The U0325 code is a communication Diagnostic Trouble Code (DTC) that is set when the Auxiliary Heater Control Module is not configured properly. This fault code is caused by software incompatibility with the Auxiliary Heater Control Module. No external circuit diagnosis is involved in this fault code.

It occurs when some devices are not properly configured with specific software, serial numbers, vehicle options, or other information.

What are the possible causes of the engine light being on when the automobile fault code U0325 is detected?

If the engine light is on and the automobile fault code U0325 is detected, it could be due to an auxiliary heater control module programmed with incorrect software or a faulty auxiliary heater control module. To fix this issue, one should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can one visually inspect the related wiring harness and connectors to fix the U0325 fault code?

If you’re experiencing the U0325 fault code, which is indicated by the engine light or service engine soon warning light turning on, there are a few things you can do to fix it. Firstly, check the possible causes, which include an auxiliary heater control module programmed with incorrect software or a faulty auxiliary heater control module. To fix the issue, visually inspect the related wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.

Is it possible for the U0325 fault code to be caused by damaged components other than the Auxiliary Heater Control Module?

While the U0325 fault code is commonly caused by an Auxiliary Heater Control Module programmed with incorrect software or a faulty module, it is possible for other damaged components to trigger the code.
