Summary

This article supersedes TSB 22-2210 to update the expected release date of the revised ABS module software. Customers who neutral (4-wheel flat) tow 2021-2022 Broncos equipped with an electronic brake booster (EBB) may report an inconsistent brake assist when a supplemental braking system has been installed. This may result from supplemental brake system set-up that does not account for the Broncos EBB system entering sleep mode (via the ABS module) after a pre-determined period of time following vehicle shut-down. This functionality is necessary to prevent battery drain. Enhanced software is under development to address this condition when the vehicle enters Neutral Tow mode. The new software is expected to be available in December 2022. Monitor OASIS for updates. Until the software becomes available, customers who meet this criteria may perform the procedures below to address this condition when neutral (4-wheel flat) towing their vehicle.

Owners of these vehicles have filed 64 complaints in the brakes category.
