The TPM does not rely on the ABS. Its a true pressure system on the 300c. My understanding is there was a lawsuit between the Govt. and automakers on this point. The Govt. won, because if ALL tires were low, the ABS system wouldn't detect it. Only a true pressure system will show that condition. By the way, I ordered a 300C yesterday and I had my dealer try to find out when the system will be available. No luck. Maybe it will be on my car when it arrives.
