GaragePro coverage for GMC
We hold 16 control units against GMC at make level, which means they apply to every GMC in the lists below. A further 6 special functions are recorded for the make, and those are on Advanced only.
Coverage is recorded per make. One GMC model additionally has rows of its own, and those are added to the make-level set for it rather than used in place of it. Run the check with your model and year for the exact list.
Models with their own coverage rows
One GMC model has rows recorded against it specifically. The counts are the make-level set with that model’s own rows merged in, which is exactly what the compatibility check returns for it.
| Model | Control units | Special functions |
|---|---|---|
| Sierra | 16 | 7 |
A model in this table is not better covered than one that is not — it means someone has connected to that GMC and recorded what answered. Everything else runs on the make-level record below.

Availability is per vehicle, not per make What your car exposes depends on its trim and model year — a variant with a cable handbrake has no electronic parking brake to retract. Run the check with your model and year for the list that applies to your vehicle.
Which plan for a GMC?
Coverage is identical on all of them. Every plan reads and clears the same control units on the same vehicle; what changes is how many vehicles you can add and whether the special functions are included.

This page is the make-level record. The check returns the unit list and function count for your model and year, which is the number that matters when you are choosing between plans.

All make pagesQuestions about this coverage
Will it read the airbag light?
If SRS or Airbag is in the control-unit list on this page, yes — it is read and faults on it clear, on every plan. The list above is the whole answer; nothing is held back for a higher plan.
Which plan do I need for a service reset?
Advanced. A service reset is a special function, and the special functions are Advanced-only regardless of make. Reading and clearing faults on every control unit is on every plan.
My model is not in the table above.
Then it runs on the make-level record, which is the list of control units at the top of this page. The table only names the models we have recorded rows against individually — it is not a list of what is supported.
Do I need a connector cable?
Cars use the standard 16-pin OBD-II port and need nothing extra. The extension cable is only for a port tucked behind trim where the scanner will not sit. Bikes are the exception — those need a make-specific cable, and it is on the bike product.
