Power Distribution: Transmits power from battery/alternator to ECU, injectors, fan motor, A/C, lights, solenoids and sensors.
Signal Transmission: Carries sensor data (temp, pressure, RPM) and control commands between ECU, actuators and cabin switches.
System Integration & Protection: Integrates all electrical systems; protects against short circuit/overload via fuses/relays; EMI shielding for reliability.
Diagnosis: Enables ECU fault code reading for open/short circuit and connection issues.
