Service bulletin MI1423

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

A new software version (v1.06) is available to update the CANtrak (Tire Pressure Monitoring System) module. This new version will allows a 10 min. delay before the ?SYSTEM ERROR NOT ALL TIRES MONITORED? message appears in the vehicle cluster when a tire pressure sensor loses its connection. NOTE: The new software version will only delays the cluster message, the CANtrak screen will still displays a ??? code for the corresponding pressure sensor.
