SSM 49433

Some 2020-2021 Explorer/Aviator/Police Interceptor Utility vehicles may exhibit an illuminated anti-lock brake system (ABS) warning lamp with diagnostic trouble codes (DTCs) C0031, C0034, C0037, and/or C003A. This may be due to metal contamination on the wheel speed sensors or wheel speed sensor rings. Verify that all wheel speed sensors and wheel speed sensor rings are free of metal contamination before replacing them. Refer to Workshop Manual (WSM), Section 206-09 for diagnostics.
