While it is a generic code, the specific repair steps may vary depending on the make and model of the vehicle. If you find that a code P has been stored in your OBD-II vehicle, it means that the powertrain control module PCM has detected a malfunction in a specific circuit related to the torque converter brake switch. This code is only applicable to vehicles equipped with automatic transmissions. Automatic transmissions in mass-produced vehicles have been electronically controlled since the s. Other vehicles use a separate transmission control module that communicates with the PCM and other controllers via the controller area network CAN. The torque converter is a type of fluid coupling that connects the engine to the transmission. When the vehicle is in motion, the torque converter transfers torque to the transmission input shaft. This allows the engine to idle without stalling. The lockup torque converter, used in OBD-II equipped vehicles, allows the engine to lock into the transmission input shaft under certain conditions. This typically occurs when the transmission has shifted into the highest gear, the vehicle has reached a certain speed, and the desired engine RPM level has been achieved.

If the RPM level increases when the brake is depressed, the TCC is operational and the brake p0703 ford is deactivating it properly Failure of the TCC system to operate can cause major transmission damage.
