System too
Description The fuel trim is related to the feedback compensation value, not to the basic injection time. The fuel trim consists of both the short-term and the long-term fuel trims. The short-term fuel trim is fuel compensation that is used to constantly maintain the air-fuel ratio at ...

Problem symptoms table
Hint: Use the table below to help determine the cause of the problem symptom. The potential causes of the symptoms are listed in order of probability in the "suspected area" column of the table. Check each symptom by checking the suspected areas in the order they are listed. Re ...

Low battery positive voltage
Description When there is an abnormality in the power supply circuit of the brake actuator (skid control ecu), the skid control ecu sets a dtc and the operation is prohibited by the fail-safe function. This dtc is set when the voltage supplied to terminal ig1 is outside the dtc detection ...
