ADAS: Diagnosing False Activations and Warnings
This webinar is part of "AAPEX Repair Shop HQ Webinar Series: An 8-Part Webinar Series." Sponsored by AAPEX.
Advanced driver assistance systems (ADAS) can intervene with driver warnings or activation of the brakes and steering functions. Unfortunately, ADAS sometimes get it wrong and activates when there is no problem. The customer might be backing out of the garage or changing lanes on the freeway when the false warning or activation occurs. We will explore how to resolve customer complaints of false activation of automatic braking, lane blind spot detection systems.

Fuel systems can have many possible issues to diagnose. This video is sponsored by AP Emissions.
CC: In our last video, we looked at diagnostic tips related to Air in our traditional conceptual framework of Air, Fuel, and Spark. This video will look at Fuel
The first thing you want to do is check your fuel trims. An air fuel ratio of 14.7 Air to Fuel is ideal for most gasoline combustion engines when they are operating in normal closed loop operation. The further you are from stoichiometry, the more likely it is that you will trigger a catalyst inefficiency code. The vehicle works to maintain that ideal air fuel ratio by adjusting the amount time (injector pulse width) that injectors spray fuel into the combustion chamber. Pollution production is minimized when you’re at stoichiometry and the efficiency of the converter at reducing that pollution is maximized when you are near stoichiometry. Make sure the converter is getting the right air fuel mixture by looking at your total fuel trims and making sure the car is running close to stoichiometry.
If you notice that you’re running rich, you’ll want to check the following things:
If you notice that you’re running lean, here’s some things you can check:
