#Solenoid Test
  • Use the Solenoid Test feature to verify the TCM's ability to energize individual solenoids.
  • This feature does not test the electrical condition of a solenoid.
  • The test verifies the TCM is correctly sending commands to energize/ de-energize each individual solenoid.
  • The test does not verify that vehicle wiring or solenoids are operating properly.
  • Perform this test with the Ignition ON, Engine OFF and the transmission in Neutral.
  • Consequently: depending on the particular test, the user may need to use a voltmeter to complement the purpose of this feature.
