Set your DMM to DC Volts. Probe the Terminal 30 and Terminal 15 pins relative to the engine ground. You must see battery voltage (>12.0V). Probe the ECU ground pins relative to the battery negative post; resistance should be less than 0.5 Ohms.

The Bosch Motronic ECU (Engine Control Unit) is a widely used engine management system in various vehicles. Understanding the pinout of the ECU is crucial for tuning, troubleshooting, and modifying the engine. In this blog post, we'll provide a detailed overview of the Bosch Motronic ECU pinout, including the pin configuration, functions, and wiring diagrams. Analog or digital signals coming from the Crankshaft

Low-side drivers that pulse the negative/ground side of the injector circuits to meter fuel.

How to identify pins on a specific Motronic ECU Measure resistance across sensor pins

Before looking at pins, understand the system. Motronic was revolutionary because it combined and ignition control (Electronic) into a single ECU. Unlike older systems that used separate boxes for fuel and spark, Motronic synchronizes both.
