zero point calibration

Zero Point Calibration Using Jumper wire
The following manual procedure may be used in the cases where a Diagnostic Tester is
not available.
CAUTION:
While performing the Zero Point Calibration, do NOT tilt, move, or shake the vehicle.
The vehicle must remain in a stationary condition throughout the entire process.
Be sure to perform the procedure on a level surface with an inclination of less than 1%.
1. If the vehicle is equipped with A/T, ensure that the shift lever is in the P range and
the parking brake is applied. If the vehicle is equipped with a M/T, ensure that the
parking brake is applied.
2. Turn the ignition switch ON.
3. Using the SST, repeat a cycle of short and open between terminals Ts and CG of
DLC3 4 times or more within 8 seconds (refer to the specific vehicle EWD for TS and
CG pin location in the DLC3).
4. Verify that the VSC indicator light is lit indicating the recorded zero point is erased.
5. Turn the ignition switch OFF.
6. Be sure the terminals Ts and CG of DLC3 are disconnected.
7. Turn the ignition switch ON.
8. Check that the VSC warning light goes off about 15 seconds after the ignition switch
is turned ON.
9. After ensuring that the VSC warning light remains OFF for 2 seconds, turn the ignition
switch OFF.
10. Connect terminals Ts and CG of DLC3 using the SST.
11. Turn the ignition switch ON.
12. After turning the ignition switch ON, check that the VSC warning light is lit for about
4 seconds and then starts quick blinking at 0.13 second intervals.
13. After ensuring the blinking of the VSC warning light for 2 seconds, turn the ignition
switch OFF.
14. Remove the SST from terminals Ts and CG of DLC3.
15. Drive the vehicle for at least 5 minutes to confirm Zero Point Calibration is complete.
IF FAILED REPLACE THE BRAKE ACTUATOR - SKID CONTROL ECU. P1589 is an error in regards to the CVT. P1589: Acceleration Sensor Learning Value
The ECM stores DTC P1589 if the ECM or other components are replaced that require the yaw rate and acceleration sensor to be calibrated
(deceleration sensor 0 point calibration) and calibration is terminated or the vehicle is driven before calibration is complete.
