engine management system warning light

I just wheeled my bike out and washed it. now the engine management light on the gauge is on. any advise out there.

Probably water got in the electrics.. let it dry out?

thanks

i,ll try it again this morning after leaving it over night. if still on i,ll run it up to triumph.

triumph shop

well its raining hard this morning but had to pick up back rest from triumph shop anyway so i drove. While there i asked about the censer problem and engine management system light on. Well i have K&N filters and i took them off to wash out also. The front filter has the inlet air temp censer in it and i disconnected it. But i started the bike up after washing without the censer connected so the bike has found a fault and needs the fault to be cleared by the diagnostics plug in. They will clear the fault for me at no charge.
