Official summary
This article supersedes TSB 20-2364 to update the production fix date. Some 2020 Explorer/Aviator/Police Interceptor Utility vehicles built on or before 24-Dec-2020 may exhibit an illuminated anti-lock brake system (ABS) warning indicator lamp with diagnostic trouble code (DTC) C0020 stored in the ABS module. It may not be necessary to replace the ABS module/hydraulic control unit (HCU) to resolve DTC C0020. This may be due to a poor ground connection and/or improper plating on the attachment bolts at G108. To correct the condition, follow the Service Procedure to replace and properly tighten
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
