How much of a draw?
If my info is correct, Fuse 6 should be a 15A for the Autolamp, Anti-Theft, Keyless Entry, Power Seats and Power Mirrors. I'm sure there is a minimal constant draw for the Anti-Theft and Keyless Entry modules at least.
My first suspect would be the Autolamp circuit, possibly due to a suspect headlamp switch. Do you typically have the Autolamp function switched on? It may be as simple as switching the headlamp switch off and manually operating the headlamp switch.
Hopefully others will chime in and offer their suggestions. But if it's not something simple, it may require digging through the EVTM and some process of elimination for a more thorough diagnosis.
Do you happen to have the shop manual and EVTM to reference?
