  3. CHECK CRANKSHAFT PULLEY REVOLUTION (P POSITION) 
    1. Check that the shift lever is in P.
    2. Lift up the vehicle.
    3. Turn the crankshaft pulley using hand tools to check if the crankshaft can rotate smoothly.
      WARNING:

      Do not turn the power switch on (READY) while performing this inspection. Be sure to turn the power switch off before performing this inspection, to prevent the engine from starting.

      NOTE:

      Engine compression causes resistance when turning the crankshaft pulley. Check if the crankshaft rotates smoothly (or if it is locked) by manually applying sufficient torque to turn the crankshaft pulley. The torque required to turn the crankshaft pulley should be the same as for a known good vehicle of the same type.

      OK

      The crankshaft rotates smoothly.

    4. Lower the vehicle.
