Hello all,

I'm trying to troubleshoot the keyless entry on my 1992 SC300. I have replaced the ECU but still cannot get the unit to response to reprogramming the key.

Does anyone have the voltage values for the ECU terminals for the 1992 SC300? I have the 1996 diagram but it is different from the 1992. I suspect a wiring problem.

Thanks in advance

Couldn't figure out how to attach both on one reply, so here's the other one.

SAR41WY,

Do you also have the programming instruction for the 1992 model?

Thanks.

so what i did was i spliced into the lock wire since its a 12v pulse.. then i connected it to the piezo buzzer and grounded the other wire on the piezo and its in my driver fender.. so as long as i hit the button and hear one beep then its locked, if i click it and i hear nothing then its unlocked. but thats just me as long as i get one beep to confirm i locked my car thats good enough for me.. i might be converting to full keyless 2012 style soon no keys to open or start the car..
