Many vehicles are now being engineered with Stop-Start technology. Implementing automated stop-start technology in today’s vehicles is a cost-effective way to improve fuel economy and reduce emissions without affecting consumer acceptance. A Stop-Start system operates by cutting off the engine when the vehicle comes to a complete standstill, and automatically re-starts the engine when the driver releases the brake pedal. This operating strategy is often utilized in full hybrid-electric vehicles that have powerful electric systems, but is becoming more popular in non-hybrid vehicles that use traditional starter/battery configurations. We will cover manufactures using stop-start technology, dual battery and robust starter motor technologies, common components found on each system, diagnostic evaluation and repair methods and review important best service practices to handle working on vehicle's equipped with Stop-Start systems.
