Intermittent Diagnosis Procedure

1. Clear DTCs & Reconnect Components
   
   Remove breakout box. Reinstall any components previously removed. Clear all DTCs. Turn ignition on with engine off. ABS warning light should come on for 3 seconds, then go out. If ABS warning light comes on for 3 seconds, then goes out, go to step 3). If ABS warning light stays on, go to next step.
2. Connector/Terminal Check
   
   Check all affected component connectors for bent or backed out terminals, damaged connector terminal locks, and damaged connector wedges. Also check intermediate connectors. Repair or replace components as necessary and go to step 5). If component connectors are okay, go to next step.
3. Wiggle Test
   
   Turn ignition on. While observing ABS warning light, wiggle affected or suspect circuit from one end of circuit to other. If ABS warning light comes on, turn ignition off and go to step 5). If ABS warning light does not come on, go to next step.
4. Verify All Circuits Have Been Tested
   
   Ensure all affected circuits related to trouble code have been tested. If all affected circuits have been tested, turn ignition off and go to step 6). If all affected circuits have not been tested, repeat step 3).
5. Retrieve DTCs
   
   Turn ignition off. Retrieve DTCs. If trouble code retrieved is different than code being serviced, perform appropriate circuit test. See CIRCUIT TESTS  . If trouble code retrieved is not different than code being serviced, repair wire or terminal as necessary. Go to next step.
6. Verification
   
   Ensure following items have been performed:
   • Verify SYSTEM PRECHECKS have been performed and a trouble code retrieved.
   • Verify all steps of CIRCUIT TEST have been performed.
   • Verify all steps of SYMPTOM TESTS have been performed.

If all steps have been performed, return to appropriate circuit test. See CIRCUIT TESTS  . If all steps have not been performed, return to appropriate test procedure and continue testing.
