Service park assist fuse location 2019 GMC Sierra

[Welder2014]

Replaced damaged rear park sensor but still get service park assist message. The switch on dash will not light amber. Does any body know the fuse location for the park assist module. Did go over the manual and online but cant find fuse location. Thanks.

Guess not. Thanks anyway.

You

a) probably need to look at the wiring diagrams to know what fuses are used for it

b) get/use a more advanced code reader, that can get codes from all the system in yourur truck, to find what problem the truck has noticed to turn on that message

Fuses are labeled in the fuse box lids.

Did go over the labels on fuse box lids did not find the parking aid fuses. Guess the module is shared with something else that is labeled. Will need to do what Davester posted buy an advanced code reader and see what the problem is. Now start the search for a code reader. Thanks.

And yet, I was still able to help the o.p. more than you did.
