just had this problem on my "new to me" 06 malibu. There is a tsb about this issue and it has nothing to do with the brake switch by the pedal everyone talks about. It's another connection over on the passenger side. Also fixes interlock problems trying to pull shifter from park. Will get tsb number and let you know Sat, Oct 24

ok here is what I found, #08-05-22-009: Intermittently Brake Lights (Stop Lamp) Do Not Function Correctly, Extended Travel to Shift Out of Park, Cruise Control Inoperative, DTC C0161/C0277 Set (Perform Repair as Outlined) - (Dec 4, 2008)


Subject: Intermittently Brake Lights (Stop Lamp) Do Not Function Correctly, Extended Travel to Shift Out of Park, Cruise Control Inoperative, DTCs C0161/C0277 Set (Perform Repair as Outlined)


Models: 2004-2007 Chevrolet Malibu, Malibu Maxx

2008 Chevrolet Malibu Classic

2005-2009 Pontiac G6

2007-2009 Saturn AURA




--------------------------------------…

Condition
Some customers may comment that intermittently the brake lights do not function correctly. Other symptoms may include extended pedal travel required to shift out of PARK, cruise control does not function correctly, and DTC C0161 and/or C0277 may be set.

Cause
The most likely cause of this condition is high resistance due to terminal fretting corrosion in the body control module (BCM) C2 connector (specifically pins C2-18, C2-31 and C2-59).

Correction
DO NOT replace the BCM for this condition. Disconnecting the C2 connector, adding dielectric silicone grease and reconnecting the C2 connector per the procedure below will correct the high resistance condition due to terminal fretting corrosion.

Remove the right side front floor console side trim panel to access to the Body Control Module (BCM).
Locate the C2 connector on the BCM.
Unlatch the C2 connector and disconnect the C2 connector from the BCM.
Reconnect the C2 connector back on the BCM and re-latch.
Repeat Steps 3 and 4 (this step cleans up the terminal fretting corrosion).
Using the Tech 2®, verify the brake pedal position sensor (BPPS) voltage is between:
• 0.88V - 2.11V (for 2004-2006 model years)

• 0.73V - 1.47V (for 2007-2009 model years)

Check for proper operation of the brake lights.
• If the brakes lights are operating properly, remove the C2 connector again from the BCM and proceed to Step 8.

• If the brake lights are not operating properly, proceed to Step 12.





Apply dielectric lubricant (clear gel) GM P/N 12377900 (In Canada, use P/N 10953529) on the BCM C2 pins (apply with a one-inch nylon bristle brush) on all the C2 connector pins (this will treat the pins against fretting corrosion).
Reconnect the C2 connector back on the BCM and re-latch.
Reinstall the right side front floor console side trim panel.
Using the Tech 2®, check that the BPPS ratio is equal to BPPS learned home when the brake pedal is not depressed.
• If they are equal, brake lamps should be operating correctly and no further steps are necessary.

• If they are not equal, perform the Brake Pedal Position Sensor Calibration procedure in SI to complete the repair.

Check the brake lights for proper operation. If incorrect, refer to SI and perform normal diagnostics.

I filled a report with the Highway of department safety. They said a recall may come if enough people participate in filling a report.

I dont understand why this is not a recall already! this is very unsafe and if enough people are having this same issue its a no brainer. I guess i am going to try the steps for unlatching the C2 connector and lubricating the BCM. I was told by a GM dealership in my area that the BCM needed to be replaced..... i don't see why i cant get a straight answer!

If they don't do any kind of diagnosis then they're just spouting nonsense. They first need to check it out. Speaking before knowing is the mark of someone who wants to separate you from your cash.

You can do the action yourself, even without the lube, and that action will clean the terminals so they make better contact. If fretting is the issue then it'll come back over time. The lube will probably slow it but not completely stop it.

I am of the mind that there ought to be a Federal law that requires brake lights to be turned on or off with a simple, effective, and trouble-free switch, instead of being computerized. But regardless of how it's done they should work properly. When it becomes a situation where a known issue exists across an entire fleet then it's time to act.

Several times on my '09 I couldn't get the cruise to work but it "corrected itself". I think that I actually corrected it unknowingly when I was doing some mods and unplugged that connector.

Wrong section, wrong generation too.

Idk if it was for the same reasons but my 00 was suffering from the Cruise not working issue. I would set it, cruise a few miles, then it would shut itself off. Somehow it 'corrected itself' also, and I have never touched the BCM. Its been a few years since this happened now. IDK what changed, but I'm glad it did.

@LTZgirl88, have you had your vehicle into the dealership within the last 30 days? What is the current mileage on your Malibu? May I have the VIN to look into this?

Having the right name might help.
I think it's the NTSB; National Transportation Safety Board.
Should be NTSB.GOV.

If that's not right, I'm sure someone will correct me.
