Bosch Introduces The HDS 200 Heavy-Duty Scan Tool In North America
To better assist technicians in diagnosis and repair, the tool displays and graphs live data from SAE standard MIDS/PIDS along with on-screen definitions of diagnostic trouble codes and is HD-OBD compatible.
Diagnosing Pulse-Width Modulated PWM Fuel Pumps
Just this summer, I experienced a situation in which the fuel pump had been replaced four different times on a single vehicle with no result because the various repair shops attempting to repair the vehicle didn’t understand how to diagnose a pulse-modulated fuel delivery system. Here are five things you should know about diagnosing them.

Scan Tools: The Changing Field of Diagnostics
These past two months, I have been trying out a lot of new scan tools while trying to get better with my scope. I am quickly realizing how fast things are changing with tools, vehicles and diagnostics. When I started in this industry, the most advanced tool was a “brick” with a tiny monochromatic display, and the scope was the size of two large filing cabinets.
Aftermarket TPMS Sensors and Scan Tools
The aftermarket has grown rapidly to accommodate all the high-production road vehicles with various TPMS sensors, hardware kits and quick service scan tools with features and software to service any TPMS system.
Volumetric Efficiency Diagnostics
A few years ago, I obtained an OBDII scan tool/dynamometer simulation/calculation program that can graph volumetric efficiency (VE) over rpms. Using real world vehicles, and no useful instructions, I devised a test sequence that allows a technician to see things another way. What is Volumetric Efficiency? Let’s keep this simple to start. An engine is
