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 fittings 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
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.
INSTAllATION
1. Position and secure the ABS unit in the original mounting
orientation: (The exhaust port must point straight down.)
Tank (nipple) mount unit - Install the nipple fitting into the
ABS module supply port. Then rotate the entire assembly
into the tank port until secure. Over-torquing of the tank
nipple could cause damage to the Module.
