PINPOINT TEST G195523p8



Pinpoint Tests

CAUTION:
- Be careful when probing the fuse junction panel, 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 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.
