2023-2025 Tonale / Hornet Remote Start Parking Lamp Issue

Owners of 2023-2025 Alfa Romeo Tonale and Dodge Hornet vehicles may experience an issue where the parking lamps fail to illuminate when the vehicle is started remotely. This condition, detailed in Stellantis Technical Service Bulletin S2508000047, specifically affects the vehicle's electrical system related to remote start functionality, leading to the symptom of Tonale Hornet remote start parking lamps not illuminating.

This bulletin, released in June 2025, provides a straightforward solution for this specific symptom, ensuring proper vehicle operation and visibility during remote start sequences. The STAR Online Publication S2508000047 outlines steps for technicians and owners to address this without complex diagnostics.

Symptoms

The primary symptom observed by owners is that the "Parking Lamps do Not Illuminate When the Vehicle is Remotely Started". This means that while other remote start functions may operate correctly, the exterior parking lights, which typically provide visibility and confirm the vehicle's status, remain off. This issue is consistent across affected 2023-2025 Alfa Romeo Tonale and Dodge Hornet models.

Fault Codes / DTCs

Importantly, this specific issue does not trigger any Diagnostic Trouble Codes (DTCs). Technicians observing the symptom will find that no modules have set any DTCs, indicating that the problem is not a system fault but rather a configuration or communication anomaly that prevents the parking lamps from activating as expected during a remote start command.

Diagnosis / Trigger Conditions

Diagnosis for this condition is relatively simple. The parking lamps are expected to function normally during all other operations, such as when the vehicle is manually started or when the lights are turned on via the control stalk. The problem is isolated to the remote start sequence. If the lamps work correctly in all other scenarios and no DTCs are present, the issue aligns with the conditions described in TSB S2508000047. This confirms the Tonale Hornet remote start parking lamps issue is likely a setting rather than a hardware failure.

Repair Procedure Summary

The repair for this issue involves a simple adjustment within the vehicle's infotainment system. The steps are as follows:

1. Access the Radio Menu: Enter the radio or infotainment system's main menu. This is the central hub for vehicle settings.
2. Navigate to Lights Settings: Locate and select the 'Lights' settings option within the menu. The provided image shows this option clearly visible under the 'Vehicle' section of the settings.
3. Verify 'Flash Lamps With Lock' Setting: Ensure that the "Flash Lamps With Lock" setting is selected (turned on). This setting, as depicted in the infotainment screen image, controls the behavior of the exterior lights in certain scenarios.
4. Toggle the Setting: Even if the "Flash Lamps With Lock" setting appears to be already 'on', it is crucial to toggle it. This means turning the setting off and then immediately turning it back on. This action helps to re-register the setting within the vehicle's electronic control modules.
5. Allow Full BUS Sleep Cycle: After toggling the setting, the vehicle must be allowed to enter a full BUS sleep cycle. This typically involves turning off the vehicle, exiting, and letting it sit undisturbed for a period. This allows all electronic modules to power down completely and accept the changes made to the setting.

Once these steps are completed, the setting should be accepted, and the parking lamps should illuminate as expected during a remote start command.
