ABS WIRING
Disconnect the electrical connectors from the ABS/
TRSP Controller before welding on the trailer.
Dielectric grease should be applied to electrical
connectors to help protect against moisture intrusion.
All connector leads of the Bendix TABS-6 module pigtail
harness are weather sealed at the connector interface and
are clearly labeled for proper installation.
Bendix provides over-molded versions of the Bendix
TABS-6 wiring harness and Bendix recommends that the
complete harness be replaced if corrosion or damage
occurs.
When troubleshooting ABS wiring, some general rules
should be followed where applicable.
1. Check all wiring and connectors to ensure they are
secure and free from visible damage (e.g. cuts,
abrasions, etc.).
2. Check for evidence of wire chafing due to poor routing,
or poor securing, of wires.
3. Check connectors for proper insertion and locking.
4. Verify that the connector pins are properly greased with
a non-conductive electrical grease compound.
5. Connector terminals must not show signs of corrosion
or exposure to the environment.
6. Never pierce wire insulation when checking for
continuity.
7. Do not deform individual pins or sockets during probing
with a volt/ohm meter.
8. It is strongly recommended to properly secure all wiring
harness and sensor leads at least every 18 inches.
9. Apply a moderate amount of non-conductive electrical
grease to each connector pin before reconnecting.
MISCELLANEOUS MAINTENANCE
GLAD HAND MAINTENANCE
▲
NEVER POUR ANy LIQUIDS
(alcohol, anti-freeze, additives,
etc.) into the glad hands. Liquids
may cause the o-rings and seals
to swell, may result in lubrication
loss and leave harmful residues.
▲
Prevent nesting insects and contaminants from
entering and blocking the air hoses. Check that
screens are present and clean.
▲
Drain the trailer air tanks a minimum of every six
(6) months.
Liquids/Contamination can cause TRAILER AIR
BRAKE FAILURE and/or the INABILITy TO RELEASE
the trailer parking brakes.

ABS SySTEM POWER-UP CHECK
At power-up the trailer ABS indicator lamp should
briefly illuminate “ON” as a bulb check.
If the indicator lamp does not illuminate at power-up,
the ABS system may not be powered, or the bulb may
need to be replaced. Service the trailer ABS system.
▲ If the lamp remains “ON” after power-up there
may be active Diagnostic Trouble Codes. Service
the trailer ABS system. (To ensure full ABS/TRSP
functionality, service as soon as possible.)
Other Important Practices:
▲ Follow all standard industry safety practices.
▲ Sealant for ABS Fittings: Use pre- or hand-applied;
Never PTFE tape (Voids Bendix ABS Warranty).
▲ Use open-ended clips (never cable ties) to hold
sensor leads to jounce lines.
▲ Drain the trailer air tanks a minumum of every six
(6) months.
▲ Disconnect the electrical connectors from the ABS
Controller when welding on the trailer.
