This can also happen due to problems in the wiring harness or connector, or the power in the battery is low. It is important to note, however, that this code doesn’t always mean the battery is disconnected, but the battery power to the PCM is low. The PCM (powertrain control module, also known as ECM or engine control module in other makes of cars) sees it as an interruption of power, which then sets the code. The code simply means the battery is disconnected within the last 50 cycles, but when the motor is started, the voltage on the battery considerably drops. It is set during the DRB III Quick Battery Disconnected procedure. Specification of the definition, troubleshooting, and repairs still vary from one make and model to another.Įrror Code P1684 is detected when the TCM (Transmission Control Module) is disconnected from the battery power B+ or ground.

This error code is a manufacturer-specific trouble code, meaning it does not apply to all cars makes. Error Code P1684 is defined as Battery Power To Module Disconnected.
