Differential Pressure Switch Replacement

1. With the ignition key in the OFF position, discharge the ABS accumulator by pumping the brake pedal a minimum of 40 times.

2. Disconnect the primary pressure transducer connector which will expose the differential pressure switch connector.

3. Disconnect the differential pressure switch connector from the ABS harness, not at the switch.

NOTE:
THE CONNECTOR IS MOLDED ON AT THE SWITCH.





4. Remove the differential pressure switch and connector from the actuator housing (Figure 1).

5. Install the new differential pressure switch into the actuator housing. Tighten to 1.35 - 1.81 N-m (12 - 16 in.lbs.).

6. Connect the differential pressure switch connector and the primary pressure transducer connector.
