July 1: So it begins. Don't worry, this is not in the correct legal jurisdiction!

Clearing Continuous Memory Codes

1. Perform Key ON Engine OFF (KOEO) self test.
2. When service codes begin to be displayed, deactivate self test as follows:
a. STAR tester, position center button in up position.
b. Analog volt/ohmmeter, remove jumper wire from self-test input connector and signal return pin of the self-test connector.
c. Check engine light, remove jumper wire from self-test input connector and signal return pin of the self-test connector.
3. Continuous codes should now be erased.
