System Checker Harnesses (07HAZ-PJ7010A and 07HAZ-PJ7000A ) and Test Harness (07GMJ-ML80100 ) are needed to test harness and specific components. These function as a breakout box to access pin voltage signals while component is either in or out of circuit. To reset ECU and clear codes from memory, remove 10-amp "EFI/ECU" fuse in the under-hood relay box for 10 seconds.
