Check the Output Signal from the ECM
The first step in diagnosing Subaru Code P0692 is to check the output signal from the ECM. The ECM (Engine Control Module) calls the radiator fan relay control circuit to activate the cooling fan. If the ECM does not send out the proper signal, the fan will not start, and the Subaru will throw a Code P0692 error.

Check for a Short Circuit in the Radiator Fan Relay Control Circuit
The next step is to check for a short circuit in the radiator fan relay control circuit. A short circuit in the radiator fan relay control circuit can cause the fan to fail to activate, resulting in a Code P0692 error. If a short course is found, replacing the radiator fan relay is essential to fix the issue.
Check the Main Fan Relay
When the ECM sends the signal, the main fan relay activates the cooling fan. If the main fan relay is faulty, the fan will not start, and the Subaru will throw a Code P0692 error. To diagnose this issue, it is essential to check the wiring harness to ensure it is appropriately connected.
Check the Sub Fan Relay
The sub-fan relay powers the cooling fan when the ECM signal is received. If the sub-fan relay is faulty, the fan will not activate, and the Subaru will throw a Code P0692 error. To diagnose this issue, it is essential to check for poor contact.
Conclusion
Subaru Code P0692 is an error code that several different factors, including an output signal from the ECM, a short circuit in the radiator fan relay control circuit, or poor contact, can cause. To properly diagnose and repair this issue, it is essential to take the necessary steps to identify the exact source of the problem. By understanding the causes and solutions associated with Subaru Code P0692, you can take the necessary steps to diagnose and repair the issue quickly and effectively. With proper diagnosis and repair, the Subaru Code P0692 can be easily rectified, allowing you to get back on the road without further issues.
