CAUTION
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.
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.
NOTE
Inspect connector pins/sockets for damage,
corrosion, and serviceability. Check that
connector pins are not pushed back and
are capable of making good contact.
