4 DTC's all at once?

[DMcBrideBoston]

I just got 4 DTC's on my drive home this morning....

Pulled with X Cal 2 - P0303, P0305 (I get those)

P1000 - OBD Systems Readiness Test Not Complete -------I don't understand this one

and

P1233 - Fuel Pump Driver Module Disabled or Off Line (Fuel Pump Driver Module)



Thanks

Search for the P1000--I remember seeing that one discussed here within the last six months or so.

I did, it doesn't say much....

You can ignore the P1000. It's for the smog police. Your ECM does an OBD systems readiness test that needs to be complete to give you a proper smog test. That's over-simplification...but you get the idea. There are a number of reasons that test may not have been completed....including your other codes you see. It should disappear once you fix the rest of the car.
