ECU/Valve Assembly
앫 12 volt
앫 Integrated ECU and ABS relay valve
앫 The 2S/1M Basic ECU/Valve Assembly does not
have an external diagnostics connector.
ABS External Valve
앫 Controls air pressure to the brake chambers
where it is plumbed.
앫 During ABS operation, the valve adjusts air
pressure to the brake chambers to control
braking and prevent wheel lock.
앫 Used in conjunction with ECU/Valve Assembly
for 2M or 3M systems.
Sensor with Molded Socket
앫 Measures the speed of a tooth wheel rotating
with the vehicle wheel.
앫 Produces an output voltage proportional to
wheel speed.
Sensor Spring Clip
앫 Holds the wheel speed sensor in close proximity
to the tooth wheel.
Sensor Extension Cable
앫 Two-wire cable with molded-on connector.
앫 Connects the wheel speed sensor to the ECU.
