P1596 Fault Code: Understanding The Description And Troubleshooting Steps
The P1596 fault code refers to a problem with the speed control switch in the automobile.
This switch is responsible for controlling the speed control system, which is electronically controlled and vacuum operated.
The speed control system is integrated into the Powertrain Control Module (PCM) and consists of five switches on the steering wheel: ONOFF, RESACCEL, SET, COAST, and CANCEL.
The P1596 code specifically indicates that the speed control switch is always in the high position, meaning it is constantly sending a signal to the PCM that the switch is engaged, even when it is not. This can result in issues with the speed control system and may require further diagnosis and repair.
