2023-2024 Dodge Hornet Instrument Cluster: Blank Screens, TSBs, and Replacement Programming
This guide covers common failures, software updates, and the critical programming steps required when replacing the digital instrument cluster in your Dodge Hornet.
- Many instrument cluster issues like blank screens or random warnings are software glitches that can be fixed with a dealer-installed update (TSB).
- A replacement cluster is NOT plug-and-play; it requires a dealer or specialist to perform a "Proxi Alignment" to sync it with the vehicle.
- A flashing odometer is a clear sign of a Proxi Alignment problem, meaning the modules are not communicating correctly.
- When buying a used cluster, you must match the part number and options (like Traffic Sign Information) and have the mileage professionally corrected.
Known Issues, Recalls, and Technical Service Bulletins (TSBs)
As a relatively new vehicle, the 2023-2024 Dodge Hornet has several known issues that are primarily software-related and addressed by dealer-installed updates rather than physical part replacement. Owners have reported issues including blacked-out digital instrument clusters and numerous warning lights appearing.
Recalls
While there are several recalls for the Hornet, none directly target the instrument cluster for replacement. However, related electronic issues are addressed:
- NHTSA Campaign Number 23V733 (Incorrect Placard Weight): This recall is for an incorrect label, but it highlights the level of electronic integration and the need for correct vehicle data.
- Pedestrian Alert Siren (PHEV models): A recall was issued because the pedestrian alert siren may be missing or disconnected, a system whose status would be monitored by the vehicle's electronic modules.
Technical Service Bulletins (TSBs)
More relevant to cluster issues are the TSBs, which are instructions for dealers to fix common problems. Many early-build Hornets have software glitches that can mimic a hardware failure.
- TSB 08-119-23 / RSU 23-128: This bulletin addresses customer complaints of message pop-ups and frequent warning lights related to the front camera, or temporary camera blindness. The fix is to reprogram the Instrument Panel Cluster (IPC) with updated software. This applies to vehicles built on or before February 4, 2023.
- TSB S2308000036: This addresses a condition where the cluster displays an Electric Power Steering (EPS) fault warning lamp. This is also often a software-related issue that requires dealer diagnosis.
Pro Tip: Before assuming your instrument cluster has failed and needs replacement, check with a Dodge dealer to see if any software updates or TSBs apply to your vehicle's VIN. Many intermittent electronic issues on the Hornet are resolved with a simple software reflash.
Symptoms of a Failing Instrument Cluster
While many issues are software-based, the instrument cluster can still fail physically. Symptoms of a true hardware failure include:
- Completely Blank or Black Screen: The screen does not turn on at all, even after attempting a reset procedure.
- Gauges Not Working or Inaccurate: The digital representations of the speedometer, tachometer, or other gauges are frozen, incorrect, or absent.
- Persistent Warning Lights: Multiple warning lights stay on even after confirming there are no actual faults with those systems.
- Flickering or Distorted Display: The screen flickers, shows garbled text, or has dead pixels or lines across the display.
- Communication-Related OBD-II Codes: A common trouble code associated with a failing cluster is U0155 (Lost Communication with Instrument Panel Control Module), which indicates other modules on the vehicle can no longer receive a signal from the cluster.
Buying a Used 2023-2024 Dodge Hornet Instrument Cluster
Given the high cost of a new OEM cluster, a used unit is a viable option, but it comes with critical considerations. This is not a simple part to swap.
Verify Compatibility: Part Numbers and Options
It is absolutely essential to match the part number exactly. The initial data specifies part numbers 68615386AA and 68647335AA. Furthermore, you must ensure the donor vehicle had the same options as yours. The most critical one noted is the Traffic Sign Information feature (option code SJF). A cluster from a vehicle without this feature will not work correctly in a vehicle that has it, and vice-versa. Always provide your vehicle's VIN to the seller to confirm compatibility.
Warning: The mileage displayed on the used cluster will be from the donor vehicle. This will create a mileage discrepancy on your vehicle's record. It is often illegal to sell a vehicle with an inaccurate odometer reading. The mileage must be corrected by a professional during programming.
Physical Inspection
When purchasing a used cluster, inspect it for:
- Screen Condition: Look for deep scratches, cracks, or any signs of delamination.
- Connectors: Ensure the electrical connectors on the back are clean, dry, and have no bent or broken pins.
- Housing: Check for cracks or broken mounting tabs on the plastic housing.
Programming and Calibration: This is NOT Plug-and-Play
You cannot simply swap a used instrument cluster into your Dodge Hornet and expect it to work. The replacement module must be programmed to the vehicle.
- Secure Gateway (SGW): Like all modern Stellantis vehicles, the Hornet is equipped with a Secure Gateway module that prevents unauthorized access to the vehicle's network. This requires a dealer's WiTech scan tool or a licensed aftermarket tool with a valid subscription to perform any programming.
- Proxi Alignment: This is a Stellantis-specific procedure that synchronizes the configuration data of all electronic modules on the vehicle. When a new module like an instrument cluster is installed, a Proxi Alignment must be performed to make the Body Control Module (BCM) and other ECUs recognize it. Failure to do this will result in a flashing odometer and numerous error codes.
- Mileage and VIN Programming: The cluster must be programmed with your vehicle's correct VIN and the actual mileage must be set. This is a specialized task that typically requires a dealership or a qualified automotive electronics specialist.

Frequently Asked Questions (FAQ)
Can I install the cluster myself and drive to the dealer for programming?
Yes, the physical replacement is straightforward for a DIY mechanic. However, the vehicle may not be safe or legal to drive if the speedometer is not functioning. The odometer will likely flash, and multiple warning lights may be present. It is best to have the vehicle towed or arrange for a mobile technician who can perform the Proxi alignment on-site.
What is a Proxi Alignment?
Proxi Alignment is a procedure that synchronizes the settings of all electronic control modules in a Stellantis (Dodge, Chrysler, Jeep, Fiat) vehicle. The Body Control Module (BCM) holds the master configuration list, and the alignment process ensures every module, including the new instrument cluster, agrees on the vehicle's features and options. Without this, the system will detect a mismatch, leading to a flashing odometer and other errors.
My screen is blank. How can I try to reset it myself?
Some owners have had success with a soft reset procedure. Turn the vehicle off and wait 30 seconds. Then, without pressing the brake pedal, push the start button to enter accessory mode. If the screen is still blank, press the accelerator pedal fully and slowly three times within 10 seconds. This can sometimes force the cluster to reset. If this fails, a dealer visit is necessary.
Will a cluster from an Alfa Romeo Tonale work in my Dodge Hornet?
While the Dodge Hornet and Alfa Romeo Tonale are built on the same platform and share many parts, using a cluster from a Tonale is not recommended. The programming, branding (logos), and specific feature sets are different. You should only use a cluster with a part number designated for the Dodge Hornet to ensure full functionality.
