Electronic Brake Traction Control Module
WARNING: This page is about a different car, the 1997 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
The EBTCM is mounted directly to the BPMV and is located at the rear crossmember. The EBTCM receives input from Powertrain Control Module (PCM), wheel speed sensors, steering sensor and brake switch. The EBTCM outputs information to PCM and BPMV.
The EBTCM determines when to activate the TCS and how to respond to a particular situation requiring TCS. The TCS intervention is achieved using one or more of the following: spark retard (timing), throttle closed or brake intervention. EBTCM also disables TCS when engine is off, with ignition on (when vehicle is being towed).
