Once the vehicle is moving, you might hear a whine coming from the center of the vehicle.
A 5-volt reference flows through a sensor with a resistance that varies according to changes in temp., pressure or position.
Using new TPMS tools, you can have several options to replace and reprogram a sensor.
These are all the steps you’ll need to pinpoint fault issues in TPMS for 2009-2016 Audi A8 vehicles.
The two most important parameters to look at are the desired boost pressure and actual boost pressure during a test drive.
The measurement of voltage is like the speed of highway traffic – when loads are light, the voltage does not drop.
Double-check as you go that the steps are done correctly. There are no shortcuts to the relearn process.
Serial data buses help to eliminate multiple sensors and wiring. One sensor can share information with multiple modules without having to connect directly to the multiple modules.
The secret to being able to capture and analyze secondary ignition waveforms is understanding what is happening in the coil and at the spark plug and how the scope measures and graphs the voltages and ignition event.
Some vehicles with rear-wheel drive and may exhibit a driveline clunk or bump that occurs as the vehicle starts to move forward following a stop. This condition may be caused by the slip yoke not sliding smoothly on the output shaft splines. Action: Lubricate the slip yoke with a PTFE lubricant or a lubricant specified
ADS 4.0 introduces many new and improved features, including faster scanning capabilities with Quick-Scan, enhanced European vehicle coverage, access to FCA Secure Gateway (SGW) vehicles and continued free access to Repair-Source.
Wiring diagrams and the correct probes are ways technicians can avoid scarring a vehicle for life.
