Pinpoint Test Notes

CAUTION:
^ Before removing and installing the GEM/CTM or its connectors, disconnect the battery. Failure to follow this caution will result in GEM/CTM storing many erroneous DTCs and it may exhibit erratic operation after installation.
^ Be careful when probing the Battery Junction Box (BJB), Central Junction Box (CJB) 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 citarges, damage may result.

NOTE:
^ If continuous 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.
^ Complete the entire pinpoint test related to the symptom before replacing the GEM/CTM.
