DTC U2016-51: Control Module Main Software - Not programmed: Action

NOTE: Do not try to solely change the module fitted to the bladder hose as it is calibrated as an integral assembly with the seat cushion foam

Using the manufacturer approved diagnostic system, re-configure the occupant classification sensor control module with the latest level software
If fault persists, check and install a new occupant classification sensor service kit as required (complete service kit consists of foam, occupant classification sensor bladder mat with attached smart digital pressure sensor)
