Application: 30-1002 NSX NA1 box

Problem: No vtec to rear bank head

What Ive done:

Energized both solenoids with direct 12vts. solenoids click...
Cycling the key on and off, you can hear/feel the front bank ONLY click...
Front does nothing...

Checked for 12vts at the ecu pins D17 and D9 (vtc sol.) @ VTEC CHANGE OVER, only one pin is 12vts....

Do I have a bad ecu?

 

do u have the sub harness for the 2nd solenoid?

from the 1002 manual, "We have supplied an expansion harness to connect to this plug which you must attach to your factory harness. To do this you plug the Yellow wire into pin D7 and the Yellow/Blue wire into A19 on the factory chassis loom (see diagram).
There should not be any wire in place in these slots. Attaching this sub harness does not prevent you from putting the factory ECU back into the car. Just use the normal VTEC plug on the factory ECU if you do."

 

yes we have all that........

main problem was...no voltage out of A19

We bought a new AEM and problem is solved. thanks guys.
