system monitors faults within the system. When any
fault has been set, the TPM system will display TIRE
SENSOR BAD/MISSING. Be sure to inspect your tires for
proper inflation pressure. After you determine that your
tires are properly inflated, see your authorized dealer for
service to diagnose the problem with the TPM system.5. With the 5 Tire TPM System, if a road tire is replaced
by the spare, the TPM system will automatically detect
that the tires have been switched (after the ignition has
been cycled) and display SPARE SWAP DETECTED
along with a chime. This could take up to 10 minutes
with vehicle speed above 25 mph (40 km/h).
6. With the 4 Tire TPM System, if a road tire is replaced
by the spare, the TPM system will display TIRE SENSOR
BAD/MISSING. This is due to the spare tire not being
equipped with a tire pressure sensor. Once the road tire is
repaired and/or installed back on the vehicle with the
proper tire pressure the message will be removed. This
could take up to 10 minutes with vehicle speed above 25
mph (40 km/h).
