Toyota 2kdftv Ecu Pinout Diagram Best Exclusive 〈2024〉

🔌 ECU Connectors Overview

The ECU has four connectors:

1. Confirm your ECU part number – Look for 89661-0K... or 89663-0K.... If yours is a different variant (e.g., with DPF, Euro 5), pin assignments may shift slightly.
2. Always verify with a multimeter – For ground pins (A1, A2), check continuity to chassis. For +12V (A3, A4), confirm with key ON.
3. Injector pins are high voltage (~80–100V) – Do not probe with a standard multimeter in resistance mode while running. Use an oscilloscope or LED test light.
4. CAN bus pins (D1, D2) – Should have 60–120 ohms resistance between them with ECU unplugged (termination resistors in ECU and dashboard).
