Circuit/System Testing

WARNING: This page is about a different variant/trim than selected.
  1. Verify that the transmitter is the correct transmitter for the vehicle.
    • If not correct, replace the transmitter.
  2. Place the transmitter on the test pad of the J 43241  keyless entry tester and press each button of the transmitter one at a time. 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  keyless entry tester. If the condition continues after battery replacement, replace the transmitter.
  3. Attempt to program the transmitter, refer to Remote Control Door Lock Transmitter Learn (without ATH) , (without ATH) or Remote Control Door Lock and Theft Deterrent Transmitter Programming (with ATH - N America and Asia) , Remote Control Door Lock and Theft Deterrent Transmitter Programming (with ATH - Canada and Europe)  (with ATH). The transmitter should program.
    • If the transmitter does not program, replace the RCDLR.
