Review on Enhance Diagnostics with the Power Probe OBD II Breakout Testing Box by Lild Zimmerly

. Being able to quickly view CAN activity and voltage is easy and gives me the ability to connect my scanner and oscilloscope to the DLC at the same time. I really like Power Probe products and this one did not disappoint. The design is well thought out and well made, very substantial weight and feel. The LED indicators are bright and easily visible in direct sunlight. The voltage readout is conveniently located on the tool and allows me to measure and monitor voltages on individual pins without an additional meter. If you own a GM vehicle and do the work yourself, you need this tool in your arsenal.
