Control Unit

Power for the control unit (terminals "A1" and "A2") is received via the EFI main relay on Swift models. Back-up control unit power to terminal "A16" is supplied via the main fuse. Control unit distributes power to all sensors except oxygen sensor and speed sensor, which generate a voltage signal of their own.
