Fault code?

[nickf1]

I own a 2003 Clio 1.4 16v Dynamique+ which has thrown up its management light with the following fault codes:

• 285 - Fast fan control short circuit to ground
• 285 - Fast fan control open circuit
• 285 - Fast fan control

I'm assuming a switch has failed, presumably refering to the radiator fan rather than interior fan. However, the car does not overheat.

I've tried to search but have had no luck. Could anyone shed some light?

Thanks in advance!

Maybe this resistor or the wiring to it..

Thanks Steve. I did come across that thread but could not work out where that part would be located on the car. Any idea?

On the radiator fan cowling.

On the radiator fan cowling.

Perfect, thanks for the photo. Do you know if it's just the one screw holding it in place?

Yes, but you do not need to remove it to check continuity with a multimeter.

Does the car have air con?

Found this, so I could be on the wrong track anyway.

It has air con.

Thanks for the diagrams. I've cleaned up the contacts on the associated relays and fuses. However, the EML light is still on.

What I don't know is if the EML light will go out after X miles if I had fixed it, or if the code would need to be wiped.

So is the fan working now?

It should run at half speed all the time the aircon is on.

I did not know that it ran at half speed with the air con on - I'll have to try it out, thanks!

 

[nickf1]

Just checked - the fan does come on with the air con.

So fan works.

Try pulling the plug off the coolant temperature sensor, the fan should run at full speed.

did this ever get fixed ?

i have the same fault codes
