Step-by-Step Bench Connection Preparation
Check the ECU housing and connector for water entry, corrosion, bent terminals, impact damage or signs of previous opening.
Capture the Bosch number, OEM part number, barcodes and secondary labels without cropping them.
Match EDC17C59, TC1767, the vehicle group, supported operation and connection mode.
Determine whether the diagram shows the ECU terminal face, harness connector or wiring side.
Make every required connection with the external power supply switched off.
Attach CAN High, CAN Low and any protocol-specific service lines exactly as displayed.
Use a multimeter to check polarity, continuity and the absence of unintended short circuits.
Power the ECU only after completing all checks. Begin with electronic identification.
