Some FAQ and the reasons why diagnostic OBD2 scanner is necessary

What does a "MIL", "Check engine" or "Service Engine Soon" mean?

All three have the same meaning. These warning device inform drivers there night be something wrong with the vehicle’s engine or emission system and it should be noticed as the soonest possible in order to avoid any further damages, with the exception of intermittent warning. People should consider seriously the potential damages if the fault shows up on the display but they ignored it for too long. Form a habit of always paying attention to all the equipment every time you drive because you might notice early the dangerous symptoms, especially the coolant temperature. If the "Check engine" appears constantly during driving, the first thing to do is to figure out what those gauges are. In case they do not give a "normal reading", stop it immediately and have further investigation.

What does CAN mean and what are its functions?

CAN or Controlled Area Network was first invented in early 90’s and have developed greatly since then. The combination between CAN system and OBD system prove tremendous benefits as improving the safety and advantageous features being included into the whole system. The CAN combines and helps different separate modules work together smoothly through network communication.

If the "Check engine" lights ON while driving what are the procedures?

There are two types of fault lighting on this warning gauge.

• The worst one is the constant lighting and it means that you should stop to the side and turn off the engine immediately. Before that go checking if the instrumentation gauges are reading out of range and any other warning signs come along. This may become more clear when analysing the fault and do some repairs later. Never keep driving in this kind of situation.
• The less serious one is the discontinuous lighting. It allow you to have short-driving distances till all the checking and repairing are done. nonetheless, lengthen the time can cause further and even more serious problems which can lead to continuous illumination.

Will the light go Off if it is ignored and driving is continued?

This is wrong way of thinking and at the end, it causes more harm than good. The only chance that the light does go OFF is in discontinuous mode but its does not mean the fault are eliminated completely. And, if the fault is real, it will reoccur and exist for a long time. To make sure the situation is alright, have your car checked through diagnostic OBD2 scanner to see what going on.
