Some 2020 Transit vehicles built on 31-Jul-2020 and through 14-Aug-2020 may experience a forward collision warning light with diagnostic trouble codes (DTC) B1433:54 and U2100:00 set in the cruise control module (CCM) due to being improperly equipped with a CCM. To verify, electrically disconnect the CCM. Once disconnected, perform a self-test on all other equipped modules. After a self test, start the vehicle to determine if the warning light is present. If other modules do not set loss of communication DTCs with the CCM and the warning light is no longer present, remove the CCM and seal/tape the connector to prevent water intrusion and relocate the harness to prevent rattles.
