Function
Technical Features
Operating Temperature Range:
-40 °C to +80 °C
See tables for other features.
Cables
are used in trailer ABS systems to:
• provide electrical power to the components in the
system.
• communicate signals to the ECU from sensors
monitoring trailer characteristics.
• communicate control commands from the ECU
to modulators to enable any required braking
intervention.
• communicate faults signals to the towing vehicle.
Power Supply Cables
are used to distribute electrical
power from the towing vehicle to electrically powered
braking and auxiliary equipment on the trailer. The main
power supply to the trailer is through a plug or socket
according to ISO 7638.
The cables are available in various lengths.
Modular Cables / Wiring Harnesses
are available in many configurations and are used to supply electrical signals
and power to auxiliary equipment including the external third modulator on 4S/3M systems.
Wheel Speed Sensor Cables
are used to connect the ECU to the wheel speed sensors so that their wheel speed
signals can be sent. The wheel speed sensor is supplied with only a short length of cable and so will often require a
Wheel Speed Sensor Extension Cable
to enable connection.
NOTES:
The text in the ‘Comments’ columns describes the typical usage. Other connections are
possible for most cables.
