Pinpoint Test Notes

CAUTION:
^ Disconnect the battery before removing and installing the Generic Electronic Module (GEM) or its connectors. Failure to follow this caution will result in the GEM storing many erroneous DTCs and it may exhibit erratic operation after installation.
^ Be careful when probing the fuse junction box, power distribution 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.
