Some 2020 Mustang GT500 vehicles may exhibit a battery drain concern when the customer applies the electric parking brake after turning the ignition off. This may be caused by the operation of the antilock brake (ABS) module software. To correct this condition, reprogram the ABS module using the latest version of the appropriate Ford diagnostic scan tool. For claiming, use causal part 2C219 and any applicable labor operations in Section 2 of the Service Labor Time Standards (SLTS) Manual.
