B1A26-MAXIMUM NUMBER OF KEYS PROGRAMMED

For a complete wiring diagram REFER to DIAGRAMS/ELECTRICAL .

Theory of Operation


The Wireless Ignition Node (WIN) is preprogrammed from the factory with 2 fobiks, with the capability to have a maximum of 8 fobiks programmed in total. Additional programmed fobiks are automatically learned to the next available fobik position in the Wireless Ignition Node (WIN) software and do not overwrite any previous positions. The repair of this fault condition relies on the current number of fobiks 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.Initial Inspection and Diagnostic Overview


Diagnostic Test


1. DETERMINE ACTIVE OR STORED DTC
Is the DTC active or stored?

WIN - ACTIVE DTC


- Go To 2


WIN - STORED DTC


- Perform the THEFT AND SECURITY SYSTEMS INTERMITTENT TEST.Symptom Related Diagnostic Procedures


2. CLEAR FOBIKS PROGRAMMED INTO WIRELESS IGNITION NODE (WIN) AND REPROGRAM FOBIKS
NOTE: The below procedure clears all fobiks currently programmed in the WIN software. It is important to obtain all the customer fobiks so they may be reprogrammed to the module. Any fobiks not present for the following procedure will be inoperable and require additional programming to function.

With the scan tool, use the Erase All Ignition Keys feature under Miscellaneous Functions.
With the scan tool, use the Program Ignition Keys or Key Fobs feature under Miscellaneous Functions.
Program all the customer key(s) into the WIN (up to eight)
Use the scan tool and erase all codes in the WIN.
Turn the Ignition Off, and wait 15 seconds before turning the Ignition On.
Wait one minute, and read active codes.
Does the scan tool display this DTC as active?

Yes

NOTE: Technicians must use the scan tool to perform the WIN Programming procedure after a module replacement.
Replace the Wireless Ignition Node.
