Special Service Message · SSM 55242

This is a Special Service Message, not a recall. SSMs are informational notes Ford sends dealers about a known condition or a change in procedure. They are not repair orders, and they don't by themselves change what is covered.

Published: Oct 13, 2026
Applies to: Mustang Mach-E (2021–2026 model years)

Summary (official text)​

Some 2021-2026 Mustang Mach-E vehicles may exhibit an illuminated brake warning indicator with diagnostic trouble code (DTC) C1013:92 stored in the anti-lock brake system (ABS) module. This may be due to brake pads being out of specification for compressibility, which can alter the brake system's pressure-volume and falsely indicate an internal hydraulic failure. The pinpoint test for C1013:92 in the Workshop Manual (WSM), Section 206-09 has been updated to include a preliminary inspection and a brake pad swap to determine if an out of specification set of brake pads are the root cause.
