P189C Fault Code: Understanding The Transmission Control Module Performance Issue
The P189C fault code is related to the transmission range command message performance in a vehicle.
Control modules in the vehicle monitor communication on the serial data circuits during normal operation. These modules exchange operating information and commands.
Each module keeps track of transmit and receive error counters, which increase with detected errors and decrease with error-free messages. When the transmission range command message performance is not up to standard, the P189C code is set, indicating a potential issue with the transmission range command message.
