Toyota Corolla Cross: Tire Position Not Identified
DESCRIPTION
The tire pressure warning ECU and receiver identifies the tire position for each tire pressure warning valve and transmitter according to the wheel speed signals from the skid control ECU (brake actuator assembly) and acceleration rate signal from each acceleration sensor built into each tire pressure warning valve and transmitter.
CAUTION / NOTICE / HINT
NOTICE:
- When replacing the tire pressure warning ECU and receiver, first use the GTS to record all of the current IDs and registered tires with transmitters of the tire pressure warning valve and transmitter registered to the tire pressure warning ECU and receiver.
- It is necessary to perform initialization after registration of the transmitter
IDs into the tire pressure warning ECU and receiver if one of the valve and
transmitters has been replaced.

(c) Rapidly reduce the tire pressure for each wheel at least 40 kPa (0.4 kgf/cm2, 5.8 psi) within 30 seconds.
NOTICE:
- It may take a few minutes until the values are displayed.
- When an "ID Tire Inflation Pressure" value has not changed, reset the tire pressure to the appropriate specified value and rotate the tire 90 to 270 degrees. Then rapidly release the tire pressure and recheck the value.
(d) Read the "ID Tire Inflation Pressure" value and identify the tire with reduced pressure, and record the corresponding tire pressure warning valve and transmitter (ID1 to ID4).
(e) Repeat for each tire.
(f) Set the tire pressure to the specified value.

2. |
PERFORM INITIALIZATION |
(a) Leave the vehicle with the ignition switch turned off for 15 minutes or more.
HINT:
After the vehicle has been stopped for 15 minutes or more, the tire pressure warning valve and transmitter will transmit radio wave signals more frequently for the first several minutes of driving (4 times more frequent than usual).
(b) Perform initialization to clear the existing tire position information.

3. |
IDENTIFY TIRE POSITION DURING DRIVING |
(a) Drive the vehicle at 40 km/h (25 mph) or more for 10 to 30 minutes in 1 trip.
HINT:
Do not drive the vehicle in reverse gear while performing Tire Position Identification. If the vehicle is driven in reverse gear while performing Tire Position Identification, identification information will be discarded and Tire Position Identification may take longer than usual.
(b) Without turning off the ignition switch, check the tire position for each transmitter.
