NHTSA Service Bulletin 11027297: 2024-2026 International Hv
Official manufacturer communication context for 2024-2026 International Hv, with affected products, buyer checks and links into Carchieve recall, problem and VIN research.
Reviewed June 2026 from NHTSA manufacturer communication and service bulletin records. Carchieve is independent and not affiliated with any vehicle manufacturer or government agency.
This document is intended to provide supplemental information for concerns with brake light switches and pressure sensors used by the BCM and PIM module to determine if the operator of the vehicle is applying the service brakes. All S13 vehicles are equipped with BCM feature 597483 (BCM PROG, BRAKE SWITCH, Use With Brake Application Pressure Switch). 597483 uses a normally open brake pressure switch that closes with 2-6 psi of air pressure and a brake application pressure sensor. When the switch is closed or the pressure sensor reads higher than 4psi, the BCM considers the brakes applied and will broadcast that over the J1939 networks to other modules. The S13 also includes a redundant brake switch that is wired directly to the PIM. This switch is normally closed and opens with 2-6 psi of air pressure. If the S13 ECM believes the brakes are applied from one of these brake signals, it can reduce or completely cut throttle input.
What this bulletin may mean before buying
Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.
