Here's the scoop. For the past couple of weeks, it has been very cold here in CO (relatively speaking) it's been registering in the single digit. It's been nearly impossible to start the truck in single digit temps. The only way I can get it started is to plug it in and heat it up for few hours before hand.
This morning, the breaker went off on the plug the truck was plugged into and the heater never checked on. Tried to start it anyway and the battery went dead. Had to use the battery charger to recharge the battery and reset the breaker and heat engine heater for just over an hour to be able to start the truck.

Also, earlier this week, I receive the latest version of the Edge module (no attitude) from Edge products from an RMA. I've been running it level 3 for the past couple of days and didn't really take the truck to the limit. But, I can definitely feel the addictive added power.

So, back to recharging the battery and starting the truck...
I figure, I have the original AC Delco batteries on an 02 so it's time to replace the batteries. As I pull out of my driveway to go to buy new batteries, I see the SES light is on... C R A P !!!
The truck drives fine, Edge is kicking nicely. I figure I got that stupid code you get when you use the heater in temperature not so cold. But, I swing by the Autozone and the codes P0374 and P0700 are registering.

From my searches, it sounds like P0374 is related to high resolution timing device signal not being seen during cranking by ecm. Could this be related to Edge or the battery being dead?
P0700 is related to limping the tranny. Very likely Edge set to level 3. I didn't think level 3 was bad but i better turn it down to level 2.

So, what do you guys think? Did the dead battery have anything to do with these codes? Or, do I have the Edge set too high? How do people run Edge w/ Attitude at level 5 or 6. I'm not ready to get a Suncoast quite yet.

When the guy at Autozone read the codes, he must have reset the codes b/c now the SES light is gone. Let hope that it stays that way... I'll tune the level to 2.

:help: would be much appreciated.

You'd know if you limped the tranny. At anytime did it downshift and stay in 4th gear and the ses light come on?

 

[sjl_dmax]

No. It acted perfectly normal. Except for the SES light...

 

[SteveFord]

I'd say if it dosen't happen again it could be a glitch from the batteries running low.:think:

 

[sjl_dmax]

Thanks Steve. I'm hoping that was the case. We'll see if the code comes up again after I change the batteries out. Edge Level 3 is safe isn't it?

 

[SteveFord]

From what others have stated level three as long as your not pulling a heavy load should be fine. Just watch the 4th to 5th gear wide open throttle shifts. Every tranny is different some limp easier than others. Mine hasen't yet and I had no slip according to the attitude when I had my predator stacked 65 and edge on level 1-3 pulling my job trailer 4500#'s. With the bastard stack it will be a gaurantee limp in 5th.

 

[sjl_dmax]

Alright. I'll keep it in level 3 for now... Thanks Steve.

Well, here's the update. I went out this morning to replace the batteries. To my jaw dropping surprise, I noticed the passenger side battery's ground terminal was disconnected. The only thing I can think of is that the body shop that fixed my truck un-hooked the ground terminal off of that battery and forgot to put it back on. This means that my truck was running only on 1 battery for the past 3 weeks. No wonder the truck couldn't start when it's 0 degrees outside.

Regardless, connected the battery up and the truck started just fine at 27 deg. So, I drove to Autozone to get the batteries tested just to be sure. For some reason, both batteries tested as bad. Are those testers accurate?

I'm puzzled...
As far as the DTC codes are concerned, I can only attribute them to the battery getting totally drained.

Stupid body shopCensored :shootself
