This function of the power management system uses several modules to decide when the engine needs to stop and start.
When trying to resolve a complaint, code or no-start/no-crank condition on a stop/start vehicle, it is essential to know how the system operates. The problem may not have a complicated reason – something simple may cause the stop/start system not to work.Â
The greatest obstacle to the advancement of stop/start technology is the driver’s and technician’s lack of trust in and knowledge of the technology. Many older drivers and technicians fear that stopping and starting the engine will cause a shorter life for the battery, starter and engine. But the real fear is that the engine will not start again at a green light.Â
Like any automatic transmission, the condition and level of fluid in a CVT unit will determine the performance.
Over time, the oil filter can collect enough contaminants to become restricted.
The key to servicing these systems is proper information and understanding precisely how these systems operate.
Every driver has a different threshold for a pull.
If the clutch gets too hot from excessive slippage or loading, the linings may burn, damaging the clutch.
Accuracy is important for sophisticated ADAS systems.
AWD is always engaged and with the ABS brake modulator, can perform like systems with limited-slip differentials.
The heat eventually burns out the blower motor resistor, and, in many cases, causes the electrical connector to melt.
