TC/Abs Ecu Input Signals
TC/ABS ECU receives signals from 4 wheel sensors which provide input on wheel speed. TC/ABS ECU also receives signals from monitoring circuit for hydraulic pressure and brake fluid level. Pressure switch in TC block sends signals to TC/ABS ECU with information on whether the brake is activated and whether TC or ABS mode is operative (manual transmission version only). See Fig 1. Signal from pressure switch is compared with input signal from brake light switch. TC/ABS ECU also communicates with ETS ECU. TC/ABS ECU is located on battery shelf. ETS ECU is located under driver's seat.
