## NHTSA's summary

Instrument Cluster Update: Certain Cummins equipped vehicles with alternators capable of producing in excess of 160 amps, the truck voltage may increase immediately after the Cummins grid heater cycles off, causing the ICU3S display to reset \(looks like the reset that occurs during ignition key on\). After reset, the ICU will resume normal function.
