Bosch EDC17C11, C18, C19, C59 and ME17.9.5 (Opel, Vauxhall, Chevrolet, Saab, Suzuki): connection diagrams

The diagrams for the Bosch ECUs of the GM/Opel group and its derivatives, including the versions shared with Nissan, Renault and Saab and the ME17.9.5 petrol units also used by Suzuki.

Procedure

1. Pin down the designation from the label: EDC17C11 TC1766 (Nissan, Opel, Renault, Saab), EDC17C18 TC1766 (Opel), EDC17C19 TC1792 (Opel, Vauxhall, Saab), EDC17C59 TC1767 (Chevrolet, Opel), ME17.9.5 and M17.8.XX TC1767 (Opel, Suzuki).
2. Check the Tricore microcontroller on the board: the EDC17C19 is the only TC1792 of the group and does not share its diagram with the TC1766 units.
3. Open the manual page for the entry you identified and build the loom as per the drawing, respecting pin numbering and wire colours.
4. For the ME17.9.5 and the M17.8.XX TC1767 additionally use the "BSL connection" diagram given in the same section if you need to work in boot mode.
5. Power the ECU on the bench and check the voltage before connecting the AVDI.
6. Connect the AVDI and start the read from the software.
7. Save the original file you read out and keep it before performing any write.
