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 the ground cable fasteners.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10186415-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10186415-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10186415","components":[{"id":"brakes","name":"Brakes","parent":null},{"id":"electrical","name":"Electrical system","parent":null}],"codes":["C0020"],"topics":[],"vehicles":[{"make":"FORD","model":"EXPLORER","year_from":2020,"year_to":2020,"match":"exact","vehicle_ids":["2020_ford_explorer"]},{"make":"LINCOLN","model":"AVIATOR","year_from":2020,"year_to":2020,"match":"exact","vehicle_ids":["2020_lincoln_aviator"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
