Circuit/System Testing
- Verify that the transmitter is the correct transmitter for the vehicle.
- If not the correct transmitter, replace the transmitter.
- Verify the scan tool FOB Programmed parameter for the appropriate transmitter is Yes.
- 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.
- 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.
- 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.
- If all circuits test normal, replace the RCDLR.
