Re: Tire Presure Sensor Question
Hi all you TPMS fans. Haven't logged onto the Forum for a while, wondered what new wisdom might be available. And, getting close to convertible season here in Michigan!
Confirmed several times over that the only way to get a Crossfire to "relearn" new original type wheel sensors (not programmable, not cloneable, fixed sensor ID built in) is with the Chrysler dealership DRB III with the Crossfire - Sprinter Multiplexer cable with a Crossfire software card in the DRB III. Since the DRB III was superseded at Chrysler shops after 2007, more than a few dealerships have lost this gear, never had it, or won't be bothered.
(Leading to an aside: 2007 and 2008 Crossfire cars for North America may be serviceable with the later, more online dealership diagnostic equipment. Anyone confirm this? Although I believe one report somewhere here on the Forum said a 2007 owner had to track down a DRB III to get their TPMS relearn.) (And another report I saw noted that the newer equipment had to be lied to that a 2008 model year car was a 2007 before functioning.)
By now every tire shop must have one of the handheld TPMS tools which can read signals from the wheel sensors. The original factory sensors may, or may not, respond to the LF (Low Frequency) trigger signal from such a tool to report its status, including ID number. When I took my 10 year old factory sensors to get checked two of the four responded to the radio trigger, the other two waited until the TPMS magnet was put on them, then reported. But getting wheel sensor function checked by a tire shop should be quick and easy and free. Just ask them to bring their magnet with them, in case they don't get a signal with the radio trigger.
Also recognize (because a lot of tire techs will not) that a wheel sensor which sends a signal to the handheld TPMS tool 5cm away may not be reaching all the way to our Crossfire receiver up by the garage opener buttons. Some newer sensors include a battery strength report in their transmission, not the Crossfire ones.
I suspect that the supposed Siemens wheel sensors using the 315 MHz frequency might be a phantom on Crossfire. Has anyone in the USA or Canada found 315 MHz sensors in their Crossfire? I know that 315 MHz systems are generally more common than 433 MHz in North America, but wonder why such a mix would have happened for Crossfire.
And just a brief reminder that the easy way seems more and more the EZ-Sensor cloneable ID way. Other brands also available, but Schrader would be my first choice. No extra trip to a Chrysler dealership required.
