How is fault code P0693 fixed?

A typical diagnostic sequence used by mechanics, provided here for educational reference only. Diagnostic work should be performed by a qualified mechanic with the appropriate tools and training. 1. Pull all stored codes and read them together. A P0693 sitting next to a coolant temp or other fan code tells you a lot about where to dig first 2. Check the cooling fan fuse. If it's blown, fit a new one and watch it. A fuse that pops straight away means you've got a dead short to find, not just a tired fuse 3. Have a proper look at the fan wiring and connectors. Unclip them, check for corrosion, water, melted plastic or chafing where the loom rubs the body 4. Swap the fan relay for a known-good one of the same part number. Half the relays in a modern fusebox are identical, so you can borrow one from a non-critical circuit to test 5. With the ignition off, give the fan blades a spin by hand. If they're stiff or seized, the motor is your problem, not the relay 6. Get the engine up to temperature and back-probe the fan control connector. You want to see roughly 11.5 to 12.5V when the ECU commands the fan on. No voltage points upstream, voltage but no fan points at the motor
