Continuous Self-Test Procedures

  1. Codes shown in this test are intermittent service codes. Unless instructed otherwise, DO NOT  disconnect any sensor with ignition turned ON as this may cause a service code to be stored.
  2. Verify that all previous Self-Test procedures indicated a pass (Code 11). If any On De,and code is displayed during this test, repair it first, as some hard failures will set a code in Continuous Self-Test.
  3. Perform key ON/Engine OFF Self-Test. When the first service code is appears, exit Self-Test program by disconnecting STAR tester or by removing jumper wire from Self-Test input. Exiting Self-Test in this manner will clear all codes stored in continuous memory.
  4. Repeat Key ON-Engine OFF Self-Test. If code output is not 11-10-11, check Self-Test Input (STI) for short to ground. Repair short and repeat Key ON/Engine OFf Self-Test. If code output is 11-10-11, go to next step.
  5. Check list of Continuous/Memory codes that were recorded in Key ON/Engine OFF (KOEO) and Key ON/Engine Running (KOER) Self-Tests. Disregard any codes that have already been repaired. To confirm remaining codes, perform Continuous Monitor (Wiggle) Test.
