Has anyone encountered these codes


I recently installed a rebuilt ETA for my 95 sl500. The original problem was the ARS light was on all the time, so I replaced the ETA and the engine wiring harness and also the ASR pedal switch.

Now the ASR light comes on first thing in the morning but goes away after a restart. The only code coming up now is

#30 ASR only can data bus to ea/cc/isc control module interrupted

#30 no data from ea/cc/isc
n 4/1

Can anyone tell me what I need to do? an ddoes anone know who is a good ecu rebuilder

Thanks
