car died on road today loud popping noises like misfire our backfire while driving then i let of on the gas and she died. I got her towed home and pulled codes this is what I got from the ccm
31=LCD Data Circuit shorted to B+ or CCM internal open.
33=Data Clock Circuit shorted to B+ or CCM internal open.
35=Data Strobe circuit shorted to B+ or CCM internal open.
37=M Clock Circuit open or shorted to B+ or CCM internal open.
no engine codes
I did have a pinhole leak near the radiator upper return hose was leaking all day I was out away from home found it leaking refilled the fluids and had been on the road heading home for about 15min watching the gauges when it happened.
The car did not overheat and oil pressure and temp was good.
New to all this but have been reading alot about peoples problems for the last month my first guess is optispark. The codes dont say optispark. What can I do now to troubleshoot? I was planning on pulling the opti. The popping was similiar to when my ecm was bad when the feds wouldnt let my car run but I would try pry revving it. Please any help pointing me in the right direction would be huge. by the way car is 1993 coupe.
