Therefore, when a commercially sold sensor or switch, etc. is installed, a wrong diagnosis is made, and the monitor comes On. Accordingly, if general commercially-available sensors or switches are installed, this will cause mistakes in diagnosis and the monitor to show an abnormality display. If a commercially-available electronic device such as a mobile phone, stereo or anti-theft device is inappropriately installed, an EMI may be emitted to the control system. As the result, false sensor information is generated causing the monitor to come on. When conducting a trouble diagnoses, either turn "OFF" the power for all commercially sold parts or remove them, and then check the failure again. Many OBD system checks go into the backup operation mode based on the instruction from the ECM which is given when the ECM detects a failure in the related systems or components. When the backup operation mode is activated, the output is reduced to protect the actual unit. Trouble diagnosis Basic knowledge of tools required • When performing the diagnostic procedure, lack of basic knowledge regarding this powertrain could result in an incorrect diagnosis or damage to the powertrain components. Do not attempt to diagnose a problem related to the powertrain without having the basic knowledge. A basic understanding of hand tools, such as the trouble diagnosis scan tools, is required to utilize the service manual effectively.
