INTRODUCTION: REPAIR INSTRUCTION: INITIALIZATION (Continued)
23. OBTAIN ZERO POINT OF YAW RATE AND ACCELERATION SENSOR (When not Using Techstream) (Vehicle Stability Control System)
NOTICE:
* While obtaining the zero points, 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 in the straight-ahead position.
(3) Check that the shift lever is in the P position.
(4) Turn the ignition switch on (IG).
(5) The warning light and indicator light come on for 3 seconds to indicate that the initial check is completed.
(6) Using SST, connect and disconnect terminals TS and CG of the DLC3 4 times or more within 8 seconds.
SST : 09843-18040
(7) Check that the slip indicator light comes on.
NOTICE:
If the ignition switch is turned on (IG) for more than 15 seconds with the shift lever in the P position after the zero points of the yaw rate and acceleration sensor have 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 the zero point calibration of the yaw rate and acceleration sensor.
(1) Turn the ignition switch off.
(2) Check that the steering wheel is in the straight-ahead position.
(3) Check that the shift lever is in the P position.
NOTICE:
DTCs 36 (zero point calibration of yaw rate sensor undone) and 39 (zero point calibration of acceleration sensor undone) will be recorded if the shift lever is not in the P position.
(4) Using SST, connect terminals TS and CG of the DLC3.
SST : 09843-18040
(5) Turn the ignition switch on (IG).
(6) After Test Mode has been entered, keep the vehicle stationary on a level surface for 2 seconds or more.
(7) Check that the slip indicator light comes on for several seconds and then blinks in Test Mode.
HINT
* The TRAC OFF indicator light remains on during Test Mode because TRAC is prohibited.
* If the slip 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.
(8) Turn the ignition switch off and disconnect SST from the DLC3.
24. ZERO POINT CALIBRATION (Occupant Classification System)
