ECM Damage
Engineers have devised two strategies that can be called the “immune system” for the electrical system.
Checking The Auxiliary Water Pump
A car or truck comes into the shop with a complaint of poor heater performance. The issue may be the auxiliary water pump.
It’s Got Spark!
Why can’t you trust some spark tests?
Diagnostic Strategies For Stop/Start Systems
This function of the power management system uses several modules to decide when the engine needs to stop and start.
CVT Transmission Service
Like any automatic transmission, the condition and level of fluid in a CVT unit will determine the performance.
Testing A/C Or Heater Blower Motor Circuits
The heat eventually burns out the blower motor resistor, and, in many cases, causes the electrical connector to melt.
Understanding Underhood Parts for Hybrids
Anything that can happen to an ICE in a standard vehicle can happen to an ICE in a hybrid.
Batteries For Stop/Start Systems
On all stop/start vehicles, the life and performance of the battery are measured by the vehicle in several ways.
Diagnostic Procedures For Stop/Start Systems
Stop/start technology is more than just a switch wired to the brake pedal and starter.
Topology and Your Scan Tool
Topology influences how you access the modules with your scan tool.
