We know that the BS VI emission norms has been implemented from April 2020. All manufacturers jumped from carburetor to the fuel injection system except some manufacturers who have gone for the electronic carb. In every fuel injected motorbike, we can able to see provisions given for the OBD tool connection knows as Diagnostic Link Connector (DLC). This is also know as OBD socket and the tool which we plug and use in that is known as OBD tool. We think that this OBD feature is introduced only in the BS VI vehicles. But, this OBD has been implemented in the year 2010 itself.
Malfunction
In early fuel injected vehicles, we can identify the problems using this Malfunction Indicator Lamp (MIL) present in the instrument console. Fuel injection system consists of many sensors and actuators in it. If the vehicle is facing any starting trouble or any other electrical problems, it is more hard to find and rectify the problems. So what manufacturers have done is, they've given a indication lamp (MIL) in the instrument console which tells us the problem present in the vehicle. The problem can be identified with the help of short and long blinks of the MIL. Long blink is counted as 10s and short blink is counted is 1s. For example, assume the malfunction light is blinking as 5 long blink and 4 short blinks. Then the error code is 54. We can able to find out the problem by referring the manufacturer's error code list. Each and every problem is assigned with separate blink codes. We can able to find out the problem using this method easily and this method is used in the early days. As technology advanced, more and more sensors and actuators started to appear in the motorbikes. So, if there's more problem in the vehicle, it'll become more difficult to understand the problem using this error codes. At this situation, OBD tool comes handy.
Overview
This OBD system is present from the year 2010. From April 2020, new strict emission norms were listed out and so the manufacturers implemented the fuel injection system in their motorbikes. This is where all motorbikes started to come with OBD provision. Because as i said, presence of more technology and electrical system will become difficult to find the problem present in the motorbike. Electronic Control Unit or Engine Control Unit (ECU) is known as brain of the motorbike. Every parameters related to electronics such as sensors and actuators is controlled by the ECU. Everything is pre programmed in the ECU and it controls the ignition and injection. Different maps will be present inside the ECU. According to our throttle input, how much amount of fuel should be injected is decided by the ECU with the help of maps present in it. If anyone of the sensor or actuator in the system gets failed, mileage and other performance factors will be affected. For example, if anyone of the sensor is not functioning properly, the information will be stored in the ECU regarding that fault and the MIL starts to blink. When we connect the OBD tool in our vehicle, we can identify the problem easily. For this, manufacturers use separate software or handheld OBD tool. Here in aftermarket, we can able to get many OBD tools which we can use. This OBD tool comes with Bluetooth and Wi-Fi feature named as ELM 327. We have to install a separate application in our mobile for using this. After connecting, we can able to see the fault codes stored in the ECU and easily we can able to rectify the problem without wasting much time.
There are also several things that we can do with this OBD tool. We can able to monitor the real time data such ah coolant temperature, throttle position, battery voltage, oxygen present in the exhaust gas etc.. If anyone of this parameter is not working, we can check that also. Another one is clearing the error codes saved in the ECU. After rectifying the problem, sometimes the malfunction light continuously tends to blink. In that time, we can connect our OBD tool and we can able to clear that fault log or fault memory present in the ECU with the help of specific application or software. In cars, there are separate modules present for diagnosing such as powertrain module, ABS module etc.. But regarding motorbikes, we can able to find problems only about the engine. By using this OBD, mechanics can able to find and rectify the problems easily with the help of Diagnostic Trouble Code(DTC). Still in some places, MIL is used for finding out the trouble present in the vehicle. But this OBD allows us to find out the trouble quickly and rectify it as soon as possible.
The OBD method that we use today is called as OBD-2. First generation OBD was implemented in early 90s. But the problem in that is, every manufacturers used different socket and pins for their vehicle. So, the OBD-1 is not standardized across the manufacturers. After that, OBD-2 is implemented which we are using now have same kind of ports for all vehicles and gives same kind of data. In this OBD-2, features like real time data and different modules for different system has been implemented. Though manufacturers still use different DLC in their motorbike, we can use single OBD tool to connect any kind of motorbike. Only the connecting wire differs.
I hope now you have got the basic idea on this OBD. In future posts, will try to explain about the pins present in this OBD tool and their functions.
