B1A26-MAXIMUM NUMBER OF KEYS PROGRAMMED

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

Theory of Operation

The Wireless Ignition Node (WIN) is preprogrammed from the factory with 2 Fob-Integrated-Keys (Fobik's), with the capability to have a maximum of 8 Fobik's programmed in total. Additional programmed Fobik's are automatically learned to the next available FOBIK position in the WIN software and do not overwrite any previous positions. The repair of this fault condition relies on the current number of Fobik's programmed into the WIN and the number of available positions in the WIN software.

- When Monitored:
When the WIN is placed into FOBIK programming mode, the module references the number of unique FOBIK identifications stored in its memory.

- Set Condition:
In the event the WIN detects the user is attempting to program a 9th FOBIK, this DTC will be set as active.





Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Wireless Ignition Node (WIN) Pre-Diagnostic Procedure.

1. DETERMINE ACTIVE OR STORED DTC

Is the DTC active or stored?

WIN - ACTIVE DTC

- Go To 2

WIN - STORED DTC

- Perform the WIRELESS IGNITION NODE (WIN) INTERMITTENT TEST. Wireless Ignition Node (WIN) Intermittent Condition Test.

2. CLEAR Fobik's PROGRAMMED INTO WIRELESS IGNITION NODE (WIN) AND REPROGRAM Fobik's

NOTE: The below procedure clears all Fobik's currently programmed in the WIN software. It is important to obtain all the customer Fobik's so they may be reprogrammed to the module. Any Fobik's not present for the following procedure will be inoperable and require additional programming to function.

1. Using the scan tool, use the Erase All Ignition Keys feature under Miscellaneous Functions.
2. Using the scan tool, use the Program Ignition Keys or Key Fobs feature under Miscellaneous Functions.
3. Program all the customer key(s) into the WIN (up to eight).
4. Use the scan tool and erase all DTCs in the WIN.
5. Turn the Ignition Off, and wait 15 seconds before turning the Ignition On.
6. Wait one minute, and read active DTCs.

Does the scan tool display: B1A26-MAXIMUM NUMBER OF KEYS PROGRAMMED?

Yes

- Replace and program the Wireless Ignition Node (WIN). Wireless Ignition Node Receiver - Removal.
- Perform the WIN VERIFICATION TEST. Wireless Ignition Node (WIN) Verification Test.

No

- Repair is complete.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
