    • Make sure connectors that were connected to corroded areas on the junction box are cleaned even if there is no indication of corrosion.

    • Before the contact cleaner dries, use a wire brush or soft brush to clean off the corrosion.

    • On hard plastic connectors, there is no risk from damage by a wire brush.

    • Allow all components to dry for three or more hours.

Great job with this guide.

Fantastic, with good photos. My 2011 Mustang Tire Pressure Monitor system is putting up error message "Tire Pressure Sensor Fault" but the sending units in the wheels/tires are new and have been tested twice as working correctly and the TPMS system was reset, but after 30 minutes of driving the warning light flashes and the error message appears. Tire pressure is exactly what it is supposed to be. I asked the local Ford dealer what they charged to determine what is wrong with the system.......$200!.. No thanks. Then I found out the Smart Junction Box (AKA Body Control Module) is $432 from this dealer, but can be had new from other Ford dealers for as low as $290. However I strongly suspect that the only problem is a bad electrical connection, so I will follow this guide to clean the contacts and I bet that is the cure. I will post an update after I clean the contacts and verify there are no signs of overheating or failed components and if the problem is fixed.
