Back again guys! SM just quit working other day. Been trouble shooting and heres what I got. Start car and it displays start up info, then shows --- --- then goes to sleep so its not recieving a signal from ECU. I read where after it goes to sleep you can ground signal wire and it should "recycle" start up display....it dosent.
I also read where som ECU's fail in the area where it send signal to ADL port, and also the low speed fan relay and TCC solonoid. I have some new relays coming, the old ones seemd to work as they should.
Is there a way to test the signal wire to see if it is sending data, or do I need another SM to figure that out?
as always, thanks for any help!
