2021-2024 Nissan Remote Command DTCs B2E4B-06, B2E60-06

Symptoms

Owners of certain 2021-2024 Nissan vehicles may experience problems with their NissanConnect® Service remote commands. This means features like remote start, remote door lock/unlock, or vehicle status checks might not function as expected through the NissanConnect app or service.

Fault Codes / DTCs

When these issues occur, a technician inspecting the vehicle's Telematics Control Unit (TCU) may find one or more of the following Diagnostic Trouble Codes (DTCs) displayed as "CRNT" (Current):

• B2E4B-06
• B2E60-06
• B2E61-06

These codes specifically point to a communication or functionality issue within the TCU related to the remote services.

Diagnosis and Trigger Conditions

Nissan has identified that these DTCs and the associated NissanConnect remote commands malfunction are caused by an issue with a cloud-server that interacts with the vehicle's Telematics Control Unit (TCU). This indicates the problem is external to the vehicle's hardware itself, stemming from the backend service infrastructure.

Important Warnings for Owners and Technicians

Nissan has issued critical advisories regarding this specific issue:

• "Do NOT replace the TCU. Replacing the TCU will not resolve the concern."
• "Do NOT replace any parts."

These warnings are crucial as they prevent unnecessary and costly parts replacements that will not fix the underlying cloud-server problem. Owners should be aware that if a dealer suggests replacing the TCU for these specific DTCs, it contradicts Nissan's official guidance.

Repair Procedure Summary

For technicians, the repair procedure involves a specific communication process with Nissan rather than a physical repair. If a customer reports issues with NissanConnect remote commands and the specified DTCs are present, the technician must send an email to [email protected]. This email must include:

• The technician's name
• Phone Number
• Dealer Name and Code
• The vehicle's VIN
• All DTCs displayed as CRNT
• A photo of the "Unit ID Information" screen, which can be found in the vehicle's infotainment system under Settings > NissanConnect® Services > Unit ID Information.

Nissan advises allowing up to 48 business hours (Monday-Friday) for a response to this email, which will provide the next steps for resolution. This process confirms that the solution is managed by Nissan's backend support, not through a vehicle hardware repair.

Owner Action

If you own a 2021-2024 Nissan Sentra, Pathfinder, or Rogue and are experiencing problems with your NissanConnect remote commands or have had these DTCs diagnosed, you should contact your authorized Nissan dealer. Inform them about the specific symptoms and mention Technical Service Bulletin NTB21-037D. Your dealer will follow the prescribed procedure to communicate with Nissan and resolve the cloud-server related issue affecting your vehicle's remote services.
