Thanks for the info, but just now i went inside but not found anything. :hmmmm:

reset back the ECU...
drive around the block...
see if the error code appears again or not...

perhaps that error code was an old one...we never sure...

and make sure you run the diagnosis correctly...

just to be sure...go here :

Finally Chin just get me out of small hill. Thanks bro and I notice that in Club4AG there wrote:
"Code 51 (AC compressor switch signal) is erratic by nature and will sometimes come on without malfunction."

Anyway, I just sort out the hose after the throttle body to supercharge intake got leak. I will try to replace the hose and see what the result out. Thanks a lot.

The real problem is:
ISVC - is faulty

The hose leak and change no help any improvement. Totally waste time.... hahaha XD
