Alfa Romeo Tonale • PROXI (proxy) alignment

Alfa Romeo Tonale PROXI Alignment (Proxy Alignment)

A practical page for workshops working on Alfa Romeo Tonale. People often search “proxy alignment” when a vehicle shows configuration mismatch behavior after retrofits or module replacement. FCA PROXI Tool focuses on the configuration itself: load the exported buffer, edit bytes/bits, and save an output file with consistent CRC/checksums so your write-back step stays technically correct. In FCA PROXI Tool workflows, we preserve the original Configuration Code and recalculate CRC/checksums so the vehicle accepts the edited buffer without triggering a mismatch state in typical retrofit/conversion edits.

Common triggers

When Tonale projects hit alignment issues

  • Retrofits where the car detects a mismatch (options/features changed).
  • Module replacement followed by “not configured / not aligned” states.
  • Market/region coding or behavior changes that require configuration edits.
Common symptoms

What people search for

  • “proxy alignment” / “proxi alignment” in scan tool menus.
  • Multiple modules reporting configuration mismatch.
  • After-coding issues where features behave incorrectly until modules agree.
Platform note

Tonale and Dodge Hornet overlap

Tonale and Dodge Hornet are frequently serviced with similar diagnostic patterns. If you work on both, documentation and symptom keywords often overlap, so keep “Tonale / Hornet” terms in your notes and search.
How FCA PROXI Tool fits

Configuration-first workflow

  • Read/export the original configuration buffer and keep an untouched backup.
  • Edit bytes/bits with Standard / Advanced / PROXI Map Editor.
  • Save a checksum-correct output file (CRC/checksums recalculated).
  • Write back via your workshop workflow and run a sync routine only if required.

Quick navigation

What “PROXI alignment” means on Tonale

The term gets used as a catch-all for “configuration mismatch”. Split it into two parts: the configuration data and the sync step that makes all modules accept the same map.

Definition

Configuration map vs alignment routine

The configuration map defines installed equipment and logic flags. The alignment routine is the sync/distribution step that forces agreement across modules.
Goal

Keep edits minimal and checksum-correct

Most problems come from mismatched expectations between modules. Editing only what you must and keeping checksums correct reduces mismatch risk after a write.
Keyword

“Proxy” vs “PROXI”

Search traffic often says “proxy alignment”. FCA terminology uses PROXI alignment. Use both words on the page so users find it.

Recommended workflow (Tonale)

A conservative approach for configuration changes and retrofit work.

  • Backup: save the original exported configuration buffer unchanged.
  • Edit with intent: change only required bytes/bits, document your changes.
  • Save correct output: ensure CRC/checksums are recalculated.
  • Write back: complete the write using your shop workflow.
  • Sync if required: run an alignment/sync step only if the platform insists after a correct write.

Common failure modes (what usually goes wrong)

Most “alignment failed” reports fall into one of these categories. Diagnose the cause before re-trying the same write.

Mismatch

Configuration changed but modules disagree

If one module accepts a configuration that another rejects, you will see mismatch symptoms. Verify your intended change and keep edits minimal.
Access

Write blocked / restricted

On newer vehicles, writes and sync steps may be restricted. If your tool cannot complete the operation, an authorized workflow may be required.
Inputs

No clean baseline

If you do not have the untouched original buffer, it becomes harder to isolate what change caused the mismatch. Always start by backing up before edits.

FAQ

Does this Tonale guide also apply to Dodge Hornet?
Often, yes. Many diagnostic patterns and user search terms overlap between Tonale and Hornet. Still, always validate the exact model year and configuration before making changes.
Is “proxy alignment” the same as PROXI alignment?
Yes. “Proxy alignment” is a common search term, while FCA documentation typically uses the term PROXI alignment.
What do you need for configuration editing work?
A clean backup of the original configuration buffer plus vehicle details and a clear target change (retrofit/region/behavior). Keep the original file untouched.
Why do some operations fail even with a correct file?
Some write or sync steps can be restricted on newer platforms depending on the module and access level. If your workflow cannot complete the operation, authorized access may be required.
