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. The tester should sound a tone and illuminate a green light with each button press.
- 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 . If the condition continues after battery replacement, replace the transmitter.
- Inspect the external RF antenna connection at the RCDLR. First, gently pull on the coax connector at the module. If the coax comes out, then it was not seated properly. Remove and carefully inspect the coax connection for bent blades or a bent center pin. Fix coax connection if necessary and re-seat connector until a "click" is heard. Gently pull on the coax connection to make sure it is seated properly.
- 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 and Theft Deterrent Transmitter Programming (North America, except Canada) , Remote Control Door Lock and Theft Deterrent Transmitter Programming (Canada, Europe, Asia, Middle East) . The transmitter should program.
- If the transmitter does not program, test the keyless entry antenna for an open/high resistance. If the circuit tests normal, replace the RCDLR.
