Technology Corner: Artificial Intelligence
What is Artificial Intelligence? Simply put, it is the development of computer systems able to perform tasks that normally require human intelligence, such as visual perception, speech recognition and decision-making.
Marketing To Everybody: Concentrate On The Core, Not Stereotypes
No one likes to be stereotyped. Too often marketing “professionals” make assumptions about age or gender groups because it is easier than dealing with individuals. Stereotypes can cloud your judgment when it comes to your shop and how you market to new customers to hopefully expand your business.
A/C Oil Service: Achieving Balance
HVAC systems often fail because the air conditioning compressor fails. Not following the proper service procedures or compressor oil recommendations could be factors that contribute to premature compressor failure.
Fuel Pump Codes And Control: Keeping Pressure In The Zone
Since the fuel pump module needs information for various sensors, it usually communicates on a serial data bus. If modules are not communicating, the fuel pump can’t be adequately controlled. The key to investigating these problems is to communicate with different modules to see what data PIDs are present and which ones are missing.
Communication Breakdown: Diagnosing Networks
If serial data buses did not exist, a wiring harness would have to be five times its normal size and use twice as many sensors to deliver the same level of functionality and safety we see in the modern vehicle. For example, take a brake pedal sensor. On a modern vehicle, the position of the brake pedal is used by the shift interlock, ABS, cruise control, traction control, brake lights and electric parking brake. If each system required its own switch and wiring, the complexity of the wiring harness and switches would be a diagnostic nightmare.
10 Tips For Serpentine Belt System Inspection And Service
The serpentine belt is part of a system and is not the only component susceptible to wear. The tensioner, idler pulley and, on some vehicles, the decoupler pulley all wear over time and need periodic inspection and replacement. If you are replacing just the belt without looking at the other components, you could be sending a new belt to a premature death.
Alternator Ripple Testing: The Ghost In The Machine
Before computers and networks in vehicles, an alternator that was producing AC voltage or ripple through the electrical system would cause flickering lights and maybe an ignition problem. Today, excessive ripple voltage can cause communication issues with networks and communication DTCs in multiple modules.
Subaru Tech Tip: Washer Fluid Level Sensor Diagnostics
The purpose of this Service Bulletin is to explain the inspection, diagnosis and replacement procedures for the washer fluid level sensor.
Acura Tech Tip: Tire Fill Assist Activation
The Acura Tire Fill Assist system on some Acura model is designed to help drivers set the correct tire pressure by flashing lights and horn. But, it can activate when you are servicing the vehicle.
Dodge Tech Tip: Oxygen Sensor Codes
If the vehicle has any O2 sensor-related DTCs stored, pending or active, perform the repair procedure.
What Is 0W16 Oils And SN-Plus Certification? Can 0W20 Be Used Instead Of 0W16?
You may have noticed that some Toyota and Honda four-cylinder vehicles require SAE viscosity 0W16 oil. The oils really stand out on a shelf because the last number is strange because it does not end in a five or zero. You may have noticed it in the catalog pages or shelves of your oil supplier. 0W16 oil has been around for almost two decades in Japan. It is an oil that is designed to increase engine efficiency and reduce engine warmup time.
Getting Plugged In
Have you ever plugged in the scan tool into the Diagnostic Communication Link (DCL) and saw a no communication message? Is it a scan tool issue or something going on with the circuits for the 16 pins in the connector?
