9-50 Vehicle Service and Care
Your vehicle has also been
equipped with a TPMS malfunction
indicator to indicate when the
system is not operating properly.
The TPMS malfunction indicator
is combined with the low tire
pressure telltale. When the system
detects a malfunction, the telltale
will flash for approximately
one minute and then remain
continuously illuminated.
This sequence will continue upon
subsequent vehicle start-ups
as long as the malfunction exists.
When the malfunction indicator
is illuminated, the system may not
be able to detect or signal low
tire pressure as intended. TPMS
malfunctions may occur for a variety
of reasons, including the installation
of replacement or alternate tires
or wheels on the vehicle that
prevent the TPMS from functioning
properly. Always check the TPMS
malfunction telltale after replacing
one or more tires or wheels on
your vehicle to ensure that
the replacement or alternate tires
and wheels allow the TPMS to
continue to function properly.
