Just installed new front and rear brake pads ( turned front rotors) on my 99 SLS. I can't figure out how to reset the message, "Change Brake Pads" on the Driver Information Center. Tried the "Reset" function but the message reappears. Any ideas?

Did the new pads come with new sensors?

Check your codes to see which of the four sensors is grounding out on the rotors.

Reset is not going to do what you hope it will do.
You have an open circuit in the brake pad wear sensor circuit somewhere. Either your pad wear sensors are disconnected at one or more of the chassis connectors, or your pad wear sensors are worn to the point where the wire loop inside the sensor is open.
If you purchased OEM ACDelco brake pads, new pad wear sensors were part of the pad set.

Thanks for the quick info, guys! The replacement brake pads were not AC Delco, I bought Wagner and they did not include anything but the new pads and hardware. I re-installed the sensors and little spring retainers just as they had been on the old pads. The sensors are the little rounded ends of the sensor lines that fit in the top of the new pad, right?

 

[Krashed989]

Yes they are, but once they sense that the brake pads are worn, they will always sense that. You need new sensors to go with the new pads. Sadly, they are only good for one use.

You can eliminate the DIC message.
All you need to do is determine which pad wear sensors do not have continuity. This will be easy if you can remember which corner(s) had the most pad wear and the fronts would be the "usual suspects".
Jumper the pad wear sensor chassis connector and the DIC message trigger point will not know that particular pad sensor is open. Of course, this will defeat your early warning radar system.

I just had this problem. Cut that damn wires and tape them together. I turned my car off 5 or 6 times and the damn message went away.

OMG, why bastardize such a nice car. Do it right.

Jumper the pad wear sensor chassis connector and the DIC message trigger point will not know that particular pad sensor is open. Of course, this will defeat your early warning radar system.

Just curious - how to get access to the sensor chassis connector without removing the wheel and brake pads?
