Diagnostic Tip: If the VC voltage reads below 4.0V, one of your shared engine sensors is likely shorted internally to ground, pulling down the entire reference circuit. Disconnect sensors one by one to see if the voltage recovers. Step 3: Checking Common-Rail Pressure Feedback Back-probe the pin while cranking the engine. At rest, voltage is typically around 0.5V to 1.0V.

Here is a "good write-up" regarding the diagram, functional pins, and technical notes.

Toyota uses different wiring colors depending on the market (Europe, Australia, South Africa, Thailand, Latin America). Colors in this guide are typical for a 2010–2015 Hilux, but always verify continuity to the sensor before cutting a wire. : Serial data link used to transmit diagnostic

Note: Pin numbers are always counted looking directly into the face of the wire-harness side connector, or matching the male pins on the ECU housing. Comprehensive 2KD-FTV ECU Pinout Breakdown

These pins ensure the ECU receives stable electrical current and a clean path back to the negative battery terminal.

The pinout revealed that the EDU relay (which powers the injectors) was not receiving the correct 12V signal from the main ECU to activate. The Fault Found Diagnostic Tip: If the VC voltage reads below 4
