The vehicle may also have an illuminated anti-lock braking system (ABS) indicator with diagnostic trouble codes (DTCs) C0020 and U3003 in the ABS module. This may be a result of water/moisture intrusion into the battery junction box (BJB). The BJB is located under the hood of the vehicle. This water/moisture intrusion may be related to the BJB cover not installed completely or broken cover tabs/locking fingers allowing water/moisture into the BJB. To correct the condition, follow the Service Procedure to inspect for water/moisture intrusion into the BJB and replace the BJB and cover if water/moisture intrusion is found.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10235151-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10235151-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10235151"}],"url":"https://open.wenmarpro.com/makes/ford/f-600/2021/bulletins?code=C0020"},"related":{"components":[],"bulletins":[],"recalls":{"may_apply":true,"recalls":[],"lookup":{"nhtsa":"https://www.nhtsa.gov/recalls","tc":"https://wwwapps.tc.gc.ca/Saf-Sec-Sur/7/VRDB-BDRV/search-recherche/menu.aspx?lang=eng","maker":null}}},"url":"https://open.wenmarpro.com/makes/ford/f-600/2021/codes/C0020","note":"The bulletins listed name this code in NHTSA's summary, or are about the same components.
