DTC Descriptor
DTC B3105: Keyless Entry System Key Fobs Not ProgrammedCircuit/System Description
The remote control door lock receiver (RCDLR) monitors the number of keyless entry transmitters programmed. Until at least one transmitter is programmed, the RCDLR determines a malfunction condition exists.
Conditions for Running the DTC
The keyless entry system must be enabled and a test is ran every time the key is cycled.
Conditions for Setting the DTC
The DTC is set if there are no keyless entry transmitter programmed to the RCDLR.
Action Taken When the DTC Sets
The keyless entry system is inoperative.
Conditions for Clearing the DTC
A current DTC is cleared at least one transmitter has been programmed to the RCDLR.

Circuit/System Verification
Attempt to program the transmitter, refer to Transmitter Programming . Transmitter should program.
Circuit/System Testing
- Verify that the transmitter is the correct transmitter for the vehicle.
- Place the transmitter on the test pad of the J 43241 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.
- Attempt to program the transmitter, refer to Transmitter Programming . The transmitter should program.
| ⇒ | If not correct, replace the transmitter. |
| ⇒ | 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. |
| ⇒ | If the transmitter does not program, test the keyless entry antenna for an open/high resistance. If the circuit tests normal, replace the RCDLR. |
Repair Instructions
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
