The P0695: Fan 3 Control Circuit Low code indicates that the control module has detected a low voltage condition in the control circuit for Fan 3. This can lead to improper operation of the fan, resulting in inadequate cooling of the engine and potential overheating. Low voltage can be caused by a faulty fan, wiring issues, or a malfunction in the control circuit.

P0695 Meaning
The P0695 code indicates that the voltage in the control circuit for Fan 3 is lower than expected. This low voltage can prevent Fan 3 from operating correctly, which may affect the engine’s cooling system and lead to overheating.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for additional related codes, particularly those affecting the cooling system or other fan control circuits. | OBD-II Scanner |
| Test the Fan 3 Control Circuit for Voltage | Use a multimeter to measure the voltage in the Fan 3 control circuit. Compare the readings with manufacturer specifications to check for low voltage. | Multimeter |
| Inspect Wiring and Connectors | Inspect the wiring and connectors leading to Fan 3 for any signs of damage, loose connections, or corrosion that could cause low voltage. | Flashlight, Multimeter |
| Test the Fan for Functionality | Test Fan 3 to ensure it is working properly. If Fan 3 is faulty or underperforming, replace it. | Diagnostic Tool, Multimeter |
| Replace the Fan if Necessary | If Fan 3 is malfunctioning, replace it to restore proper cooling system performance and prevent overheating. | Replacement Fan, Tools |
| Clear the Code and Test | After repairs, clear the code using an OBD-II scanner and test the vehicle to ensure that Fan 3 is operating correctly and that the code does not return. | OBD-II Scanner, Vehicle Manual |
