SAFE MAINTENANCE PRACTICES
WARNING! PLEASE READ AND FOLLOW
THESE INSTRUCTIONS
PERSONAL INJURY OR DEATH:
When working on or around a vehicle, the following
general precautions should be observed at all times:
1. Park the vehicle on a level surface, apply the
parking brakes, and always block the wheels.
Always wear safety glasses.
2. Stop the engine and remove 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.
3. 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.
4. 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 an AD-IS
air dryer system or a dryer reservoir module, be
sure to drain the purge reservoir.
5. Following the
recommended procedures, deactivate the electrical
system in a manner that safely removes all
electrical power from the vehicle.
6. Never exceed manufacturer's recommended
pressures.
7. Never connect or disconnect a hose or line
containing pressure; it may whip. Never remove a
component or plug unless you are certain all
system pressure has been depleted.
8. Use only genuine Bendix
components and kits. Replacement hardware,
tubing, hose, fittings, etc. must be of equivalent
size, type and strength as original equipment and
be designed specifically for such applications and
systems.
9. 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.
Troubleshooting: General
TO AVOID
vehicle manufacturer's
®
replacement parts,
10. Prior to returning the vehicle to service, make
certain all components and systems are restored
to their proper operating condition.
11. For vehicles with Antilock 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.
REMOVING THE EC-60
ASSEMBLY
1. Turn vehicle ignition off.
2. Remove as much contamination as possible prior to
disconnecting air lines and electrical connections.
3. Note the EC-60
on the vehicle.
4. Disconnect the electrical connectors from the EC-60
controller.
5. Remove and retain the mounting bolts that secure the
EC-60 ™ controller.
INSTALLING A NEW EC-60
CAUTION! When replacing the EC-60
that the unit you are installing has the correct default
settings. Failure to do so could result in a loss of features,
such as ATC and PLC, or noncompliance with U.S.
regulations such as FMVSS 121. It is recommended to
use only the correct replacement part number. However,
®
most configuration settings can be altered using the Bendix
™
ACom ABS Diagnostic Software program.
Verify correct operation of the EC-60
and indicator lamps prior to putting the vehicle back into
service. Towing vehicles manufactured after March 1, 2001
must support the trailer ABS indicator lamp located on the
dash.
For further information, contact either the vehicle
manufacturer, Bendix or your local authorized Bendix dealer.
1. Position and secure the EC-60
mounting orientation using the mounting bolts retained
during removal. On frame-mount ECUs, torque the
mounting bolts to 7.5 to 9 NM (66-80 in. Ibs). For cab-
mount units use no more torque than is necessary to
firmly secure the ECU into position. Over-tightening
the mounting hardware can cause damage to the EC-60
controller.
2. Reconnect the electrical connectors to the EC-60
controller.
3. Apply power and monitor the EC-60
up sequence to verify proper system operation.
