  1. Place the transmitter on the test pad of the J 43241  and press each transmitter button one at a time, holding each button for three seconds. The tester should sound a tone and illuminate a green light for the entire three second button press.
    • If one or more buttons does not sound the tone and illuminate the green light for the entire three seconds, replace the transmitter battery and retest with the J 43241 . If the condition continues after battery replacement, replace the transmitter.
  2. Program the transmitter. Refer to Remote Control Door Lock Transmitter Programming . The transmitter should successfully complete the programming procedure.
    • If the transmitter does not program, replace the keyless entry transmitter. If the new keyless entry transmitter does not complete the programming, replace the RCDLR.
  3. Operate the transmitter function while observing the vehicle. The vehicle should perform each of the corresponding functions when selected on the transmitter.
    • If any of the vehicle functions are inoperative, replace the keyless entry transmitter. If the functions remain inoperative after replacement of the transmitter, replace the RCDLR.
