ANTILOCK BRAKING SYSTEM (ABS)
The antilock braking system has one Electronic
Control Unit (ECU) controlling a four channel
system. A wheel slip sensor is mounted at each
front axle and drive axle wheel. The Tag axle
wheels are slave to the drive axle wheels.
The Electronic Control Unit
(ECU) is
maintenance free. Its operating voltage is 24 ±
6 volts DC. The thermal operating range for the
ECU is from -40 to 167°F (-40 to 75°C).
The solenoid control valves are maintenance
free. Their operating voltage is 24 (+4.8, -2.4)
volts DC. The rated current draw is 1.65 amps.
The thermal operating range of the solenoid
control valves is from -40 to 176°F (-40 to 80°C).
