Circuit/System Verification

WARNING: This page is about a different car, the 2010 Pontiac G5 and 2010 Chevrolet Cobalt. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: The diagnostic assumes the transmitter worked with the vehicle at one time.
  1. Place the transmitter on the J 43241  test pad 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 do not function, replace the transmitter battery and retest with the J 43241  . See Special Tools . If the condition continues after battery replacement, replace the transmitter.
  2. Operate the transmitter function while observing the vehicle. The vehicle should perform each of the corresponding functions selected on the transmitter.
    • If any function does not work, program the keyless entry transmitter, refer to Remote Control Door Lock Transmitter Programming . If any function still does not work after reprogramming, replace the transmitter. If any function still does not work after replacing the transmitter, replace the RCDLR.
