Symptom Related Diagnostic Procedures

CAUTION:
- Be careful when probing the central junction box, battery junction box or any connectors. Damage will result to the connector receptacle if the probe or terminal being used is too large.
- Electronic modules are sensitive to static electrical charges. If exposed to these charges, damage may result.

NOTE:
- If continuous Diagnostic Trouble Codes (DTCs) are recorded and the symptom is not present when performing the pinpoint tests, an intermittent concern may be the cause. Always check for loose connections and corroded terminals.
- All module power and ground circuits must be checked prior to the replacement of the module. Return to the section that refered you here for power and ground circuit diagrams and testing procedures .
