Symptom Troubleshooting Chart
CAUTION:
-
Before removing and installing the GEM or its connectors, disconnect the battery. Failure to follow this caution will result in the GEM storing
many erroneous DTCs and may result in the GEM 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.
