| Pin | Signal | |------|-----------------------------| | C1 | CAN-H (OBD / diagnostics) | | C2 | CAN-L | | C3 | Check engine light (W) | | C4 | Glow plug indicator | | C5 | Brake switch signal (STP) | | C6 | Clutch switch (if manual) | | C7 | Neutral position switch | | C8 | AC request signal (ACMG) | | C9 | Electric fan relay control | | C10 | Alternator L-terminal | | C11 | Vehicle speed sensor (SPD) | | C12 | Immobilizer coil (code) | | C13 | K-line diagnostic (ISO 9141) | | C14 | Starter signal (STA) | | C15 | Fuel heater relay | | C16 | Glow plug relay 1 | Determines cylinder #1 top dead center (TDC)

The 2KD-FTV utilizes an ultra-high-pressure common-rail fuel system. The ECU triggers the injectors via an external Edu (Electronic Driving Unit) or internal high-volt drivers. Injector trigger signal outputs.

| Test | Pins | Expected | |------|------|----------| | Backup power | B23 → B24 | 12V always | | Ignition on | C17 → B24 | 12V with key ON | | Main ground | B24 to chassis | <1 ohm | | Sensor ground | B11 to chassis | <10 ohm (not 0) |

These pins provide operating voltage to the internal microprocessor and complete the electrical circuit back to the chassis.
