Yeah, but do they continue operating the ABS and other traction control functions when they detect a low pressure condition? I've heard that the computer can disable ABS and/or traction control with a TPMS condition.Direct TPMS doesn't interface with the ABS System at all.
Indirect TPMS has no sensor in the wheel and the low pressure lamp is triggered by the different rotational speed of the low tires pressure. It will be faster than a properly inflated tire.

Direct TPMS uses a sensor mounted in the wheel to measure air pressure in each tire. When air pressure drops 25% below the manufacturer’s recommended level, the sensor transmits that information to your car’s computer system and triggers your dashboard indicator light.
Indirect TPMS works with your car’s Antilock Braking System’s (ABS) wheel speed sensors. If a tire’s pressure is low, it will roll at a different wheel speed than the other tires. This information is detected by your car’s computer system, which triggers the dashboard indicator light.
