1.5 ABS Connection

1.5.1 General

The easiest method of linking into the ABS sensors is to locate the controller. This

may look like an engine ECU or be combined with the ABS pump.

ABS Pump and Controller ABS Unit

Most ABS sensors are passive inductive sensors that give a signal when metal

passes near them. Resistance of sensors varies from 800 - 1200 ohms. Sensors

usually have two wires each, which account for eight wires feeding the ABS unit.

These wires have to be located and four wires from the traction control have to be

connected to one side of each sensor. Deciding which wire to connect to is

dependent upon the type of sensor used, Diagram 7.

Diagram 7 - ABS Sensors

In the first example sensor A, one of the wires is connected to the shielding of the

cable (pin 12), the traction control wire must be connected to the wire connected into

pin 11. In the second example sensor B, both wires carry signals to the ABS,

therefore the traction control can be connected to either wire.
