U0111The first one deals with a lost communuication with the control module. These are new ones for me too. They all seem to be related to the data link communication to the ECM. Nothing specific.

So should I go over every connection with a fine tooth comb and see if there are any problems? Or would I be wasting my time?

Before you do that, I would like to ask a counterpart of mine here for his suggestions. He is an expert with Saturns.

Just to add to this one code dtc p1a7b is starter/generator control module temperture sensor performance. Its a hybrid code your best bet is to take it to the dealer really hard to talk you thru the repair. You need special tools and hybrid repair knowledge.

Battery engine control module lost communication with bcm and pcm.

You have an 8 yr 80k warranty on the hybrid system. I, at least have seen these codes but never got a chance to track them down due to warranty.

I think you need to call the dealer and run your vin to confirm.

As far as your trip, get a rental from the dealer or a rental agency. You dont want to break down on your trip or rush a repair for your car.

We have a saturn guy on board here but have not seen him on yey. Maybe he can help more.

Good luck

So get this, last night I took off the "hybrid" cover that covers the 12V battery and the electrical components for the hybrid, and pretty much just with out taking anything off, wiggled all 3 connection on the ECU, I just got in the car and everything works perfect, the hybrid system is charging and assisting, the only thing that still bothers me is that for the last 2 years it keeps throwing a P-0449 witch is a E-VAP code and its been to the dealer like 20 times because of it and no
one can figure it out, but other then that, I have to thank you guy's, you were a big help :)

The battery under the hood isnt for the hybrid system. As far your code p0449 does the code reset quickly?There really isnt a bulletin I can think of or find for the vue.I can tell you how to test for power to the vent solenoid and also jump the vent solenoid to see if its opening and closing. But to see if the computer was commanding it on and off you would need a tech2 scan tool the one gm uses at the gm dealers. But from the code its going to be the vent solenoid itself the wiring terminal tightness or the computer itself.

I know, I never touched the battery, the ECU is right under the hybrid cover, and just pretty much I wiggled the 3 connectors on the ECU and it just all started working again, for the EVAP code, if you clear the light it can come on with in a day, and some times when I clear it it wont come on for a week, or in till I put gas in the tank, and I have already replaced the gas cap 4 times.

There was a campaign where saturn modified that harness that maybe where your problem came in. As far as the code p0449 it has nothing to do with the gas cap or evap leaks its all about the evap vent solenoid and its circuit.

I checked the vent solenoidal, and it works good, so I suppose that explains why I have a random harness with like 8 wires cut by the alternator. The car also has a leak code for the longest time, but I just remembered there was a recall or a TSB on a EVAP hose that it went in for in the spring, now do I have any argument with GM that this is potentially a recall/ TSB?

Those cut wires is probably just when they did that campaign I mentioned in a earlier post. Can you post a pic of the cut wires?Also no you dont have a claim for a recal or tsb there has to be a lot of the samething happening on a lot of the vues for that. So how did you you test the vent solenoid on the fuel filler neck?

That looks like the campaign the wires as far as the vent solenoid by the filler neck all you had to do is turn the key to the run position and one wire should have power and you would ground the other wire to open and close it. There would be no reason to run power to it unless you had a issue with the wiring. So did one wire have power with the key in the run position?

There shouldnt be a ground untill the computer grounds the wire to command the vent solenoid.
