Just found this thread.Anytime I get on my car the codes come up and the rt front brake applies.I've been dealing with this since 7/08 when my 06 Z06 was still under warrenty.Today I put a new SWPS in and it did nothing to correct the problem.The dealer did the clip thing last summer,that didn't help.Where is the sensor that detects lateral movement? Does anybody know what it is really called? I've been told under the console but I can't seem to find it.I've gone thru 2 sets of rt front brake pads and 1 full set on the entire car.It started at 16k miles and now I'm at 29k miles.I've done the forms and was involved with Mike Packard at NHTSB in august of 08.Thanx, Tom

 

PLEASE post the DTCs that you get prior to turnig OFF the ignition.

Before the new SWPS I was getting service active handeling and traction control.Today The Active handeling lite would come on.It used to pull only right,today it pulled right and then left.This is driving crazy,I'm gona get the scanner from my snapon guy tomorrow and investigate further. Update: The scanner found alot of codes in the history to do with rear wheel speed sensors.I went through all the testa and cleared the codes.I haven't really been able to push the car cause of weather but when I did a little I would say 80% better. Still grabed a little but didn't throw the message.

 

I have a stock 2009 Corvette and the service active handling message comes on from time to time in the morning. When the temperature is below 50f. I have taken it to the dealer and they see the error code but they can't find the problem. They reset the code and I had them keep the car over night and check it the next morning with no problems found agaom. I am now getting the service active handling message showing again in the morning after sitting all night in the garage (below 50f). If I turn the car off and back on the message goes away. If I start the car later in the day when the temperature has risen the message doesn't show up.

Any ideas?
Thanks

I realize this is mainly a c6 issue, but a similar problem is coming up on my 2004 z06 so I am adding this info.

Symptom is a dic msg service AH and a code 1288, happens on sharp turns slow & moderate speed. No tele wheel on c5z's.

I got in there & turned the steering wheel while I observed the sensor. There was some movement at the 4 pin connector assembly that plugs into the sensor each time, about 1/8 inch as close as I could guess. Each direction. A tech I trust says this is normal on a c5 (the slight movement as wheel turns).

I pulled the connection apart & using a mirror inspected the 4 pins all were straight/clean/same length.

I inspected the female end and could see that the contact area is 4 tiny flat blades that are crimped to the wires and are loose captured in the connector.

I could also take the female end and hold the wires and wiggle them and see the blade contact area move around in the connector.

Very flimsy IMO for an important part of the tc/ah system. Should have been barrel pins as someone else posted.

All I could do is use some Rescue Tape (silicone tape that sticks to itself without adhesive) to wrap around the whole connection area and try to prevent looseness/movement.

If this is the problem & the tape fixes it then I will most pleased.

If the tape does not fix it, then I am not sure a new sensor would do much either as the same poorly designed connection would plug into it, unless they problem is actually internal to the sensor.

Are there moving parts inside the sensor? Does the sensor typically fail or is the problem usually the connector?

The red comb was already installed in my 2004 c5z as was a hold off / zip tie for the wire bundle. There was enough slack in the wire bundle.

BTW when this error happens I have never had braking applied by the car, only the service light & tc/ah OFF happens and the 1288 code.

I guess someone changed the software program to apply braking on the c6's, good job! SARCASM.

As the car ages & this stuff pops up, I get why several of my buddies bought Vipers.

If my fix works, I doubt I'll add an 04 to the NHTSB database as the braking problem seems to be a c6 one. Good luck all with this.

If all goes as planned (by GM) this will be another cluster **** like the c5 column lock "fixes" that will conclude when the last c5 goes to the government recycle/cash for clunker center in 2099.

It's unfortunate that a) not all of us can DIY, even with support from a forum and b) many/most of the dealers are pretty clueless when it comes to Corvette servicing, I avoid them as much as I possibly can.



UPDATE

Almost a month and no code since I secured the connection. I was getting it about 2x a week when it started. I think a good place to start, if you are capable of diy, is to firm up this connection any way you can, maybe even hard wire it. You may void your warranty with GM if you do this & are still under warranty. If that is the case you are doomed to suffer with GM & your dealer. Sorry.

 

Ive had this problem for years now, service active handling, car applies braking on its own causing itself to veer left or right.

I took the vehicle in last week and paid $104 for a diagnoses, the dealer told me this isnt part of the recall.

I contacted corporate and they informed me that they will not be fixing this issue.

Picked up my car today from the dealership and was informed that the my car's problem is not the wire but the actuator thats connected to it. (not gm's fault)

Could it be possible that the wires were pulled so many times that the actuator went bad? Im no electrician but if i keep pulling on a wire thats connected to an electronic unit the unit will short out or go bad.

Either way ive informed GM that i will take legal action, contact the nhtsa, and the media in order to shine light on GM's evil ways. Ive read many many of the posts here and have come to the conclusion that the recall is larger than admitted by GM.

POS company takes our money to get bailed out and turns around just to spit on our face.

F#$K GM!!!!

 

I forgot to mention this,

If there are any members here that feel they should be represented PLEASE send me a PM. Our fight against the tyrant GM will be much stronger if we stand together in large numbers. I want to visit the media with a strong and powerful case. Lets not let corporate shaft us little people.

 

I recently purchased a 2007 corvette with a telescopic steering wheel. One month later my service active handling light came on. Corvette is no long under warranty. If i were to take it to a chevrolet dealer what would i have to pay to get it checked or would they have to look at it cause of a recall. Please advice on what steps i should take

Start here and do it yourself. If this does not fix it, start reading all the thousands of posts on the subject to get smart on the topic. I would order the GM maintenance manuals as well. They come in a pack of 3.

Good luck

You would most likely pay one hour labor charge and get a service statement saying; :Could not duplicate customers complaint, THANK YOU for your money!

Unless the issue is continuously happening and throwing a DTC each time, there NOT going to be very helpful. They don't have a clue what causes the issue or this issue would not be a problem.

OR

They will replace something expensive and send you off on your way only to have it happen again. You will bring the car back again and they will do the same thing. You will keep bringing the car back to them until they say: SIR, we realize that you have NO MORE MONEY but,,,, we only have ONE MORE part to replace. The only part that we have not replaced is the radiator cap. The radiator cap isn't that much money and we are SURE that its the issue!

where is this SWPS connector located?

Does anyone know how to make this link a Sticky Thread or whatever it is called in the DIY section?

Thanks

Heres another photo:





I had the same issue and it seems like I solved it for the most part. I disconnected the sensor and used a small metal dental tool and slightly bent each pin rearward so that it would make better contact inside the female pins inside the harness connector. Have not had an issue since.

Give that a try.

I would LMAO if this were not so true.

 

They will first run your car's VIN to see if you fall in the cars recalled. Your car is an 07 so most likely no. At this point theyll give you the option to have a diagnostic check for $104 and if the check comes up showing the recall then yes they will fix and reimburse your diagnostic fee, if not......your stuck like me.

 

I replaced my SWPS and that didn't do a thing.I did find some history codes in the ABS system ck and got rid of them.It is better but not perfect.I'm gona do the yaw sensor in the console next and see if that fixes it 100%.I just have to find the yaw sensor part #.

 

I'm a new member just bought a 2005 c6 with 28000 k the first day i drove it, it flaged service active handling. Found this sight and read all the posts. Cked my car for the comb it didn't have it so i picked one up from a dealer and installed also fixed harness so it didn't move. This didnt work and i found out what it is like to change lanes to the left when you are not expecting it what a rush.took to dealer and the tech said it needed a steering wheel postion sensor so out with the old in with the new.this didn't work. So i started turning off the traction control & active handling and drove it that way,this seemed to work at least it went where i put it. After time went on i forgot to turn it off a couple off times and i noticed it wasn't doing it. Then i took a road trip about 800 miles while on the trip i got in to the wake up bumps on the edge of the road they work smile.then it started up again. Im going to hard wire the old steering wheel sensor with a lead thats a little longer and a new connector. I'm a motorcycle tech so it won't be to hard. Ill let you know what happens.[ FOUND OUT CHEVY HAD A NEW COMB FOR SWPS TOOK CAR TO DEALER TO GET IT INSTALLED. WHEN I WENT TO PICK UP CAR THEY TOLD ME THAT WAS NOT GOING TO FIX MY CAR NOW, THAT IT HAD A YAW SENSOR CODE. I FILED A COMEPLAINT AND TALKED TO THE GUY IN DC HE DIDN'T SAY ANY THING ABOUT SIGNING ANY THING.]

 

My last visit in for this problem was November. The GM engineer told the dealer to bypass a couple wires from the TCM to the ECM and run two new wires. Not sure which wires they were.

Wires were not run through the body but right down the torque tube tunnel. Wire had to be twisted/coiled so they were the same length as the originals. Puters detect voltage difference if not the same length.

Been a couple of months, several hundred miles and no SAH or STC yet or archived codes.

REPAIR NOTES:

Field Engineer inspected vehicle on XX/XX for repeat condition of communication faults. U2100, U2108, U2105, U2106 all stored in BCM with U2100 stored in EBCM. instructed to run new communication circuits from BCM to TCM using twisted pair 20 gauge TXL wire with soldering terminal ends on both sides. Restrung circuits 2500 and 2501 high speed GMLAN + and - communication terminals 2 and 20 at BCM C2 to TCM connector terminal 13 and 14. Routed new harness external to existing harness through bulkhead pass throughdown rear of engine, along torque tube to TCM. Secured harness with tie straps and placed in conduit for additional protection. Cleared codes and road tested."

 

Without going into the long story, as with mine, mine fits several of the same issues for STC/SHA/SES. Here is what the dealership found out with my STC/SHA/SES codes. And the fix GM Techs told them do. They give the level II Tech here in Houston the fix, of course, it was to cost me $300.00 dollars just to troubleshoot the fix and then wanting to charge me a $100.00 deductible. No, I took it back to the place who sold me the vehicle, Carmax for them to repair it, and they did at no cost due to it was still under their purchase warranty. I think this is a GM fraud having customers to pay for a repair GM knows exists, but fails to fix it. Even the recall I had done, did not fix it. However, so far the following fix seems to be holding and now going on for 4 months:

Codes:
U2100, U2105, U2107, U2108, comm codes

Fix:
Ck electrical inputs to ECM-BCM-EBCM
Input connector C180
Ck for any open & shut electrical
Drag test terminal-ECM-BCM-EBCM
Ck 2500 & 2501 from BCM-EBCm EBCM-ECM
Ck complete wiring harness
Ck modules before disconnecting (disconnecting what, I am not sure)

Hope this helps in your repairs. If you want, print these codes and fix and take it to the stealership and have them fix the problem.

NOTE....What I have learn, you must, must take it to a dealership at the moment the SHA/STC/SES lights activates, if the service dept is open. If so, DO NOT TURN OFF YOUR CAR until the codes are identified. Ask the tech II what codes were activicating. And, do your own research and the ask someone you know who can answer your questions as to what the codes are the fix is, such as on here.

 

Thanks for the info. I have the same problem on my 08 and it has been 4 weeks and still no part. Maybe in two to three weeks more. My rear brakes grab and no power. Almost go rear ended twice.
