WARNING: This page is about a different car, the 2008 Buick LaCrosse and 2008 Buick Allure. However, it is still accessible from the selected car via links, so may be relevant.
  1. Verify that the transmitter is the correct transmitter for the vehicle.
    • If not the correct transmitter, replace the transmitter.
  2. Place the transmitter on the test pad of the J 43241  and press each button of the transmitter one at a time. See Special Tools . The tester should sound a tone and illuminate a green light when each button is pressed.
    • 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.
  3. 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, program the transmitter and retest. Refer to Transmitter Programming . If the condition continues after transmitter programming, replace the transmitter.
  4. If all circuits test normal, replace the RCDLR.
