OBD II Diagnostics:Tips And Tricks to Make the Process Easier
The Malfunction Indicator Lamp (MIL) can be a golden light of opportunity for your shop. If the light comes on, it means the Onboard Diagnostics II system (OBD II) has detected an emissions-related problem. OBD II is designed to turn on the MIL if a problem occurs that may cause emissions to exceed federal limits
Muscling in on Restoration & Performance Work: Part 1
As automotive technology continues to become more complex with each new model year, you may be longing for the “good ol’ days” when engines had carburetors and distributors but no sensors, fuel injectors or computers. Most driveability problems were fairly simple to diagnose and only required a trained ear and a few basic tools. Alas,
Understanding Operating Strategies
As driveability technicians, we’ve been taught to solve diagnostic problems by gathering and analyzing data. Data usually comes in three basic forms, the first of which is sensory data that we can see, hear, smell or feel. The second form is measured values gathered by using test equipment like lab scopes and multimeters. The third
Hot Heads for Cool Cars
The numbers are not huge yet, but there is a growing demand for high-performance cylinder head work and other engine modifications on a variety of sport compact cars. The most popular nameplates are imports such as Honda, Acura and Mitsubishi, but coming on fast are Nissan, Toyota, Mazda, Subaru and Volkswagen – plus domestic models
Engine Series: Proper Maintenance Can Extend an Odyssey
We all know that some vehicle owners don’t adhere to preventative maintenance schedules for their vehicles. So when a customer’s vehicle is in for a major problem or service, take advantage of in-depth system inspections. It may be one of the few times that you get to check the vehicle for severely worn parts. Although
Matching Your Techs with the Right Job
Just a single decade ago, many industry experts speculated that 80% of the workflow passing through an independent repair shop would involve some type of high-level diagnostic process. Today, it’s obvious that, with the infusion of electronic operating systems, high-level diagnostics is now approaching that level of total workflow. Nevertheless, many others continue to ridicule
Understanding Today’s Multi-Coil Ignition Systems
Distributorless Ignition Systems (DIS) have been around for more than two decades, but in recent years the trend has been to multi-coil systems such as Coil On Plug (COP) or Coil Per Cylinder (CPC) ignition systems, and Coil Near Plug (CNP) ignition systems. COP systems have become the hot setup for a number of packaging,
Secondary Ignition System Maintenance
As one might expect, the introduction of low-maintenance ignition systems has changed how we sell and service secondary ignition system parts for import vehicles. Most import nameplates have, for example, replaced conventional distributor ignition systems with distributorless or coil-on-plug (COP) ignitions in order to reduce the number of wearing parts in the secondary or high-voltage
