DISCUSSION:

If the TPM system detects a low tire, it will set a low tire DTC (C0077 -Low Tire Pressure),
notify the customer by illuminating the TPM telltale, and display the low tire pressure
values in the EVIC display. Once the low road tire is replaced by the spare tire and the
vehicle is driven above 25 MPH (40 KPH) for more than 10 minutes; the TPM system will
set an additional DTC (C151C -Tire Pressure Sensor Missing), notify the customer by
displaying “CHECK TPM SYSTEM” for 3 seconds, and replaces the low tire pressure value
with dashes “--“.

If:

· The original tire with pressure sensor remains inside the vehicle or within a valid
Radio Frequency range with the WCM (TPM receiver).
And:

· The pressure changes in the low tire by more than 1 PSI or 13 hours expire from the
time the low tire event occurred.
Then:

· The dashes will be replaced by the actual low tire pressure value.
This low tire / dash “--“ cycle will repeat until the pressure is restored in the original tire.

NOTE: The spare tire is not equipped with a tire pressure monitoring (TPM) sensor.

Do not replace any TPM sensors for this condition. Correct the low tire condition first and
then verify that the C151C -Tire Pressure Sensor Missing and the C0077 -Low Tire
