POWERSHIFT SPEED SENSOR TEST
Disconnect from control valve and fit the 12 pin con-
nector from special tool.
Connect the power socket to the 12 V socket.
Install the probes from a multimeter into the tool.
Raise the unit off the ground and observe voltage
(V1). Turn the rear wheel which in turn rotates the
transmission output shaft, observe the second volt-
age (V2).
Test procedure
The special tool connects to pin A speed sensor plus
output, and pin J speed sensor/temperature sensor
ground.
