TPMS Diagnostic Strategies – Eliminate The Obstacles

If you find a tire pressure sensor isn’t functioning, the natural assumption is the sensor is the problem – but is it?

One of the diagnostic mantras preached by service experts today is “test before you touch.” You should always use a TPMS tool to activate and check the response signal from each tire pressure sensor in each wheel before you do anything else. This will tell you:

• Whether or not each sensor is capable of generating a
signal; and

• If the sensor is generating a signal, whether or not the
pressure reading is accurate.

In this article from TechShop Magazine, you’ll learn more about today’s tire pressures and TPMS tools and procedures.

Ignition System Tests You Should (And Shouldn’t) Follow

Do your technicians use tests that might give inconclusive results or do damage to the coil or drivers inside a module?

One of the most basic circuits found on every gasoline-powered vehicle is the ignition coil. This transformer takes low-voltage, high-amperage current and changes it into high-voltage current. It has two windings that are not physically connected. What connects them is magnetism. The primary creates an electromagnetic field when system voltage is applied. When the power is turned off, the magnetic field collapses. The energy from the primary is transformed by the secondary windings into high-voltage power that can jump the gap between the electrodes of the spark plug; this is called inductance.
