Jeep Wagoneer S • PROXI (proxy) alignment

Jeep Wagoneer S PROXI Alignment (Proxy Alignment)

A model-focused guide for workshops working on Jeep Wagoneer S. “PROXI alignment” is often used as a shorthand for two things: the vehicle configuration map and the synchronization routine that makes modules agree on that map. FCA PROXI Tool is built for the configuration side: load an exported buffer, make precise byte/bit edits, and save an output file with consistent CRC/checksums for a clean write-back workflow.

Common triggers

When Wagoneer S projects hit “alignment” topics

  • Retrofits (infotainment, cluster, cameras/ADAS options) where the car detects a configuration mismatch.
  • Module replacement (BCM/cluster/radio) followed by “not configured / not aligned” states.
  • Market/region coding work (US ↔ EU logic changes) that requires configuration edits.
Common symptoms

What owners and shops search for

  • Cluster mismatch indicators (often described as “configuration mismatch” behavior; some owners report it as a blinking odometer on certain Jeep platforms).
  • “proxy alignment” / “proxi alignment” seen in scan tool menus or DTC descriptions.
  • Multiple modules complaining about “configuration not programmed / not aligned”.
Reality check

SGW / access on newer Stellantis builds

On newer Stellantis platforms, write access can depend on authorized diagnostic access (SGW/AutoAuth). If your adapter or workflow cannot complete a write/sync step, you may need an authorized route (dealer or approved access).
How FCA PROXI Tool fits

Configuration-first workflow

  • Read/export the original configuration buffer and store an untouched backup.
  • Edit bytes/bits with Standard / Advanced / PROXI Map Editor.
  • Save a checksum-correct output file (CRC/checksums recalculated).
  • Write back using your preferred workflow (PassThru / diagnostic tool / shop workflow).

Quick navigation

What “PROXI alignment” means on Wagoneer S

Think of “alignment” as the vehicle agreeing on a single configuration truth. On a brand-new platform, scan tools may label this differently, but the underlying goal is the same: configuration consistency. People often use the term for both the configuration data and the synchronization step. Your job is to identify which one is actually missing in the current situation.

Note: Wagoneer S is a very new platform. Some tools may not explicitly show a “PROXI alignment” menu item yet. In that case, focus on exporting the configuration buffer, making checksum-correct edits, and writing only to the ECUs you intend to change.
Definition

Configuration map vs alignment routine

The configuration map defines equipment and behavior (options, region settings, logic flags). The alignment routine is the distribution/sync step that makes modules accept the currently approved map.
Goal

Minimize mismatch states

When you preserve configuration integrity (only change what is required and keep checksums correct), the vehicle is less likely to fall into mismatch behavior after flashing or retrofits.
Keyword

“Proxy” vs “PROXI”

Most people type “proxy alignment”. FCA terminology typically uses PROXI alignment. Use both terms for search, but keep the meaning consistent.

Recommended workshop workflow (Wagoneer S)

A conservative workflow that protects the original configuration and reduces the risk of creating a mismatch state.

  • Stable power: keep the vehicle on a proper supply during reads/writes.
  • Backup first: save the original exported configuration buffer unchanged.
  • Edit with intent: change only the bytes/bits required for your project (retrofit/region/behavior).
  • Checksum-correct output: save an output file with recalculated CRC/checksums.
  • Write back: use your preferred diagnostic workflow to write the file to the target module.

When you may need an alignment routine (and when you don’t)

FCA PROXI Tool focuses on configuration editing + checksum-correct output and supports writing to selected ECUs. When you preserve the original Configuration Code, most retrofit/conversion edits stay consistent without a full network sync. An explicit alignment routine is mainly needed when the vehicle’s configuration identity changed or a major module swap forces re-synchronization.

Identity changed

Configuration Code was altered

If the configuration identity is changed (or imported from another vehicle), modules can disagree. In that case, a scan-tool sync routine may be required to re-establish one accepted identity.
Major module swap

Key module replaced with different identity

Replacing BCM/cluster/infotainment can introduce a different identity or approved map. Use a sync routine only when the network cannot agree after you correct and write the configuration.
Already mismatching

Mismatch symptoms persist from an identity issue

Blinking odometer / mismatch DTCs can be a symptom of identity disagreement. Fix the configuration cause first. Use a sync routine only if the vehicle still insists after a checksum-correct write.

FAQ

Does a blinking odometer always mean I need PROXI alignment?
Not always. It usually indicates a configuration mismatch. Start by verifying what changed (retrofit, module replacement, region coding) and ensure the configuration you write back is checksum-correct.
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.
Will I always need SGW/AutoAuth access on Wagoneer?
Not always, but write/sync access on newer Stellantis vehicles can be restricted depending on model year, region, and operation. If your workflow cannot complete the write/sync, authorized access may be required.
What should I provide for configuration editing help?
At minimum: vehicle details (year/model), the original exported configuration buffer, and a clear goal (retrofit, region change, behavior). Always keep a clean untouched backup of the original file.
