Green "test" connectors.

Really_Soaked · 04-29-2001, 09:19 PM

There are two green connectors, one on the passenger side and one on the driver's side under the dash. If you plug them in the fans cycle and the coil doesn't get juice. Anyone know the purpose of these?

The Green connectors serve 3purposes that I'm aware of;
1st) When the car is new and in transit to the dealer, they are connected. This puts the engine in a "lean run" mode to prevent the plugs from fowling. When the cars are in the factory, port, transit, etc. they are not driven enough to warm them up, maybe 50 feet at a time.
2nd) They are referred to as the "D-check" connectors (Dealer check or Diagnosis check). A technician will connect them and then perform certain tasks in a particular order and this will cause the ECM to test itself.
3rd) As you found out, when they are connected, it causes the various fans, relays, solonoids, fuel pump, to cycle on-off. A technician can use an instrument called a Subaru New Select Monitor (NSM) to isolate individual components and cycle them by themselves. This is known as Forced Drive.

Thanks for the answer. Would this, for any reason cause the coil not to have power?

No, plugging these connectors together will not prevent the engine from starting/running. As I wrote previously, this is used as a diagnostic. If you have no power at the Ignition coil, you have another problem.

I also heard that the green connectors on the driver's side are used (it AUS cars, probably JDM cars too) in conjuction with some black connectors in the area to do a "proper" ECU reset (read MRTs site about it)

but nobody I know of has been able to locate said black connectors, just the green ones.
