Alarm Module: Testing and Inspection






Wireless Ignition Node (WIN)

For proper diagnosis and testing of the Wireless Ignition Node (WIN), Remote Keyless Entry (RKE) System, and the Tire Pressure Monitoring (TPM), use a scan tool and appropriate diagnostic information.

NOTE: After a WIN is replaced, the FOB with integrated keys (FOBIKs) need to be programmed to the new WIN. Follow the directions on the diagnostic scan tool.
