DTC Error code P0480 Fan Control Circuit
Just took my BAS re-map off ready to go to the dealers for a service etc......

Anyway checked the DTC's and cleared them. Got the usual re-map oddities but one is persistent and does not clear.

P0480 is "Fan Control Circuit" - does any one have any idea what this could be. I can't recall the last time i heard a fan kick in.

I have a 110 Utility with a/c and Webasto block heater

Going to Sahara soon so would like all fans and things to work properly

Did you cut into the cabin heater circuit so that the Webasto can take control when it gets the water temp up to a certain temp? If so, it's probably nothing to worry about.

Check fuse 29, 20amps and fuse 42, 10amps in the main fuse box. Also the Relay for the Compressor clutch Air conditioning (A/C) (R181) and the relay for the cooling fan R117. Check the connections at the A/C compressor on top of the engine and the ac switch pack located under the centre console on LHS. The PCM will log P0480 if there is an issue with the cooling fan as it is used on A/C models as part of the engine overheating protection strategy.

so checked a few things - fuses OK, a/c relay OK and compressor audibly kicks in with a momentary drop of engine revs. Couldn't get the a/c fan to kick in - probably 'cause it is so cold. will 'hard wire' it to see if it is operational when i get a minute. Going in for a service soon - will get LR to give it a once over.

DTC still showing......at least it is the only one Very Happy

Thanks
