P0695: Cooling Fan 3 Control Circuit Low
What to do
Driveable. On a hybrid, mention any high-voltage system warning or reduced performance, since a third fan may serve the battery rather than the engine.
What this code means
A third cooling fan control circuit reading low. Three-fan arrangements appear on large engines and on hybrids, where one fan may be cooling the battery or inverter rather than the engine — worth establishing which before assuming the consequence.

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
