Electronic Brake Control Module: Description and Operation

DESCRIPTION
The EBTCM is located in the rear compartment behind the lefthand seat. The EBTCM receives information from the ECM, wheel speed sensor and TPS module. The information is output to the ECM, modulator valve assembly and the adjuster assembly. The EBTCM determines when the TCS or ASR system should be actuated through timing retard, throttle close down and brake intervention. The ignition retard signal is based on engine RPM. Engine RPM information is received from the tach filter circuit. The EBTCM controls the amount of adjuster assembly output and throttle rate. As required, the EBTCM controls the modulator valve assembly pressure. The EBTCM will disable the TCS or ASR system when the ignition switch is in the On position but the engine is not running.

NOTE: The EBTCM must reset its idle position detection capabilities whenever a new throttle position sensor or throttle body is installed.
