quad driver error

[David C. Allen]

I have an intermittent ses light on my 84 sc2. It's mostly when it is 1st
started up and usually goes away when it warns up. I jumpered the connector
and it's a 26 error. Quad Driver fault. Can anyone tell me the procedure to
track down the problem?

Thanks!

Generally you get a second code along with the quad driver fault. Making a
repair to the other code usually clears the quad driver fault. Sorry I can't
help more. James

The QDM error probably indicates low resistance or a short on one of the
devices controlled through the ECM. On Saturns, this is apparently usually
either the EGR vacuum solenoid or the canister purge solenoid that cause
this..

Is it possible to use a multimeter to test the solenoids? If so can you tell
me the procedure?

Thanks!!!!!

Anyone know how to diagnose the faulty component?
