Pinpoint Tests
CAUTION:
-
Diagnosis by substitution from a donor vehicle is NOT acceptable. Each vehicle is configured to it's own vehicle identification data (VID) block,
and substitution of control modules may not only not confirm a fault, but may cause faults in the vehicle being tested and/or the donor vehicle.
Failure to follow this instruction may result in damage to the vehicle.
-
Electronic modules are sensitive to static electrical charges. If exposed to these charges, damage may result. Failure to follow this instruction may
result in damage to the vehicle.
-
When probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit, part number 3548-1358-00. Failure to
follow this instruction may result in damage to the vehicle.
NOTE:
-
When performing voltage or resistance tests, always use a digital multimeter (DMM) accurate to 3 decimal places, and with an up-to-date
