Toyota Hilux 3.0 SVR

Hello people! I have a generic scanner in the workshop and with him I can not turn off the witness light of the diesel filter. Change the filter and clean the base well, but the light is still on. Can you guide me what can I do to prescribe the light? They told me that disconnecting the sensor in contact on and bolver aconect it went out but did not have positive results. Toyota Hilux 3.0 SVR
