TPM

[tyrone]

Had to change out a battery that bit the dust and when I did that, all the tpms went to zero. Normal stuff. Now I have one tpm that remains at zero. There is correct pressure air in that tire so, the question is now what? Anyone have the same issue before ? Thanks.

Have you driven the car since the battery changeout? I takes some time for them to reset. When the vehicle is stationary for more than 20 minutes, the sensors go into power down mode. In this mode the sensors transmit tire pressure data once every 60 minutes. This minimizes sensor battery consumption. These batteries are not servicable and require sensor replacement. Vehicle speed at 20MPH or more 'turns ON' the sensors and they begin to transmit unique ID codes and RF frequency signals. The RCDLR receives and translates the data into tire location and tire pressure.

If they are not 'resetting' and transmitting data, you may have a bad sensor or may need to be re-learned. You may also receive a 'SERVICE TIRE MONITOR' on the DIC if the RCDLR detects a malfunction of the system.

After I drive the car for a few miles the LF and RR show a value. After more time driving , the RF has a value. The LR still shows 0. No problem before the battery change out. Its gotta be something stupid. Maybe the relearn process needs to happen. Thanks.
