The P183A fault code refers to the Internal Mode Switch 2 D1 Circuit having low voltage. This code is related to the automatic transmission manual shift shaft position switch assembly, also known as the internal mode switch assembly. The internal mode switch assembly contains two sliding hall-effect switch assemblies that are attached to the control valve body within the transmission.

These switches indicate which position is selected by the transmission manual shaft. In this case, the P183A code specifically indicates that the D1 circuit within the internal mode switch assembly is experiencing low voltage.

This means that there may be an issue with the electrical connection or the switch itself.

To diagnose and fix this issue, it is recommended to use a scan tool to check the voltage readings of the internal mode switch assembly.

If the voltage is indeed low, the circuit or switch may need to be repaired or replaced. It is important to address this issue promptly to ensure proper functioning of the transmission.
