4. Is resistance within specifications?
  YES : --> Go to 2 "Check signal circuit short inspection" procedure.
  
  NO : --> Check for open in harness. Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
Check signal circuit short inspection
1. Ignition "OFF".
2. Disconnect "A/T SOLENOID VALVE" connector and "PCM/TCM" connector.
3. Measure resistance between terminal "4" of the ATM SOLENOID VALVE harness and chassis ground.
