Electronic Control Unit (Ecu)

The ECU controls all functions of the TCCS. The ECU receives signals from the data sensors and switches. Signals are processed by the ECU for controlling the Electronic Fuel Injection (EFI), Electronic Spark Advance (ESA), Idle Speed Control (ISC), Electronic Controlled Transmission (ECT) and EGR systems.

The ECU contains a fail-safe function used in case of a data sensor or switch failure. This function provides a back-up system to provide minimal driveability. The "CHECK ENGINE" light will also be activated during this function.
