IC BUS service campaign 26101

IC BUS filed this with NHTSA as a service campaign dated May 22, 2026, received May 8, 2026, about the electrical system — 2 documents under this number. It names 10 model years (2021–2026). A service campaign is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.

What the bulletin says

Source: NHTSA's summary of the manufacturer's communication

Certain International® trucks and IC BusTM CE Series buses may have out of date BCM programing that may cause erroneous fault codes after a vehicle sits for 2 or 3 days.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5; the full text comes from the manufacturer or a dealer. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. Quote it at a service desk; it is what the dealer’s system is keyed on.

Common questions

Source: NHTSA, 49 CFR 579.5

Is IC BUS 26101 a recall?

No. A service campaign 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.

Is the 26101 repair free?

A service campaign is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.

Which vehicles does 26101 cover?

The manufacturer filed it against 10 model years: 2021 IC BUS Cesb, 2022 IC BUS Cesb, 2023 IC BUS Cesb, 2024 IC BUS Cesb, 2025 IC BUS Cesb, 2026 IC BUS Cesb and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
