Contour Enthusiasts Group Archives Forums General Troubleshooting ABS Light

Here is what I found with the Manual.

When there is a variance in the speed reading for an extended period of time, Code C1222-Wheel Speed Signal Mismatch sets.

There are two types of ABS systems.
Mecatronic 3 and Bosch 5.3 ABS.
They use different fuse amperages, so by looking at your fuses, you can tell which system you have.

From looking at the diagrams, it looks like the underhood fuse #7 will kill the ABS system and reset the memory.
The Bosch 5.3 ABS system also ties into the PCM, so you may also have to reset the PCM to clear history codes.

The other fuses are for the pump motor, ABS light and Stop Lamp Switch.

Here are all of the fuses...
