  1. Perform KEY ON/ENGINE OFF SELF-TEST. When the first service code appears, exit SELF-TEST program by disconnecting STAR tester or by removing jumper wire from Self-Test Input (STI) pigtail. Exiting QUICK TEST  in this manner will clear all codes stored in continuous memory.
  2. Repeat KEY ON/ENGINE OFF SELF-TEST. If code output is 11-10-11, go to CONTINUOUS MEMORY CODES TO BE TESTED. If code output is not correct, check Self-Test Input (STI) circuit for short to ground. Repair short and repeat CLEARING CONTINUOUS MEMORY CODES step.
