How does the TPMS work on a Hyundai?
Hi‐line systems show the driver individual tire positions and air pressures of all tires. Lo‐line systems do not show individual tire positions and only alter that one of the 4 tires is under inflated. Some models switched systems mid‐year, so be aware of the type of TPMS you are servicing.
When does the TPMS warning light come on?
When low tire pressure or rapid deflation is detected, the low-pressure warning light on the instrument cluster will be illuminated. If the system detects a module, receiver or sensor fault, the TPMS warning indicator on the instrument cluster will be illuminated. The early system had the warning lamps directly wired to the instrument clusters.
When does tire pressure sensor shut off TPMS?
Corrected tire inflation pressure will cause the TPMS indicator to shut off once the tire pressure sensor reports to the TPMS receiver, approximately 20 minutes after the vehicle stops moving, or after 20 minutes of continuous driving.
How does the tire pressure monitor work on a Hyundai?
Starting with the LF tire, use the scan tool to scan each sensor in the following order: LF, RF, RR, LR (and full size spare if equipped). Turn ignition to the ON position with the engine OFF (not the ACC position). Connect the scan tool to the OBDII port and upload the sensor IDs.

What to do if your TPMS light comes back on?
If you take your vehicle to your dealership or a dealer-recommended repair shop, they will likely be able to fix it in minutes with a scan tool. Sometimes, if the TPMS light comes back on, it may indicate a larger problem. Any of the following may be true: One of the tires may have a slow leak.

When does the low tire pressure light turn off?
The low tire pressure light, also know as the TPMS system, on your car should turn off when you have filled your tires to the proper pressure, or “PSI.” Sometimes, it just doesn’t work though.
