| Pin Function | Signal Type | Testing Procedure | | :--- | :--- | :--- | | | Hall Effect / Inductive | Check for 5V reference or AC pulse during cranking. | | Throttle Position (TPS) | Variable Resistor | Check 5V reference and signal ground. Signal voltage should sweep smoothly 0.5V–4.5V. | | Intake Air Temp (IAT) | Thermistor | Resistance changes with temp. High resistance = Cold. | | Engine Coolant Temp (ECT) | Thermistor | Similar to IAT. Verify resistance against temp chart. | | Map Sensor | Analog Voltage | 5V Reference, Ground, and Signal. Signal changes with manifold vacuum. |

Programming often requires specific connections to BOOT and CNF1 pins using specialized tools like ECUTools or cables like the F32GN037C. Sensor and Actuator Pin Assignments

Instead of saving 15 different blurry JPEGs, use this master table. Print it and tape it to your workbench.

Uses an ST10 processor with internal flash. This version often requires moving a 104 resistor

The is a widely used Engine Control Unit (ECU) found in various European and Asian vehicles, most notably within the Lada, Hyundai, and Kia lineups. Understanding its pinout is essential for diagnostic troubleshooting, performance tuning, or "on the bench" programming. Technical Overview

Use Pin 27 as your test ground when back-probing sensors. If you use Pin 11, you will read ~0.2v offset due to injector noise.
