    • If not the correct transmitter, replace the transmitter.
  2. Verify the scan tool FOB Programmed parameter for the appropriate transmitter is Yes.
  3. Place the transmitter on the test pad of the J 43241  and press each transmitter button one at a time. See Special Tools . The tester should sound a tone and illuminate a green light with each button press.
    • If one or more buttons does not sound the tone and illuminate the green light, replace the transmitter battery and retest with the J 43241  . See Special Tools . If the condition continues after battery replacement, replace the transmitter.
  4. Operate the transmitter while observing the scan tool Fob Function parameter for the appropriate transmitter. The parameter should correspond with the function selected on the transmitter.
    • If the parameter does not match the function selected on the transmitter, replace the transmitter.
  5. Attempt to program the transmitter, refer to Remote Control Door Lock Transmitter Programming . The transmitter should program.
    • If the transmitter does not program, test the keyless entry coax and/or antenna for a short to ground or an open/high resistance. If the circuit tests normal, replace the RCDLR.
