• Ignition off
• Connect the breakout box to the control module connector (transmission side).

  Check solenoid SL by measuring the resistance between terminals #A51 (#A51) and #A53 (#A53).

  When the transmission is cold (20°C), the resistance must be 10-11 Ω. When the transmission is at operating temperature (150°C), the resistance must not exceed 16 Ω.
