Code B133B 2017 Chevrolet Silverado Description

The Human Machine Interface Control Module receives a signal from the Human Machine Interface Control Module Bypass Module indicating reverse gear status. The reverse gear status is used to determine when to activate the rearview camera display. The Human Machine Interface Control Module also receives another reverse gear status message via serial data. The Human Machine Interface Control Module compares the two serial data messages to verify the plausibility of the messages. The Diagnostic Trouble Code (DTC) will be set when the Human Machine Interface Control Module has determined the reverse message states do not match and are therefore not plausible.
