hi my name is ***** ***** I can help you. the SCV gets it's signal from the ECU but before you condemn the ECU check the connectors and wire resistance from ECU to scv. also for continuity. may have broken wire. Is there any trouble lite on? hope this helps. let me know

Customer: replied 11 months ago.
Thanks I will check wires, but which ecu pins connect to the scv.
Expert:  Peter Bagley replied 11 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.

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. .
