Important Preliminary Checks Before Starting
Perform the Diagnostic System Check - Vehicle before using the Symptom Tables in order to verify that all of the following are true
Visual/Physical Inspection
- Inspect for aftermarket devices which could affect the operation of the system. Refer to «Checking Aftermarket Accessories»(/chevrolet/aveo/i-2006-2012/remont/body-electrical/#wiring-systems-and-power-management-inline-harness-connector-end-views-diagnosis__checking-aftermarket-accessories) .
- Inspect the easily accessible or visible system components for obvious damage or conditions which could cause the symptom.
Intermittent
Faulty electrical connections or wiring may be the cause of intermittent conditions. Refer to Testing for Intermittent Conditions and Poor Connections .
Symptom List
Refer to a symptom diagnostic procedure from the following list in order to diagnose the symptom
