1. TPMS Overview
1. Tire Pressure Monitoring System (TPMS) OverviewThe TPMS system is designed to monitor tire pressure and alert the driver when a tire is significantly underinflated. Hyundai vehicles feature 2 types of systems termed "High-Line" and "Low-Line". High-Line systems are able to display a low pressure condition for each tire position, while Low-Line systems do not indicate which tire is underinflated.
Hyundai uses three suppliers for the TPMS systems across the vehicle line-up, TRW, Lear, and Siemens. Each of these systems operate in a very similar manner, but have some minor variations in operation as described in this TSB.
TPMS SYSTEM TYPE
TPMS Warning Lights
NOTE:
LM Tucson, YF Sonata, and 2010 CM Santa Fe do not have the "TPMS" malfunction warning light. Instead, the low tire pressure warning light will blink for approximately 60 seconds then remain on when there is a system malfunction.
NOTE:
It takes approximately 25 minutes of driving at speed (above 12 mph) for the TPMS malfunction lamp to illuminate if there is a malfunction.
