P1594 Fault Code: Understanding The Description And Troubleshooting Steps
The P1594 fault code is related to the charging system voltage in an automobile. It occurs when the Powertrain Control Module (PCM) is regulating the generator field and there are no detected field problems, but the voltage output does not decrease as expected.
This code indicates that the charging system voltage is too high.
When this fault code is triggered, it means that the vehicle’s charging system is delivering a voltage that exceeds the recommended levels.
This can lead to various issues, such as damage to electrical components, shortened battery life, and potential safety hazards. It is important to address this issue promptly to avoid further damage and ensure the proper functioning of the vehicle’s electrical system.
