What does the P0700 fault code mean?

[LeRichard]

P0700 indicates that the transmission has requested the malfunction indicator lamp to illuminate. This fault code simply informs that there is a malfunction in the transmission and the fault light is on. If it persists and is accompanied by transmission shudder, it is necessary to analyze the data stream, which is usually caused by a transmission sensor. Below is the relevant information: 1. Malfunction Indicator Lamp: The Malfunction Indicator Lamp (MIL), also known as the Check Engine Light, is designed to illuminate a yellow or red engine symbol on the dashboard when the control module detects a fault. This fault code indicates that the powertrain system (ECU) has received a request from the transmission control system (TCU) to illuminate the malfunction indicator lamp. 2. Precautions: After troubleshooting the vehicle, it is generally necessary to clear the fault codes. When clearing fault codes, it is essential to follow the specific method prescribed for the corresponding vehicle model. Under no circumstances should the negative battery cable be disconnected solely to clear the fault codes.
