Flashing, ADAS, Start-Stop – Systems Keep Evolving

This month, we take a dive into three critical areas of change related to the repair and maintenance of vehicle starting and charging systems: module reprogramming, ADAS system repair and recalibration, and Start-Stop systems. Each of these areas are evolving quickly and all have major impacts to the equipment needed…

Rapidly Changing Vehicle Systems – Challenge, Opportunity or Both?

“Every system on the vehicle has undergone a technological transformation – including the fundamental battery and charging system. The higher demands of “Start-Stop” technology, the advances in charging system strategies, and the introduction of new battery designs all require today’s shop owner and technician to be up-to-date on diagnostic and…

Troubleshooting 5V Reference Circuits

In modern vehicle design, 5-volt reference signals/circuits are a key aspect of vehicle command and control. As summarized by Gary Goms, the 5-volt reference signal typically “flows through a sensor containing a resistance that varies according to changes in temperature, pressure or position. Due to this variable resistance, the signal…

Diagnosing Manufacturer-Specific System Designs

Electrical system diagnosis and repair is tricky business to begin with. Parasitic drains, intermittent faults and inefficient/improper grounds are just a few of the ways technicians can get drawn down the wrong diagnostic rabbit hole. This was true even for vehicles from the turn of the millennium, when system design…

The Straight Skinny on Battery Service

When we do a survey article, we typically group them by content, gathering several resources related to a specific service challenge. This month’s article is a grouping of another sort. This month, we are featuring several resources that could be said to be grouped under the heading, “We love to…
