355 Slow down lights ? 5.2 1997

[phib]

Right so having taken my delightfull 355 out yesterday for the first time in months and months had a lovely drive no issues at all.

Comming onto my drive ( it was a hot day) the slow down light came on (solid light) and stayed on the car runs perfectly starts drives etc etc

Now I have don the following turned off the battery turned off the battery disconnected the ecu behind the drivers seat , re connected the ecu behind the drivers seat.

And still have a light, the light comes on from cold so I suspect its more of an eleictrical issue rather than hot cat as the cats are stone cold.

Any one got any ideas what to try next ? I know you can reset the ecu or ecus but not sure quite how to do it or if that will help

Thanks

What do they look like and how can you test the / reset them ?

[jleroux]

the oxygen senders are poking out of the exhaust either side of the cat. the cat ecu's are a pair of green/blue boxes (about the size of a mobile phone) in the rear corners of the engine. I think you need an SD2 hookup to view/clear the error though.
