Hi eveyone. Had a lexus kicking my butt. come into the shop with a no crank/no com. All the fuses were good!! checked the 5v ref and it was 0. went to the car an hour later and has a 5v ref, could read the ecu but the dash went out while in park and neutral but not in r/d still no crank. went to the car a day later and had all dash lights but again a no com. scoped the prndl and had all clean waveform. car has gone now due to the customer putting a 2 day deadline on it. was wondering on thoughts on this. many thanks. darren
