Tips From A Tech: Getting Ready with Readiness Monitors
Setting readiness monitors can be a frustrating task. Here’s how to ensure an accurate repair.
VIDEO: The Battery Replacement Step You Always Forget
Battery replacement is one of the most common repairs performed by a shop, but some late-model vehicles require more than just attaching the cables and hold-downs.
VIDEO: Measuring Dwell In The Ignition System
A coil takes a finite amount of time to build up this charge. This is the dwell time, normally defined as the camshaft’s degree of rotation, during which the voltage flows through and charges the primary side of the coil.
Reflashing And Reprogramming For Newbies
The choice to reflash is the hardest because there is no one solution or single path to follow.
Solving Electronic Control Problems In Today’s Automatic Transmissions
Troubleshooting an automatic transmission can be one of the most intimidating diagnostic procedures a shop faces today.
Catalytic Converters: Efficiency Code Diagnostics
Understanding catalytic converter efficiency codes can be a long diagnostic road that can either lead to a happy customer or an expensive comeback.
Undercar Reflash: Stop Waiting, Wondering
At last count, more than 800 TSBs have been issued concerning reflashing or reprogramming over the past five years.
Coil On Plug Ignition: The Wired Differences
For late-model vehicles, the norm is one ignition coil per cylinder, commonly known as coil on plug. The task of providing voltage potential to each spark plug is performed so reliably that it’s easy to take for granted.
The Complicated Truth Of Alternator Testing Diagnostics
One test is not enough if you are diagnosing a charging system problem. All too often, the alternator is condemned as the source of the problem if only battery voltage is present with the engine running.
Understanding ABS Modulator Problems
Mechanical issues with the ABS modulator or hydraulic control units (HCU), are rare, but they can happen. With more vehicles on the roads having older ABS systems that have not seen proper brake fluid maintenance, mechanical issues are becoming more common.
