When the terminals OP1 and E1 are connected, the circuit of the ECT sensor is grounded, fixing the coolant fan speed at approximately 1100 rpm.

  1. Start the engine without depressing the accelerator pedal.
  2.  
  3. Leave the engine running for several seconds.
  4.  
  5. Check that there is no foaming and emulsification of the fluid in the reservoir tank.
