DTC TROUBLESHOOTING C0077-78: LOW TIRE AIR PRESSURE
NOTE:
- Before troubleshooting, check the outside air temperature sensor. If
outside air temperature sensor is
failed, the VSA modulator-control unit may set this code.
- Make sure to avoid lopsided loading on one side (left or right) of the
vehicle and excessive loading.
- Make sure to inflate the tires to recommended pressure, not higher than
the specified pressure, when
TPMS calibration is being performed.
- Before you troubleshoot, review the general troubleshooting information.
1. Tire pressure check:
- Turn the vehicle to the OFF (LOCK) mode.
- Check all four tires for size, inflation, and wear.
Are all four tires the correct size, properly inflated, and worn evenly?
YES
The system is OK at this time. Do the TPMS calibration.
NO
Install the correct tires, a known-good set of tires, or set the tires to the
correct pressure, and do the
TPMS calibration.
DTC TROUBLESHOOTING C0078-4A: DIFFERENT DIAMETER TIRE DETECTION
NOTE:
- The DTC will be indicated when the vehicle has a different diameter
tire(s) compared to the other tires.
- Check the record of using tires and wheels of a different size from
originally supplied with the vehicle
including the use of temporary spare tire.
- Before you troubleshoot, review the general troubleshooting information.
1. Tire and wheel check:
- Turn the vehicle to the OFF (LOCK) mode.
- Check all four tires for size, inflation, and wear.
Are all four tires the correct size, properly inflated, and worn evenly?
YES
The system is OK at this time. Do the TPMS calibration.
NO
Install the correct tires, a known-good set of tires, or set the tires to the
correct pressure, and do the
TPMS calibration.

Is DTC C1030-13 indicated?
YES
The failure is duplicated. Go to step 2.
NO
Intermittent failure, the system is OK at this time. If the freeze
data/on-board snapshot of this DTC is recorded, try to reproduce the failure
under the same conditions with the Freeze data/on-board snapshot.
2. Open wire check (TPMS SW line) 1:
- Turn the vehicle to the OFF (LOCK) mode.
- Disconnect the following connector.
TPMS switch 5P connector.
- Turn the vehicle to the ON mode.
- Measure the voltage between test points 1 and 2.
Is there battery voltage?
YES
The TPMS SW wire is not open. Go to step 3.
NO
Go to step 4.
3. Open wire check (GND line):
Measure the voltage between test points 1 and 2.
Is there battery voltage?
YES
The GND wire is OK. Check the TPMS switch.
NO
Repair an open in the wire between the TPMS switch and body ground (G501).
4. Open wire check (TPMS SW line) 2:
- Turn the vehicle to the OFF (LOCK) mode.
- Remove the gauge control module (Do not disconnect the connector).
- Turn the vehicle to the ON mode.
- Measure the voltage between test points 1 and 2.
Is there battery voltage?
YES
Repair an open in the wire between the TPMS switch and the gauge control
