Symptom Related Diagnostic Procedures

Symptom Troubleshooting Chart:

CAUTION:
- Before removing and installing the GEM/CTM or its connectors, disconnect the battery. Failure to follow this caution will result in the GEM/CTM storing many erroneous DTCs and may result in the GEM/CTM exhibiting erratic operation after installation.
- Be careful when probing the I/P fuse panel, engine compartment 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 electrical charges. If exposed to these charges, damage may result.

NOTE:
- If Continuous DTCs are recorded and the symptom is not present when performing the diagnostic tests, an intermittent concern may be the cause. Always check for loose connections and corroded terminals.
- Complete the entire diagnostic test related to the symptom before replacing the GEM/CTM.
