motronic m1.3

hi everybody
I have a problem with my motronic m1.3 (e30 m40 1990 AB44966) due to
uncorrect fixing CHECK ENGINE LAMP to pin15 of ECU,so it seems to me
that I spoilt my ECU ,cause I cant find even nessesary +5V on TPS and AFM
and what is the complete reason to replace the unit?
What more checks I have to make?
My RCX tester shows no problems
thanks stanislav
