Service Active Handling Message 2007 Vette
The service active handling light comes on and when you stop the engine it won't restart. When you try to start it a message comes on put your foot on the brake but my foot is already on the brake. I have taken it to the local chevy dealer 3 times and i just got it and it did it again. The dealer replaced the brake pedal sensor and repositioned and recalibrated the brake pedal and sensor. Any ideas about what is wrong or how to get the dealer to fix it.

Did they happen to mention what code they saw when they scanned the car with the Tech 2? There are a number of things that can just cause the Service Active Handling message turn on without any other messages being displayed. The brake pressure sensor is one of them but there is no indication it would cause the subsequent foot on brake message you are seeing. The sensor they did replace gets its voltage from the BCM and does send signals to the ECM so if it isn't working correctly there could be a faint chance of that circuit causing you issue. However, the pedal sensor is only one of the things in that circuit that cause the issue and generally it would set the Service Vehicle Soon message Vs Active Handling.
I looked up the Foot on Brake message and it links to the ABS description but I didn't see anything in the description that described keeping the engine from starting.
One of the functions the EBCM provides to the ECM is an indication of rough road. This lets the ECM determine if there is a misfire problem or the car is just bouncing around. The brake pedal position sensor signal might be part of that feedback to the ECM. Are there any indications of engine misfire?

Need to know what all codes were there. I wish I could find a code-reader that would read the bcm codes and all modules. I don't have an extra $3500 laying around for a Tech2

Bill[/QUOTE Thanks. No indication of misfire

going to revive this thread... im getting the same code and my brake lights are sticking on too. I have a very deep background in automotive and electronics so its not like im completely stumped. By feeling up under there it seems like there is a reed type switch that triggers the brake lights. There is a bit of forward and reverse play in the pedal that takes no effort to move. Pretty sure that if this slop was removed that the problem would be cured.
Anyone have experience with this? Will the warranty cover this work?

I replaced the brake light switch first and still came up with the problem . If you remove the panel under the dash and look at the motor that powers the telescoping steering you will find that the torque in the motor pulls on the connector. I added more wire to the harness and it solved the whole thing. What this has to do with the brakes or handling system I don't know. All I know is it fixed my problem and the car works great now.

Thank you! I figured this was the problem as I have the wheel extended as far out as possible. I might see how much a new harness costs and modify that... but working in automotive I know the mark up on service parts is insane.
Fireman0697, ss the brake light switch on the C6 just a normal plunger style momentary switch?
Looks like ill be doing this tonight

Its not a plunger type at all. the switch has a fork like extension that goes on a post which is on the brake pedal. where the connector goes into the switch is a three wire connector.
the extension rocks back and forth as the brake pedal is pushed making contact with connections in the switch.

From your memory is there any room for adjustment? It seems as if there is a tad bit of play in my brake pedal that makes the brakes light up. Is there adjustment in the sensor or its mounting so that i can make it react to brake pedal movement later then it is now?
I looked up a schematic of the sensor and it doesnt show enough detail.

I didn't see anyway possible to adjust the switch or the bracket. Its a plastic piece mounted to a metal bracket. If you look under the dash it is easy to see but a bear to change unless you are a very limber person. I had my thirteen year old grandson do most of the removal and install I checked it after I let him do it and it worked perfectly. The switch only cost me 17 bucks. It was a nice try but didn't remedy the problem. Good luck

I just got my 2007 Vette from the dealer and they checked terminal tightness at BCM connector C2 terminals3,1, 18 and 59. repaired loose connection at terminal 18. This stopped the handling light and brake light problems and the car is like a new one. It took them three days to find it so I hope I save time for someone with a similar problem
