| Pin | Signal | Protocol | |-----|--------|----------| | T121/43 | K-line (Tx/Rx) | ISO 9141 (K-Line diagnostic) | | T121/46 | CAN-H (if equipped) | 500 kbit/s | | T121/47 | CAN-L (if equipped) | 500 kbit/s |
Key features:
Some CAN interfaces require a 120-ohm resistor between CAN High and CAN Low if the ECU is removed from the vehicle network. me7.4.5 pinout
For deep recovery or full cloning, you may need to put the ECU into . This typically involves grounding a specific point on the PCB (printed circuit board) while powering up the unit.
This guide provides a comprehensive look at the ME7.4.5 pinout, focusing on the connections needed for power, ground, and communication. Understanding the ME7.4.5 Connector Layout | Pin | Signal | Protocol | |-----|--------|----------|
To read/write the ME7.4.5 via (bench tuning), you need:
