the electrical cover will not be
able to be installed properly.
Refer to Table 1. If replacing the following Original
Equipment Manufacturer (OEM) parts, a shorting cap
must be added to the S-E connector. Failure to add a
shorting cap to the S-E connector will result in an active
LPWE Diagnostic Trouble Code (DTC) that will illuminate
the Antilock Braking System (ABS) light. Additionally,
if the shorting cap is not installed, the pins on the S-E
connector will be exposed to the environment and
will develop corrosion over time. S-E connectors with
exposed pins are not covered by the standard Bendix
warranty.
