I would report the failure to NHTSA and have the GM dealership do the repair.

 

Will do - was just trying here before the dealership. I have read numerous stories of guess and replace when it comes to SRS which gets really expensive really fast.

 

When I look up that code, it's called left side impact sensor. If so, that's the sensor inside the door. Usually in the bottom rear corner.
I found a number of secondary codes, but no code 00

 

Thats the same thing I got however I replaced that sensor and it continued with the same symptoms same issue. To add to this, if I shut the truck off and restart it the SRS clears and is fine until I open the door again while the truck is running

 

Ok, so opening the door is the clue.
A lot of times, changing the part is not the answer. With SRS codes, the secondary code tells you what to look for. However, I couldn't find anything for a code 00.
If your having a problem when the door is moved, I'd suspect a wiring problem. You could have a broken wire, a bare wire going to ground.
But, a wire causing a problem only when the door is open.
This makes me think there is a problem in the hinge area, when the wires enter the door.

 

Thats what my brother thought too - I did a quick inspection of the wiring and it is still within the protective plastic tube and protective felt tape. I do not see any chaffing - do you think something could have happened within the tape. Is there a way to test that without stripping the tape back?

I appreciate your help

 

GM has reduced the wire sizes so small that many have found open wire in a perfect insulation condition . these defects have been found in many other areas .. could be this is your problem ...

 

follow the wiring back.. With the battery disconnected and the vehicle battery cables shorted together use an ohm meter to locate if the srs door wires are open . wires will be color coded so check at door then where the wires enter the vehicle . move door see if the ohmmeter reacts to the door movements.

if there is a defect with the wiring make a NHTSA report stating your findings.

 

Thanks JCat - Ill report back the findings. It will probably be sometime next week as I leave tomorrow for the long weekend.

 

Your going to need to open the door panel again and look at the way it's wired.
Note the colours of the wires, and then trace them. They may go to the door control module.
If they go straight to the hole in the door frame, look outside the door (in the wiring bundle) for those two colours. Look very carefully at the wires, feel them, stretch them (gently) see if you can tell if the copper moves inside the plastic.

Appreciate that - yes it is a straight run back into the kick panel - I will need to do all of the above plus trace it to a connector inside the truck

 

Hey guys,

So good news - I have isolated the problem. You guys were correct in the broken wire within the insulator. I haven't stripped out the harness yet to check it out but long story short - door open no connection door closed connection. I will report this to the NHTSB and report back once the new harness is in and tested OK. I appreciate your guys help - you saved me a lot of time.

 

your report back to us will be used by many others that see this type issue . like I said others have had wire failures with no insulation damage. this may cause a huge GM recall if there is much more wiring manufacturer defects.

since it is an air bag circuit I am sure NHTSA will be very interested .

good troubleshooting ...

 

Thanks Jcat and if it was for you guys I'd still be chasing. I'll keep the thread up to date as things progress

 

Harness replaced and symptoms are gone. No SRS light so it was a broken wire WITHIN the insulator with no signs of damage.

For future reference if anyone needs it there is a new part number.

Front door harness (w/Power locks)- Literally every single cable in the door
2010 Silverado 1500 5.3L 4x4 Crew Cab
Part No: 22912643

 

thanks for the feedback . you did save a huge amount on this repair.

 

Very much so - harness was only $90 on Amazon. When I called the dealer they said they would have to diag it which you know they would have replaced the sensor at $180 then paid for more drag time to find the harness which was $170 from the dealer. I hope this helps someone in the future

 

you should report this failure to NHTSA and keep the defective GM harness .. they may want to look at it .

 

your gonna have to take the protective sheath and any tape off the wiring. countless have found broken wires hidden behind the tubing in otherwise perfect condition.

Methinks you might have missed this.

Reported it and kept the harness just incase. No response from NHTSA

 

NHTSA being a federal agency operates under this current administration at snail speed. It may take a few months until they send you some documents and perhaps they may ask for a picture and answer some questions .. I reported my 2000 silverado 1500 defective parking brakes it did take some time before they got back to me. eventually they had recall and some sued GM in class action lawsuit.
with all the defective issues on these new vehicles they must be quite busy..
like those Takata air bags. they are still installing the defective part in vehicles made now . all new vehicles with Takata inflators will be called back for replacements.

Good point - ill tuck it away for a few months just in case

 

That air bag list now includes my wife's '08 Saturn Astra and my '09 Avalanche.

 

the reason the air bag recall grows is because these devices when they age become very unstable. could blow just by the internal defect. in humid weather they are more unstable.

some manufacturers are paying for rental cars until these owners can get the repair done [part issue]
some say pull the fuse !

 

The recall 2 weeks ago (which included my vehicle), said just that. As the bags age the active ingredients, the chemicals that cause the explosive inflation, become less stable.
The recall also said, areas with high temps, wide temp changes and high humidity, were higher risk.
The recall also said parts are not in stock.

 

buying a new vehicle now is a problem because of these defective air bag parts still being used.
living in humid areas is apparently causing some to not use the vehicle or pull fuse.
I doubt Takata will ever supply all the replacement parts.
