Reversing polarity or applying 12V to a 5V sensor rail can permanently fry the internal EPROM.
The is a cornerstone of late 90s and early 2000s automotive engineering, famously powering high-performance Mercedes-Benz engines like the M112 V6 and M113 V8. Whether you are performing a diagnostic repair, an IMMO OFF procedure, or bench-flashing for performance, having a verified pinout is critical to avoid damaging these sensitive control modules.

The Bosch ME2.0 is a legacy engine control unit (ECU) primarily found in vehicles from the late 1990s and early 2000s, such as the W210 (E-Class), W202 (C-Class), and W163 (ML-Class). This unit is frequently accessed for bench testing, immobilizer (IMMO) off procedures, and basic tuning. Critical Connection Overview
For diagnostics and tuning, the communication lines are the most sought-after pins. Whether you are performing a diagnostic repair, an
