The tester should sound a tone and illuminate a green light when each button is pressed. ? If any of the buttons do not sound the tone and illuminate the green light, replace the transmitter battery. Retest with the J 43241 . If the transmitter continues to malfunction, replace the affected transmitter.
  3. Verify the scan tool Fob Programmed parameter for the transmitter being used is Yes. ? If not the specified value, program the applicable transmitter.
