Pinpoint Test Notes
CAUTION:^ Disconnect the battery before removing and installing the GEM or its connectors. Failure to do so will result in the GEM storing many erroneous Diagnostic Trouble Codes (DTCs) and exhibiting erratic operation after installation.
^ Be careful when probing the CJB, battery junction box or any connectors. Damage will result to the connector receptacle if the probe being used is too large.
^ Electronic modules are sensitive to static electrical charges. If exposed to these charges, damage may result
NOTE:
^ Refer to Vehicle/Diagrams for connector numbers stated in the pinpoint tests.
^ If continuous DTCs are recorded and the symptom is not present when carrying out the pinpoint tests, an intermittent concern may be the cause. Always check for loose connections and corroded terminals.
^ Complete the entire pinpoint test related to the symptom before installing the GEM.
