Diagram shows there is a 10 amp fuse. So check fuses in the engine and cabin area. A quick way to check there is power is by connecting a scan tool and do an OBD2 read out. If your scanner powers on then fuse is good. If your scanner communicates then the problem will be with the sh0ops machine.

If you have no communications with the power control module, disconnect the battery cables and touch both leads and leave them touching for five to ten minutes. Reconnect scanner and check it communicates. If it is good then drive vehicle for twenty minutes on freeway for twenty to thirty minutes at fifty five mph no A/C and try not to use the brake pedal at all or as little as possible.

Check I/M results. Most states should let you pass with the evap monitor pending. If all others are complete then you should be ready to pass the computer check of the inspection.
