Driving along, everything normal then get a chime and instrument cluster warning lights flashing. End up with the E-brake warning light and Brake Warning light staying on. If you try to set the E-brake, you can hear the motor run but the brake won't stay engaged unless you hold the switch up for about 5 seconds. What says the brain trust as to where to look first. Everything works fine except for setting the E-brake.

It's not a guess, if the motor and the switch work it must be the control module. And using logic it's obvious that the module would be the only thing that would keep the brake pads engaged. The switch just turns the parking brake on or off and the motor pulls and releases the parking brake cable, but it's the control module that sends a signal to the motor to hold the cable tight.

The module may just need calibration as opposed to replacement and if the module is in question. You may want to try this first before getting to involved in buying parts.

Calibration without Scan Tool
1. Ignition ON, apply and hold the brake pedal.
2. Push and hold the electric parking brake switch down for 5-6 seconds.
3. Release the electric parking brake switch.
4. Momentarily push the electric parking brake switch down.
5. Remove the EPB MODULE fuse and reinstall.
6. Apply the electric parking brake.
7. Release the electric parking brake.

Before I spend any $$$ on a potential electrical repair, I learned early on to remove/reinstall the associated fuse first. In most cases that's all that needs to be done. Good advise and I hope it works.
