B1A24-00-KEY NOT PROGRAMMED

For a complete wiring diagram, refer to the Wiring Information.

Theory of Operation

Whenever a Fob-Integrated-Key (FOBIK) is inserted in the Ignition Node Module (IGNM), the Radio Frequency Hub (RF-Hub) performs a self test and resynchronization routine. During the routine, the RF-Hub interrogates the FOBIK, performing various validity and performance tests. The repair of this fault condition relies on the programmed status of the FOBIK.

- When Monitored:
During interrogation, the FOBIK sends a low frequency (LF) signal to the RF-Hub that includes the FOBIK identification information.

- Set Conditions:
This DTC sets if the RF-Hub receives the default, secret key status from a FOBIK. Once set, this DTC will remain active until a valid, programmed FOBIK is inserted in the IGNM and rotated through the ON position.





Diagnostic Test
PROGRAM ALL FOBiK's
1. NOTE: All FOBIKs that are to be used in this vehicle must remain on the front seat near the console during programming.

2. With the scan tool, select "Misc. Functions", "Program Ignition FOBIKs" and follow the instructions on the screen.
3. Program all FOBIKs that are used with this vehicle.
4. Try each FOBIK that was programmed.

Do all FOBIKs operate properly?

Yes

- Test complete.

No

- With the scan tool perform the "RFH", "Reset ECU" and repeat this test from the beginning.
