B1A24-KEY NOT PROGRAMMED

For a complete wiring diagram REFER to DIAGRAMS/ELECTRICAL .

Theory of Operation


Whenever a Fobik is inserted in the Wireless Ignition Node (WIN) base station, the WIN performs a self test and resynchronization routine. During the routine, the WIN 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 resynchronization, the fobik sends an RF signal to the WIN that includes the fobik programmed status.

- Set Condition:
This DTC sets if the WIN receives the default, blank key status from a fobik. Once set, this DTC will remain active until a valid, programmed fobik is inserted in the base station and rotated through the ON position.







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. VERIFY THE WIRELESS IGNITION NODE (WIN) HAS BEEN PROPERLY INITIALIZED

NOTE: When diagnosing any Theft or Security system concern, all fobiks must be present

With the scan tool, read the Number of Key/Fobs Programmed under Data Display.
Does the scan tool show 2 or more Key/Fobs Programmed?

Yes


- Go To 3


No


- Using the scan tool, program 2 fobiks.Perform the THEFT AND SECURITY SYSTEMS VERIFICATION TEST.Theft and Security System Verification Test


3. CHECK OPERATION OF THE FOBIK IN USE

NOTE: Verify the fobik in use is the fobik causing the DTC to set.

Replace the fobik currently in use.
Using the scan tool, program a new fobik to the WIN.
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.
