Since model year 2003, a growing number of domestic and import vehicles have been built with a new onboard communications protocol called CAN (Controller Area Network). CAN is essentially an engineering standard for how computers and modules talk to one another via the serial data bus in a vehicle’s wiring system. It’s a high speed
Checking the Basics Saves Time When Chasing Check Engine Codes
After 10-plus years of dealing with OBD II, it should be apparent that we are on a learning curve that probably has no end. Almost daily we have a VAG model come into the shop with a check engine light on, or a “state OBD II failure” form. Although we have the latest scanner software
Early front-wheel-drive wheel bearing service was difficult and time intensive. The most common arrangement was a pair of tapered roller bearings similar to that of a rear-wheel-drive vehicle, but with a spacer between the bearings. Servicing this arrangement took time and often special tools. Of course, an axle shaft went through the bearings and spacer.
Keeping a record of scheduled maintenance and service repairs is probably the best selling feature when the time comes to trade or sell a vehicle. You know the type: They baby their car, and their friends and family want first dibs when they decide to sell it. In most cases, that level of upkeep is
In this scan tool diagnostics article, we take a look at Mode $06 functions which govern non-continuous monitors (EVAP, catalyst, EGR, etc.)
“CAN” is the new buzz word in automobile diagnostics. It stands for Controller Area Network and is a protocol for onboard diagnostics and scan tools. CAN is a high-speed data link that provides more information at a faster rate for better communication between onboard electronics and external diagnostic equipment. Many manufacturers have already started incorporating
