2024 Alfa Romeo Tonale PCM Software Update for MIL and DTCs

Alfa Romeo has issued Technical Service Bulletin (TSB) 18-054-24 REV. A to address specific issues affecting the 2024 Alfa Romeo Tonale. This bulletin focuses on resolving instances where the Malfunction Indicator Lamp (MIL) illuminates and certain diagnostic trouble codes (DTCs) are set. The primary solution involves a 2024 Alfa Romeo Tonale PCM software update.

This TSB supersedes TSB 18-038-24 REV. A, dated November 09, 2024. All revisions are highlighted with asterisks in the original document and include an updated build date, new labor operations, and a revised repair procedure. This bulletin has also been released as Rapid Service Update (RSU) 24-169, ensuring applicable VINs are loaded for service.

Symptoms

Owners of affected vehicles may experience the Malfunction Indicator Lamp (MIL) illuminating on the dashboard. This warning light indicates a detected issue within the vehicle's systems. Along with the MIL illumination, specific diagnostic trouble codes (DTCs) will be stored in the vehicle's computer system.

Fault Codes / DTCs

When the MIL illuminates, technicians will find one or both of the following Diagnostic Trouble Codes (DTCs) stored in the vehicle's system:

Code	Description
P2601-00	Electric Coolant Pump Control Circuit Performance Stuck Off
P219A	Bank 1 Air-Fuel Ratio Imbalance

These codes point to a software-related issue within the Powertrain Control Module (PCM).

Diagnosis

To diagnose this issue, technicians should use a Scan Tool (wiTECH) and follow the appropriate Diagnostic Procedures available in DealerCONNECT/Service Library. It's crucial to verify that all related systems are functioning as designed. If any DTCs or symptom conditions other than those listed above are present, they should be recorded and addressed before proceeding with this bulletin. The 2024 Alfa Romeo Tonale PCM software update is specifically for the listed DTCs.

Important Warnings for Owners

• VIN List Requirement: This Rapid Service Update (RSU) only applies to vehicles that are specifically listed on the RSU VIN list. Owners should verify their vehicle's applicability through VIP or a VIN search in DealerCONNECT/Service Library.
• Battery Voltage: During the flash process, a battery charger must be installed to ensure the battery voltage remains between 13.2 and 13.5 volts. The charging voltage must not exceed 13.5 volts.
• High Voltage Chargers: The vehicle must not be connected to a high voltage charger while performing software updates.
• Interrupted Flash: If the software flash process is interrupted or aborted for any reason, it should be restarted from the beginning.

Repair Procedure Summary

The repair for the 2024 Alfa Romeo Tonale PCM software update involves reprogramming the Powertrain Control Module (PCM) with the latest available software. The general steps for technicians include:

1. Verify RSU VIN List: Confirm the vehicle's VIN is on the RSU list. If not, this bulletin does not apply, and further diagnostics are needed.
2. Check Current Software: Determine if the PCM already has the latest software installed. If so, the bulletin is considered complete.
3. Reprogram PCM: If the software is not current, the PCM is reprogrammed using the wiTECH Diagnostic Application. Any issues during flashing require submitting a ticket to the Helpdesk.
4. PROXI Alignment: After reprogramming, a "PROXI Alignment Procedure" is performed using wiTECH, found under the 'Vehicle Preparations' tab.
5. Clear DTCs: All Diagnostic Trouble Codes that may have been set in any module due to the reprogramming process are cleared using the wiTECH application.

This procedure ensures the PCM is updated to resolve the underlying software issue causing the MIL illumination and DTCs P2601-00 or P219A.

Required Tools or Parts

To perform this repair, technicians will require:

• A Scan Tool (wiTECH or Equivalent)
• A suitable battery charger to maintain voltage during the flash process.

Warranty Information

All repairs performed under TSB 18-054-24 REV. A are reimbursable within the provisions of the vehicle's warranty. The appropriate labor operation number should be used for claims:

• 18-19-06-9A: Module, Powertrain Control (PCM) - Inspect (0.2 Hrs)
• 18-19-06-9B: Module, Powertrain Control (PCM) - Inspect and Reprogram (0.3 Hrs)

Failure codes CC (Customer Concern) or RF (Required Flash) are used depending on whether the vehicle is on the RSU list or if the customer's concern matches the bulletin's symptoms.
