Theory Of Operation

WARNING: This page is about a different car, the 2016 Jeep Wrangler and 2015 Jeep Wrangler. However, it is still accessible from the selected car via links, so may be relevant.

The ABS Module detects an invalid signal between the master cylinder pressure applied and the Brake Lamp Switch Output Circuit for two minutes. If the Brake Lamp Switch Output circuit is still active with no pressure applied, code C1000 is set.
