Some 2019-2020 Mustang vehicles equipped with a 5.0L engine and a MT82 manual transmission may exhibit a concern of inoperative reverse camera and inoperative reverse lights. The vehicle will also exhibit messages in the IPC warning various driver assist systems not available and/or DTCs P086A, P086B, P086C, P086D, P086E, P08AE, P08AF, P08B0, P08B2, P095A, P095B, P095C, and/or P095D stored in the powertrain control module (PCM) with or without an illuminated powertrain malfunction (wrench) indicator. DTC U0401 may also be present in the anti-lock braking system (ABS) module, side obstacle detection control module LH (SODL), side obstacle detection control module RH (SODR), image processing module A (IPMA) and/or parking aid module (PAM). This may be due to a concern with the gear shift sensor, gear shift sensor circuits and/or calibration in the PCM. To correct this condition, follow the service procedure to reprogram the PCM.
