CONTINUITY TEST
Inspect connector pins/sockets for damage,
corrosion, and serviceability. Check that
connector pins are not pushed back and
are capable of making good contact.
NOTE
Use care when testing electrical connectors.
Do not damage connector pins or sockets
with multimeter probes. Failure to comply
may result in damage to equipment.
Loose or dirty connectors may cause
intermittent loss of power to transmission
ECU and diagnostic codes to be logged.
Ensure that all connectors are clean and tight
before performing troubleshooting. Failure to
comply may result in incorrect test results.
CAUTION
Wear appropriate eye protection when working
under vehicle due to the possibility of falling
debris. Failure to comply may result in injury
to personnel.
WARNING
Ensure exhaust system is cool before performing
troubleshooting. Failure to comply may result in
injury to personnel.
