Vehicles have been through a succession of challenges, mainly in the emissions and safety departments. These developments are good news to each one of us – as reducing vehicle emissions will help us live a healthier, less polluted life. Safety features like air-bags, ABS and stability control all help minimize human error mistakes and in case of an accident the passengers are more likely to survive the accident. These are all controlled through electronic modules which need a Diagnostic OBD2 Scanner when a fault occurs.
The OBD II Software
The OBD II software (On-board Diagnostics 2) is the second generation or updated system. The first OBD system was used as necessity because of tougher Federal legislation in the US. Manufacturers started using emission devices to reduce the exhaust pollution level in their new vehicles. This ultimately lead the manufacturers to seek better solution systems available and so started moving onto electronically controlled systems for fuel to air mixes and ignition. Thus the OBD was created. This served a dual purpose as it also had an OBD plug for diagnostic purposes. The OBD system did vary from manufacturer to manufacturer as there was no regulatory board set up. As long as the emissions were within the safety parameters of the EPA (Environmental Protection Agency) they moved on to production, so there are very few set standards on the OBD system. The SAE (Society of Automotive Engineers) started working and changed all this with a set of common standards. A good example is the OBD plug which was standardized for all OBD systems. Test signals were also standardized so better maintenance could be achieved through a vaster range of professional mechanics other than the main dealer.
The OBD2 system is an upgraded version of the OBD system and it now integrates with more hardware and software systems than it did previously. CAN (Controlled Area Network) is one such system.
CAN system
This system started out through German manufacturer Mercedes Benz on their production cars in 1992. CAN was initially introduced to reduce the amount of wires in the vehicle’s wire harness thus reducing production costs and vehicle weight. The CAN system has expanded significantly throughout these years, with communication speeds increasing drastically and the addition of much more safety and comfort devices.
These particular systems need a special type of Diagnostic Scanner when faults emerge. Most Diagnostic OBD2 Scanners which do not accept the CAN involvement cannot be used to diagnose such systems with CAN integrated into the OBD2 software. Luckily though these scanners are becoming much more affordable now and with a little sacrifice anyone can purchase a Diagnostic OBD2 Scanner which accepts and also diagnoses the CAN system. The initial investment of these scanners will pay off immediately the first time they are used to repair a fault as diagnosing and repairs by professionals will cost a fortune. This system opens an opportunity for anyone willing to take on their vehicle’s repairs as the scanner removes most of the guess work and puts the professional experience in par to most knowledgeable Do-It-Yourself-ers.
