The transmission internal mode switch connects electrically to the control solenoid valve assembly. Inspect the transmission internal mode switch, harness, connector and control solenoid assembly pins for metallic debris. Use a terminal test kit for any test that requires probing the control solenoid assembly harness connector or a component harness connector. The transmission internal mode switch can be damaged by currents exceeding 2 mA. Test the transmission internal mode switch for an open condition whenever a short to voltage condition is observed.
