  2. TERMINAL INSPECTION


    1. Disconnect the power take-off assembly connector and measure the voltage or resistance on the wire harness side.

      Tech Tips


      • Voltage/resistance cannot be measured with the connectors connected to the components (power take-off assembly, control unit relay assembly) as the connectors are watertight.

      • Control unit relay assembly outputs 20 to 28 V to the power take-off assembly for approximately 5 seconds when the power take-off indicator switch turned ON.
