I am fairly new at doing any serious car work other than oil/filters, brake shoes, that sort of thing. Looking at my battery in our 2006 2.2L HHR I see there is a 50 amp fuse. Can I pull this rathaner than take the battery terminal off the neg. post to reset the cel light? Neverr seen this fancy setup at the battery that this HHR has concerning the negative to ground post.

That fuse is there to protect the BCM or Body Control Module, one of the two main computer modules in an HHR. You can disconnect the negative battery cable for about 30 minutes to an hour and that will clear the codes that are causing the CEL.

But another way to do it is to take it to an auto parts store like Advance or Autozone, have them pull the codes and reset the CEL. You'll get a printout of the code/codes that have been set so you can see why the CEL came on in the first place and correct the problem.

 

Mike- I thought the auto parts couldn't clear codes for liability reasons.

Read them, Yes..

 

I've heard that they do more than I've heard that they don't depending on who you talk to, maybe someone here who's had codes pulled recently can clear things up in that regard.

If I've made a misstatement I do apologize jima59.

If it weren't midnight I'd just call up my "buddies" over at the Autozone and get their official answer.

 

It has been about two years ago I had Advance auto pull and clear a code on my wife's 96 Pontiac Sunfire GT. This was about a month before she tradded it for her 09 HHR.

 

I ground (with my die grinder) the negative connection right next to that because the metal is painted which isn't a good ground, but after that my car starts to stall out after it warms up (50 seconds if its cold). Do you think I may have bumped it? I didn't think I did. Can it be simply replaced or does it have to be programmed?

 

Tighten any fasteners, test the fuse and push it into place firmly, spray the area with Fluid Film

 

That fuse is NOT connected to the ground post. It provides power to the BCM computer. It just happens to be mounted near the ground. The fuse is connected to +, you have sent it to ground.
Do you think the people that designed the car are stupid? Just maybe it is painted on purpose?

 

If it's connected to the ground cable, it's not the 50 amp fuse, it's the current sensor, part of the charging system.

 

The fuse "looks" like it goes to ground.
