Symptoms
This Technical Service Bulletin (TSB) from Nissan addresses specific Diagnostic Trouble Codes (DTCs) that may be stored in the vehicle's Telematics Control Unit (TCU). While the TSB primarily focuses on the presence of these stored codes, owners might experience issues related to telematics functionality or receive warning indicators if the underlying condition progresses. The primary symptom for technicians is the presence of these fault codes during a diagnostic scan.
Fault Codes / DTCs
Nissan has identified the following Diagnostic Trouble Codes (DTCs) that may be stored in the Telematics Control Unit (TCU):
| Code | Description | Module |

| B2E4B-06 | Telematics Control Unit Malfunction | TCU |
| B2E60-06 | Telematics Control Unit Malfunction | TCU |
| B2E61-06 | Telematics Control Unit Malfunction | TCU |
These codes specifically point to an issue within the TCU, which manages various communication and telematics features in your vehicle.
Diagnosis and Trigger Conditions
The presence of DTCs B2E4B-06, B2E60-06, or B2E61-06 in the TCU indicates a potential internal malfunction or communication issue within the unit. These codes are typically detected and stored by the vehicle's onboard diagnostic system. A technician would identify these codes by performing a diagnostic scan of the vehicle's control modules.
Repair Procedure Summary
Nissan has issued an amended Technical Service Bulletin (TSB) to address these specific TCU DTCs. While the full repair procedure is detailed in the TSB for technicians, it generally involves diagnosing the Telematics Control Unit to confirm the presence of the fault codes. The resolution for such issues often includes software updates or reprogramming of the TCU to prevent future occurrences or correct existing malfunctions. This TSB supersedes previous versions, indicating an updated or refined repair strategy.
