Shift Motor Function

Attach voltmeter to A4 and A5. Have an assistant change shift positions. Voltage should increase for about 1 second and relay should click. If voltage is present, remove shift motor from transfer case and initiate another shift. Motor should rotate, replace motor if it does not rotate. If voltage is not present to motor, check power circuits and range sensors.

NOTE: If transfer case range sensors are providing incorrect data, control module will not power motor.
