  1. Turn the ignition to OFF.
  2. Disconnect the transmission connector B90.
  3. Measure the resistance as follows:
    • Between connector B90 terminals 4 and 9.
    • Between connector B90 terminal 4 and body ground.
    • Between connector B90 terminal 9 and body ground.
Is the resistance measured within specified value?		 Between terminals 4 and 9 = 5 to 5.6 Ohms
Between terminal 4 and body ground = 10 Kohms or higher
Between terminal 9 and body ground = 10 Kohms or higher		 Go to Step 4  Go to Step 5

  1. Connect the transmission connector B90.
  2. Disconnect the ECM connector C19.
  3. Measure the resistance as follows:
    • Between connector C19 terminals 57 and terminal 77.
    • Between connector C19 terminal 57 and body ground.
    • Between connector C19 terminal 77 and body ground.
Is the resistance measured within specified value?		 Between C19 terminals 57 and 77 = 5 to 5.6 Ohms
Between C19 terminal 57 and body ground = 10 Kohms or higher
Between C19 terminal 77 and body ground = 10 Kohms or higher		 Go to Step 9  Go to Step 6

  1. Remove the shift solenoid SLU.
  2. Measure the resistance between terminals 1 and 2.
  3. Connect the positive lead with a 21 watt bulb to terminal 2 and the negative lead to terminal 1 of the solenoid valve connector, then check the movement of the valve.
Is the resistance measured within the specified range and can an operating sound be heard when connecting the positive and negative leads?		 5 to 5.6 Ohms Go to Step 7  Go to Step 8
