Just went out adjusting CO on the -14 ZE.
ignition off, press both TCS and RESET and keep holding them while turning the ignition on. After a few seconds the choise between
ECU or SCU (? Not paying attention to the second choice) shows up. release buttons and toggle your choice with TCS button.
Choose ECU and long press both TCS and RESET a few seconds and the display will show a smaller "diag". Another click on TCS will toggle to "co".
To enter CO, hold both TCS and RESET buttons for a few seconds and the CO 1 should show up (witch would be cylinder 1).
To enter long press both buttons and then chose value with TCS for up and RESET for down. when done a fast click on both buttons
will take you back to the CO 1..
Click TCS button to move on to CO 2 and repeat the above. When done turn off ignition.
This worked for me though it might be altenative ways
Greetings!
