BENDIX TABS6 Installation Instructions

Bendix
of Bendix
Prior to installation or performing service to ABS
controllers always perform the following steps:
1. Inspect the vehicle for damage, chafing, etc. to
current ABS unit, hoses or wiring and adjust routing of
replacement installation as necessary.
2. Turn power off.
3. Drain the air pressure from all reservoirs.
4. Remove as much contamination as possible prior to
disconnecting electrical connections and air lines.
5. Note the original controller assembly mounting position
on the vehicle.
6. Follow all General Maintenance Precautions as found
below in these instructions.
REMOVING THE ORIGINAL CONTROLLER
1. Disconnect the ECU connector and any modulator
connector from the controller.
2. Remove all air lines connected to the unit. (Use spray
lubricant on the swivel fi ttings of the delivery lines where
necessary before attempting to remove them.)
3. Remove the controller assembly from the vehicle by
removing the mounting bracket nuts or by rotating
the entire assembly counterclockwise from the tank
mount.
4. Disconnect the ABS sensors and remove the existing
harness. Bendix requires that only Bendix wheel speed
sensors be used for Bendix ABS systems.
WHEEL SPEED SENSOR REPLACEMENT
Due to the critical safety function provided by any ABS
product, Bendix does not assume responsibility for antilock
system reliability or performance issues in situations where
substitute non-Bendix ® ABS components, not supplied by
Bendix (for example, substituting a non-Bendix
speed sensor or modulator valve) are used on a vehicle
®
equipped with Bendix ABS. In addition, use of alternate
components in place of genuine Bendix components could
lead to rejection of ABS warranty claims. See Bulletin
TCH-013-009 for more details.
INSPECTION
Inspect the location selected for installation and clean as
necessary.
NOTE: Inspect all components, including the
replacement trailer ABS 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.
