Pinpoint Test Notes

PINPOINT TESTS

CAUTION:
- Before removing and installing the SJB or its connectors, disconnect the battery. Refer to Battery. Failure to follow this caution will result in the SJB storing many erroneous DTCs, and it may exhibit erratic operation after installation.
- Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
- Electronic modules are sensitive to electrostatic discharges. If exposed to these charges, damage may result.

NOTE: 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 a new instrument cluster or SJB.
