Tech Feature: Detecting Misfires in OBD II Engines
With OBD II, there’s no missing misfires. Most engine control systems with OBD II monitor the speed of the crankshaft between cylinder firings to detect misfires. The powertrain control module (PCM) notes the relative position of the crankshaft via the crankshaft position sensor (CKP) each time a trigger pulse is sent to the ignition system.
Brake Safety Technology: Mercedes-Benz Brake Assist & Sensotronic Systems
One of the new safety technologies you’ll find in a growing number of European and Asian vehicles is Brake Assist (or BAS for Brake Assist System).

Tool Feature: Scan Tools and Software Updates
Though some vehicles have diagnostic modes that can show fault codes and other diagnostic information via the instrument panel, climate control system or driver information display, most simply turn on the check engine light or another warning light when a problem occurs. So without a scan tool, there’s no way to tell what the problem might be, let alone make an accurate diagnosis of which sensor or other component may need to be replaced.
Tech Feature: Making $ (Money) with Mode $06
Mode $06 is one of the nine diagnostic modes that is part of the OBD II on-board diagnostics system on all 1996 and newer vehicles.
What is Mode $06 and the other OBD II Modes?
OBD II modes are organized into nine categories, each of which is assigned a particular mode number preceded by a $ sign to symbolize the hexadecimal code it represents.
