DIAGNOSTIC
Diagnosing EVAP Systems
The latest regulations covering onboard evaporative emissions testing standards has resulted in Diagnostic Trouble Codes that are hard to diagnose.
We’ll outline the basics of how these later systems work and how to quickly and accurately troubleshoot faults associated with them. |

TECHNOLOGY
Converter Testing:
The CAT Is Out Of The Bag
This story will explore the catalytic converter issues and testing for a wide range of vehicles.
We’ll break down diagnosis into two parts: pre-OBD II vehicles and OBD compliant vehicles. Proper diagnosis requires repeatable diagnostic procedure that makes sure all systems are working correctly before pulling the trigger on a new catalyst. |

MANAGEMENT
Just For Starters
We’ll examine some common starter designs and offer testing techniques to assist in diagnosis of common starting concerns.
For example, starters have a tough job to begin with, and low voltage, whether from a weak battery or voltage drop due to bad cables and connections, will overheat a starter the same as if it were to stall out trying to spin a half-locked up engine.
