INTRODUCTION: REPAIR INSTRUCTION: INITIALIZATION (Continued)
17. 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 model) or the parking brake is applied (for manual transaxle model).
(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.
(8) Turn the ignition switch off.
NOTICE:
If the ignition switch is turned to ON for more than 15 seconds with the shift lever in P (for automatic transaxle model) or the parking brake applied (for manual transaxle model) 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 model) or the parking brake is applied (for manual transaxle model).
NOTICE:
DTCs C1210/36 and C1336/39 will be recorded if the shift lever is not in P (for automatic transaxle model) or the parking brake is not applied (for manual transaxle model).
(4) Connect the Techstream to the DLC3.
(5) Turn the ignition switch to ON.
(6) Turn the Techstream on.
(7) Switch the skid control ECU to Test Mode using the Techstream. Enter the following menus: Chassis / ABS/VSC/TRAC / Utility / Test Mode.
(8) After the system enters Test Mode, keep the vehicle stationary on a level surface for 2 seconds or more.
(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.
* The 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.

(4) Using SST, connect terminals TS and CG of the DLC3.
SST : 09843-18040

22. REGISTRATION OF RECOGNITION CODE (MANUAL OPERATION) (Wireless door lock control system (w/o Smart Key System))
HINT
* Register a new recognition code when replacing the door control transmitter or the door control receiver.
* Add mode is used to retain the already registered codes while registering a new recognition code. This mode is used when adding a transmitter. If the number of registered codes exceeds 6, the previously registered code will be correspondingly erased in order, starting from the code registered first.
* Rewrite mode is used to erase all the previously registered codes and register only new recognition codes. This mode is used when exchanging the transmitter or the door control receiver for new one.
* Confirmation mode is used to confirm how many recognition codes have already been registered before an additional registration of a recognition code.
* Prohibition mode is used to erase all the registered codes and cancel the wireless door lock function. Use this mode when the transmitter is lost.
* All of the steps in the following registration procedure must be performed in sequential order continuously.
(a) The following conditions should be met.
(1) No key is inserted in the ignition key cylinder.
(2) Only driver side door is opened.

Then insert the key into the ignition key cylinder and remove it.
HINT
Complete this procedure within 40 seconds.
(3) After the above operations, close and open the driver side door twice. (End in open)

HINT
* In confirmation mode, the LOCK- UNLOCK operation will occur once for each recognition code that has been registered. For example, if 2 recognition codes have been registered, the LOCK-UNLOCK operation will occur 2 times.

(c) Register new recognition codes (Add mode or Rewrite mode):
(1) Within 45 seconds after add mode or rewrite mode has been selected, press the LOCK and UNLOCK switches on the transmitter switch simultaneously for 1.0 to 1.5 seconds.
Then, press either one of the switches for more than 1.0 second (Procedure "A").
(2) Within 5 seconds after the transmitter switch has been released, the LOCK-UNLOCK operation will be automatically performed once if the registration of the recognition code of the transmitter is completed correctly.
If the LOCK-UNLOCK operation is performed twice, registration of the recognition code has failed. Perform the registration procedure from the beginning (Procedure "B").
(3) If multiple transmitters need to be registered, repeat procedures "A" and "B" within 45 seconds each.
HINT
* Up to 6 recognition codes can be registered at once.
