Electronic Brake and Traction Control Module (EBTCM)

The EBTCM performs the following primary functions:
^ Detects wheel slip tendencies
^ Detects wheel speed differences
^ Controls the brake system while in the antilock or traction control (TCS) mode
^ Monitors the system for proper electrical operation
^ Provides dynamic proportioning for rear wheels
The EBTCM also controls the display of the ABS and traction control DTCs while in diagnostic mode. The EBTCM continuously checks the speed of each wheel in order to determine if any wheel is beginning to slip. If a wheel slip tendency is detected, the EBTCM commands appropriate valve positions to modulate brake fluid pressure in some or all hydraulic circuits. This action prevents wheel slip and provides optimum braking. The EBTCM continues to control pressure in individual hydraulic circuits until a slipping tendency is no longer present. The EBTCM continuously monitors ABS/TCS for proper operation. If an error is detected, the EBTCM can disable ABS/TCS and turn on ABS or Trac Off indications in the I/P, and driver information display or trip computer.
