INTRODUCTION: REPAIR INSTRUCTION: INITIALIZATION - (Continued)
12. REGISTER TRANSMITTER ID (Using Techstream) (Tire Pressure Warning System)
(a) Set all tire pressures to the specified value(s) Service Precautions.
(b) Turn the ignition switch off.
(c) Connect the Techstream to the DLC3.
(d) Turn the ignition switch to ON.
(e) Turn the Techstream on.
(f) Enter the following menus: Chassis / Tire Pressure Monitor / Utility / ID Registration.
(g) Follow the ID Registration steps displayed the Techstream screen.
(h) Confirmation of transmitter ID registration.
(1) Enter the following menus: Chassis / Tire Pressure Monitor / Data List.
(2) Read the "ID Tire Inflation Pressure" values.
(3) Confirm that the tire pressure data of all tires are displayed on the Techstream.
NOTICE:
* It takes about 2 or 3 minutes to display the updated tire pressure data. If the values are not displayed after a few minutes, perform troubleshooting according to the inspection procedure for DTCs C2121/21 to C2124/24 C2121.
* If the IDs have not been registered, DTC C2171/71 is set in the tire pressure warning ECU after 3 minutes or more.
* If normal pressure values are displayed, the IDs have been registered correctly.
* If the tire pressure values are not displayed after a few minutes, the IDs may be incorrect or the system may have a malfunction.
* After all IDs are registered, DTC C2126/26 (Transmitter ID not Received) is set in the tire pressure warning ECU and the tire pressure warning light blinks for 1 minute and then comes on. When the tire pressure warning ECU successfully receives signals from all the transmitters whose IDs are stored in the ECU, DTC C2126/26 is cleared and the tire pressure warning light goes off.
13. INITIALIZATION PROCEDURE (Tire Pressure Warning System)
(a) Adjust all tire pressures to the standard tire inflation pressure, as indicated on the tire and loading information label on the vehicle.
(b) Turn the ignition switch to ON.
(c) Push and hold the tire pressure warning reset switch for 3 seconds or more so that the tire pressure warning light blinks 3 times.
(d) Turn the ignition switch off.
(e) Connect the Techstream to the DLC3.
(f) Turn the ignition switch to ON.
(g) Turn the Techstream on.
(h) Enter the following menus: Chassis / Tire Pressure Monitor / Data List.
(i) Check that initialization has been completed.
(j) Confirm that tire pressure data of all wheels are displayed on the Techstream.
NOTICE:
* Initialization normally completes within 2 or 3 minutes.
* If initialization did not complete successfully, DTC C2177/77 will be set after a vehicle speed 8 km/h (5 mph) or more continues for 20 minutes or more.
* Initialization can be terminated by connecting terminals TC and CG of the DLC3.
HINT
* The initialization is completed when the "ID Tire Inflation Pressure" display shows the correct pressures.
* *: It may take about 2 or 3 minutes until the values are displayed. If the values are not displayed after a few minutes, perform troubleshooting according to the inspection procedure for DTCs C2121/21 to C2124/24 C2121.
14. OBTAIN ZERO POINT OF YAW RATE AND ACCELERATION SENSOR (When Using the Techstream) (Vehicle Stability Control System)
NOTICE:
* While obtaining the zero point, keep the vehicle stationary and do not vibrate, tilt, move, or shake it. (Do not start the engine.)
* Be sure to perform this procedure on a level surface (with an inclination of less than 1 degree).
(a) Clear the zero point calibration data.
(1) Turn the ignition switch off.
(2) Check that the steering wheel is centered.
(3) Check that the shift lever is in P (for automatic transaxle) or the parking brake is applied (for manual transaxle).
(4) Connect the Techstream to the DLC3.
(5) Turn the ignition switch to ON.
(6) Turn the Techstream on.
(7) Select the skid control ECU to clear the zero point calibration data using the Techstream. Enter the following menus: Chassis / ABS/VSC/TRAC / Utility / Reset Memory.

NOTICE:
If the ignition switch is turned to ON for more than 15 seconds with the shift lever in P (for automatic transaxle) or the parking brake applied (for manual transaxle) after zero point of the yaw rate and acceleration sensor has been cleared, only the zero point of the yaw rate sensor will be stored. If the vehicle is driven under these conditions, the skid control ECU will store the zero point calibration for the acceleration sensor as not being completed. The skid control ECU will then also indicate this as a malfunction of the VSC system using the indicator lights.
(b) Perform zero point calibration of the yaw rate and acceleration sensor.
(1) Turn the ignition switch off.
(2) Check that the steering wheel is centered.
(3) Check that the shift lever is in P (for automatic transaxle) or the parking brake is applied (for manual transaxle).
NOTICE:
DTCs C1210/36 and C1336/39 will be recorded if the shift lever is not in P (for automatic transaxle) or the parking brake is not applied (for manual transaxle) C1210.
(4) Connect the Techstream to the DLC3.
(5) Turn the ignition switch to ON.
(6) Turn the Techstream on.

(9) Check that the VSC OFF indicator light comes on for several seconds and then blinks in Test Mode.
HINT
* The slip indicator light remains on during Test Mode because traction control operation is prohibited (The slip indicator light goes off when the VSC OFF switch is on).
* If the VSC OFF indicator light does not blink, perform zero point calibration again.
* Zero point calibration is performed only once after the system enters Test Mode.
* Calibration cannot be performed again until the stored data is cleared.
(10) Turn the ignition switch off and disconnect the Techstream.
15. OBTAIN ZERO POINT OF YAW RATE AND ACCELERATION SENSOR (When not Using the Techstream) (Vehicle Stability Control System)

NOTICE:
If the ignition switch is turned to ON for more than 15 seconds with the shift lever in P (for automatic transaxle) or the parking brake applied (for manual transaxle) after zero point of the yaw rate and acceleration sensor has been cleared, only the zero point of the yaw rate sensor will be stored. If the vehicle is driven under these conditions, the skid control ECU will store the zero point calibration for the acceleration sensor as not being completed. The skid control ECU will then also indicate this as a malfunction of the VSC system using the indicator lights.
(b) Perform zero point calibration of the yaw rate and acceleration sensor.
(1) Turn the ignition switch off.
(2) Check that the steering wheel is centered.
(3) Check that the shift lever is in P (for automatic transaxle) or the parking brake is applied (for manual transaxle).
NOTICE:
DTCs C1210/36 and C1336/39 will be recorded if the shift lever is not in P (for automatic transaxle) or the parking brake is not applied (for manual transaxle) C1210.
(4) Using SST, connect terminals TS and CG of the DLC3.
SST : 09843-18040
(5) Turn the ignition switch to ON.
(6) Keep the vehicle stationary on a level surface for 2 seconds or more.
