• Ignition off.
• Transmission connector A disconnected.

  Check solenoid S1 by measuring the resistance between transmission connector #21 and the transmission housing. The ohmmeter should read 12-18 Ω(at 20◦C).

  Other information: 

  • To disconnect transmission connector A, see Connectors, transmission, disconnecting/connecting .
  • For information about signals, see Signal description. Transmission control module (TCM) .
