1. Trisco palm scanner says "no car data" for sfi and bm systems, after new upper wiring harness installed. What does this mean? is lh moduel bad? are the wires bad?

2. If the two ground wires behind the headlights are broken, will they keep the car from starting?

3. After replacement of upper wiring harness the onboard push-button led dtc reader stopped working completely.

4. Home brew dtc scanner gave code 5 for pin 7 - can databus: message from ea/cc/isc module faulty (n4/1); message from abs/asr module faulty (n30/1); message from lh-sfi module faulty (n3/1). What does this mean?

5. Upon installation of upper wiring harness, I think I broke the camshaft position sensor. Will this keep my car from running as well?

Thanks in advance for the help.
