Thanks I will check wires, but which ecu pins connect to the scv.
Expert:  Peter Bagley replied 4 months ago.

if you can give me your "E" mail I can forward the schematics for that and you have to do all checks from the wire side as not to damage the delicate ECU connectors it should be a low voltage going to the SCV

Thats my email. I checked the wiring for continuity, and they okay. May be I have check the ecu. Kindly send the diagram.
Expert:  Peter Bagley replied 4 months ago.

unfortunately there is no ECU check itself that's why you have to be careful to check all perimeters around it I will dig up the diagram and send it off to you best of luck. your "E" mail address didn't come through , I have the diagram for you just waiting for e mail address. .
