2021 Nissan Rogue ECM Reprogram for AC, Transmission Issues

Nissan has initiated a Voluntary Emission Service Campaign, identified as P2A07, to update the software for the Engine Control Module (ECM), Transmission Control Module (TCU), and Shift Control Module (SCU) in certain 2021 Nissan Rogue vehicles. This Nissan Rogue ECM reprogram aims to resolve various performance and warning light issues.

Symptoms

Owners of affected 2021 Nissan Rogue (T33) vehicles may experience one or more of the following conditions:

• "Air Conditioner (AC) blowing warm air at idling condition."
• A warning message to "apply the parking brake when the vehicle is stopped and is in gear."
• A "CVT malfunction" light appearing when driving.
• A noticeable delay when shifting the transmission from Reverse to Drive.
• Difficulty shifting the transmission into Neutral.
• The "Malfunction Indicator Light (MIL) ON" on the dashboard.

Diagnosis / Trigger Conditions

These symptoms are linked to incorrect software calibration within the vehicle's control modules. The issues can manifest under specific driving conditions, such as idling, being stopped in gear, or during normal driving, leading to the illumination of warning lights or performance anomalies.

Repair Procedure Summary

The corrective action involves updating the software for the Engine Control Module (ECM), Transmission Control Module (TCU), and Shift Control Module (SCU). Dealers will use Nissan's diagnostic system to reprogram these modules. No physical parts are typically replaced during this procedure.

Required Tools or Parts

To perform the Nissan Rogue ECM reprogram, technicians will utilize the following:

• CONSULT III+: Nissan's proprietary diagnostic tool.
• ASIST: Nissan's service information system, which provides the updated software.

No other parts are required for this campaign, as the remedy is purely software-based. However, if the reprogramming fails and a module needs replacement, rental assistance may be provided.

What Owners Should Know

Nissan will begin notifying owners of potentially affected vehicles via U.S. Mail in August 2022. The service, which involves the Nissan Rogue ECM reprogram, will be performed free of charge for both parts and labor. The estimated time for this corrective action is up to two hours, though the actual time your vehicle is at the dealership may vary based on their schedule.

Important Warnings

• Not a Stop Sale: Affected vehicles are not subject to a stop sale order.
• Not a Safety Recall: This is a Voluntary Emission Service Campaign, not a safety recall.
• Safe to Drive: Nissan has confirmed that your vehicle is safe to drive even if it is experiencing these conditions.
