Thanks for your info. I didn't really get chance to have the sensors checked. A few days ago, when I had my flat tire fixed, the tiremen found out that both sides of the front axle assembly were loose due to the worn out joint. Luckily,after I had the two little peices(arms?) replaced, all the lights and annoying sound were gone. It explains that when the front axle assmbly has worn out joint, car system will detect a wide turn even when you are driving straight. Therefore,any slight turn on highway will make car system feel like a abrupt turn and activate the traction control system and warn you with the beep beep beep....
I still need advises for another two problems.
1. VSC ABS VSC OFF light . I bought my car from an auction with its front(right side) hit. Beside the bodyjob, everything functioned properly except the VSC ABS VSC OFF light were on. The electrician found the broken wires for the right side front wheel sensor and reconnected them. The light were off right after that.It was good for only a few weeks, then the light came on and off from time to time. I assumed it was due to a loose connection. However,when I wanted to make sure by reconnectting the wires firmly, the light were still on. I even tried connectting the two wires in opposit way, it didn't work. And it's still the on and off situation. I checked the driver side connection, it looked fine. Could it be connection or sensor(s) problem?
The sensor the wires connected to is the cnly one we can see behind the front wheel. My machnics friend said
that one must be ABS sensor, then where is the speed sensor?
2. No electric and died engine. One night when I was driving and hit a bump,all lights dimed out for a second and came right back on. Then when I stopped at the traffic light, all lights dimed out again and engine died.I tried to jump it, it just "click, click "weakly. When I tightened the battery terminal, I could start it again. The question is: When engine is still on, loose battery connection wouldn't affect engine at all, would malfunctioned starter or alternater make the running engine died and car out of electric?
I would like to have some advises or ideas of what the problems could be before I have to see machnics.
Thanks in advanve for helps.
