Tech Update: Scan Tools & Code Readers
One thing you can always count on in the automotive repair business is that diagnostic equipment is constantly changing. It must to keep pace with changing automotive technology. So the latest crop of scan tools and code readers have more features, more capabilities and give you more bang for your buck than ever before. There’s
UEi Automotive’s ADL7103 Dual Channel Scope Diagnoses Multitude of Automotive Faults
The ADL7103 can quickly diagnose automotive faults from making voltage checks, reading codes, resetting malfunction indicator lamps to viewing signal waveforms. The ADL7103’s combination of features also includes a ….
Tech Tip: Are You Unnecessarily Replacing Starters and Alternators?
How many starters and alternators are replaced unnecessarily every year because of misdiagnosis? Nobody knows for sure, but suppliers of both new and remanufactured rotating electrical parts tell us more than half of their warranty returns have "no fault found" when the parts are examined. Many of these returns are from DIYers who lack diagnostic know-how, but some are from professional technicians who apparently lack the ….
Tech Tip: Diagnosing a Cylinder that is Misfiring
A flashing Check Engine light and a P0301 to P0312 diagnostic trouble code are sure-fire indicators that one or more cylinders are misfiring. Occasional misfires may pass unnoticed, but a steady misfire is hard to miss. The engine usually feels rough, lacks power and uses more gas than usual. Sometimes a misfire may feel like a vibration. A misfire also will cause a huge increase in hydrocarbon (HC) emissions out the tailpipe, which can cause a vehicle to fail an emissions test.
UEi Automotive Introduces the ADL7103 Dual Channel Scope
The ADL7103 can quickly diagnose automotive faults from making voltage checks, reading codes, resetting malfunction indicator lamps to viewing signal waveforms. The ADL7103’s combination of features also includes a library of known good patterns with preset test parameters for common automotive signals. Each test can be fine tuned to view any portion of the signal for further analysis.
Is There Enough Pressure? Fuel Injection Diagnosis & Service
One of the first questions that should always be asked — and answered — when diagnosing a fuel-related complaint on a fuel injected engine is, “What is the fuel pressure?” All too often, technicians assume fuel pressure is “good” without actually measuring it with a gauge. If the engine runs, they assume the injectors are
Tech Tip: Diagnosing Starting/Charging Systems
How many starters and alternators are replaced unnecessarily every year because of misdiagnosis? Nobody knows for sure, but suppliers of both new and remanufactured rotating electrical parts tell us more than half of their warranty returns have "no fault found" when the parts are examined. Many of these returns are from DIYers who lack diagnostic know-how, but some are from professional technicians who apparently lack the same skills.
News Update: NAPA Chassis Trains, Certifies Technicians
Participants in a four-day NAPA Chassis training class were provided with tips and techniques from NATEF-certified instructors to identify and solve problems while diagnosing and repairing late-model chassis and suspension systems. Held recently at NAPA’s training center, the clinic taught timesaving repair procedures, giving these techs the ability to be more proficient on newer vehicles.
Starting/Charging System Diagnosis: Fixing Faults the First Time Eliminates Comebacks & Returns

Tech Tip: Replacing Wheel Bearing Hubs Equipped with Wheel Speed Sensors
When engineers came up with the idea of putting the wheel speed sensor (WSS) and tone ring inside a sealed wheel bearing hub assembly, it seemed like a great idea. The sealed environment would help protect the sensor and make it less vulnerable to damage or contamination from the outside world.
