I will try to answer this. If you mean codes in the on board computer, it takes 100 miles of driving to make the computer readable if the battery has been disconnected for some time or the error codes have been erased from the ECU (computer).
No. Just reconnect the battery and let the car idle for 5-10 minutes and then start driving the car. The car will relearn your driving habits after a week or two. . . .
== my 2 cents== The memory in the computer is lost when the battery is disconnected for an x amount of time on this model car. All the self test the car has run (monitors) need to be performed again by driving the car. IF the check engine light was on, it will come back after it fails the test that it had previously failed for....most likley.
If battery is disconnected or replaced, OBD system needs to reboot which may take up to 200 miles of driving. System should be fine after that.
the battery is dead and needs to be charged or replaced, or it could also be the alternator is going bad
There is nothing to reset. You already reset the PCM back to factory settings when you disconnected the battery to replace it. Now you must drive the vehicle normally so it will relearn your driving habits, conditions you drive under, climate, etc.
Is the battery/alt warning light on? if they didn't disconnect the battery while the starter was being replaced and they accidently shorted the battery cable out it could have damaged the regulator of the alternator some of the Delphi regulators are very sensitive to that, but if it tested normal at the parts place, does it run down while driving or while sitting?
I had a 1999 Grand AM same thing happened to me. A while after that i was driving and the radio lost power, then the power steering. I had the alternator and battey replaced and that fixed the problem.
Sounds like the alternator is gone.
Replace the battery or the carbarreta
check alternator belt may be slipping.if the belt isworn or glazed replace it if problems is still there replace alternator.
No, a pcm, bcm, or ecm will not reset itself while driving. On the otherhand it will do checks when you start the car to make sure everything is operating properly. If something is not it will light up the infamous check engine light.(pcm) There is nothing for it to reset when you replace the battery. It does not loose it's memory when the battery is disconnected anymore than a computer in your home looses it's memory when you unplug it from the wall outlet. Therefore there is nothing to reset.
hook it directly to your battery with a inline fuse and see if it works
Your battery is weak, or your your alternator is not charging battery.
Yes why not, you can recharge your truck PC by driving around. To recharge the PC first the truck battery should be charged. Driving recharges truck battery because every truck has a power generator inside it but you cannot recharge your truck battery if it is not working properly the acid level of the battery should be maintained properly. Better you check your battery before recharging battery.
You have a bad battery or you have a bad alternator.
Alternator is defective or battery has a dead cell.
Both are giving the data about storage capacity of a battery. For Ex. 12V 7AH Battery will run 7 hours if you are driving the load of 1Amp continuously. But 12 12AH Battery will run 12 hours if you are driving the load of 1Amp continuously.
The oil and battery lights might be showing on your shogun when driving due to an electrical problem. A mechanic can properly diagnose the problem.
Could be a bad rebuild unit or a bad battery. It could also be the type of driving and accessories that the unit supports.
Your car has to perform a drive cycle in order for the self diagnostics to complete it's test. If your car had a dead battery recently or the battery was disconnected recently it won't pass emissions until it has performed a drive cycle.
check battery cables at battery may be lose.
Don't believe a word AutoZone tells you. My battery died so I went there and they tested my battery and alternator and told me it was the battery. So I bought a new battery and 2 days later, dead again. Went back and they tested again and THIS time, it was the alternator. I went nuts on them and ended up getting both my battery AND alternator for free for their mistake that left me stranded at 12am.
Many things can cause lag while driving at a low RPM but not at a high RPM even if it is not the vacuum hose disconnected from the EGR valve as it could be the fuel filter. It can also be the park plugs.
