Symptoms

Owners of a 2021 Nissan Rogue (T33) with the PR25DD engine may experience the Malfunction Indicator Lamp (MIL) illuminating on the dashboard. This condition is accompanied by the Diagnostic Trouble Code (DTC) P0404 being stored in the Engine Control Module (ECM). Importantly, this issue typically occurs without any noticeable drivability concerns.

Diagnosis / Trigger Conditions

To confirm if this bulletin applies to your 2021 Nissan Rogue MIL ON P0404 issue, a technician will first verify that the MIL is illuminated and DTC P0404 is stored in the ECM. They will also confirm that there are no drivability concerns present.

The next step involves checking the current ECM part number using the Nissan C-III plus diagnostic tool. The bulletin provides a comprehensive list of affected ECM part numbers, all beginning with the prefix "23761-". Examples include 23761-6RA2D, 23761-6RA2E, 23761-6RA6B, and many more. If the vehicle's ECM part number does not match one on the provided list, this bulletin does not apply, and further diagnostic steps would be necessary.

Repair Procedure Summary

The primary action to resolve the Nissan Rogue MIL ON P0404 is to reprogram the Engine Control Module (ECM). This procedure involves several critical steps to ensure a successful update and prevent damage to the control unit.

Before initiating the reprogramming, the technician must prepare the diagnostic equipment and vehicle. This includes connecting an AC adapter to the CONSULT PC, ensuring the CONSULT PC has internet access and ASIST software is synchronized with all updates. All external Bluetooth devices within range must be turned off, and all vehicle electrical loads should be turned off, except for the hazard warning lamps which should be on. A battery maintainer or smart charger must be connected and set to reflash mode to maintain battery voltage between 12.0 V and 15.5 V during the process.

Once these preparations are complete, the ECM is reprogrammed. After the reprogramming, the vehicle requires a 10-minute drive to meet specific Idle Air Volume Learning conditions. These conditions include achieving an engine coolant temperature between 70-100°C (158-212°F), ensuring battery voltage is above 12.9 V at idle, and having the transmission warmed up. Following this drive, the technician must perform Throttle Valve Closed Position, Idle Air Volume Learning, Accelerator Closed Position, and finally, erase all DTCs. A printout of the C-III plus screen showing the ECM part numbers before and after the reprogramming is then attached to the repair order.

Important Warnings

Nissan emphasizes that these bulletins are intended for use by qualified technicians, not for "do-it-yourselfers." Qualified technicians possess the necessary equipment, tools, safety instruction, and know-how to perform the job properly and safely. Owners should not assume a described condition applies to their vehicle without proper diagnosis by a Nissan dealer.

Owner Action

If your 2021 Nissan Rogue is displaying the MIL and has a stored DTC P0404, it is recommended to schedule an appointment with an authorized Nissan dealership. The dealership technicians have the necessary diagnostic tools and software to confirm if your vehicle's ECM is affected and to perform the required reprogramming. This procedure is typically covered under warranty if your vehicle meets the specified conditions.
