Nissan bulletin NTB20-085C
Nissan filed this with NHTSA as a service bulletin dated Aug 15, 2024, received Sep 4, 2024, about the electrical system. It names 18 model years (2020–2024). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.
What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationTELEMATICS CONTROL UNIT RESET AFTER AUTOMATIC COLLISION NOTIFICATION This bulletin has been amended. See AMENDMENT HISTORY on the last page. Please discard previous versions of this bulletin. SERVICE INFORMATION The Telematics Control Unit (TCU) has the ability to send an automatic collision notification when the vehicle is involved in an accident. Once an automatic collision notification is performed, the function becomes disabled and the TCU must be reset to re-enable the automatic collision notification function. Some models will store DTC B2E1B-97 for “Automatic eCAll locked� as “CURRENT� when this function is disabled. This bulletin describes how to reset the TCU after an automatic collision notification has been performed. For models with B2E1B-97 for “Automatic eCAll locked� set as “CURRENT�, complete the SERVICE PROCEDURE starting on page 2, and then erase DTCs after confirming the TCU condition is “UNLOCK�.

Common questions
Source: NHTSA, 49 CFR 579.5Is Nissan NTB20-085C a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the NTB20-085C repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does NTB20-085C cover?
The manufacturer filed it against 18 model years: 2024 Nissan Armada, 2023 Nissan Armada, 2022 Nissan Armada, 2021 Nissan Armada, 2023 Nissan Frontier, 2022 Nissan Frontier and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
