Precautions
1. Engine parts are extremely hot straight after a drive, so cool them down sufficiently.
2. Diagnostic codes (self-diagnosis codes) are recorded on the ECU memory. Check the contents of the memory stored on ECU using a scan tool before starting an inspection on a sensor.
3. Make sure to disconnect battery terminals to prevent damages on electronic parts such as sensors or a fire.
4. High voltage at injector harnesses or electromagnetic valves can cause an electric shock. Make sure to turn the starter switch to “OFF” and pull out the key when carrying out a service.
