Autel MaxiSys Missing Vehicle-Specific Service Functions (Parking Brake Retraction and Others)
Some newer vehicles require a specific service function - like parking brake retraction - that a given Autel MaxiSys tool or software version may not yet support.
Autel MaxiSys Function Coverage Overview
Autel MaxiSys tools cover a wide range of vehicle service functions, but coverage for a specific function on a specific model isn't guaranteed just because the tool otherwise supports that brand. A confirmed case: a MaxiSys MS909 could not perform the parking brake retraction function needed for rear brake service on a 2025 VW Jetta, even though the tool worked for other VW functions.
Why This Happens
Vehicle-specific service functions are added to Autel software over time, and newer model years can outpace what a given tool or software version supports. A tool that handles most of a brand's lineup can still be missing a specific function on the newest models.
Before Quoting a Job Requiring a Specific Function
If a job depends on a specific service function - such as parking brake retraction for rear brake work - confirm your Autel tool supports that exact function on that exact model year before quoting the job. Don't assume general brand compatibility covers every function on every model.
If Your Autel Tool Is Missing a Function You Need
Contact Autel support directly at 855-288-3587 to confirm whether the function is supported, and if not, when it's expected. AE Tools can also help submit a support ticket if you're unsure how to proceed.
