There are a number of sensors for your convertible top !
DTC B1010 08: System Sensors Data Mismatch signal invalid
DTC B1010 08 sets when the folding top control (FTC) module detects a switch is not in the proper state when compared to other switches. The conditions that cause DTC B1010 08 to set may also set other Folding Top DTCs. The position and direction of the folding top when the fault occurs will determine whether DTC B1010 08 will set or another Folding Top DTC will set. If any Folding Top DTCs between DTC B1296-DTC B3685 are set, diagnose those DTCs first. After diagnosing any other Folding Top DTCs, clear DTCs and operate the Folding Top to see if DTC B1010 08 resets before diagnosing it.
DTC B1296 01: Movable Roof Header Unlatched Sensor Circuit short to battery
DTC B1296 06: Movable Roof Header Unlatched Sensor Circuit short to ground or open
DTC B1296 58: Movable Roof Header Unlatched Sensor Circuit incorrect reaction after event

You best bet is to take your vehicle to a ASE certified repair shop or to a GM dealer .
