P1589

K41B CVT: CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM: P1589: Acceleration Sensor Learning Value
P1589 - Acceleration Sensor Learning Value

DESCRIPTION

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.





INSPECTION PROCEDURE

NOTICE:
Perform the universal trip to clear permanent DTCs Reading and Clearing Diagnostic Trouble Codes.

PROCEDURE

1. PERFORM INITIALIZATION (DECELERATION SENSOR 0 POINT CALIBRATION)

(a) Perform the deceleration sensor 0 point calibration Programming and Relearning.

Result





B -- CHECK YAW RATE AND ACCELERATION SENSOR
A -- Continue to next step.

2. PERFORM CVT OIL PRESSURE CALIBRATION

(a) Perform the CVT oil pressure calibration Programming and Relearning.

NEXT -- END

3. CHECK YAW RATE AND ACCELERATION SENSOR

(a) Check the yaw rate and acceleration sensor for any inclination, bracket deformation or installation clearance.

OK:

The yaw rate and acceleration sensor is installed correctly.

NG -- SECURELY INSTALL YAW RATE AND ACCELERATION SENSOR
OK -- Continue to next step.

4. READ VALUE USING TECHSTREAM (G SENSOR) P1585

B -- REPLACE YAW RATE AND ACCELERATION SENSOR
A -- Continue to next step.

5. REPLACE ECM P0705

NEXT -- Continue to next step.

6. PERFORM INITIALIZATION P0705

NEXT -- END

7. REPLACE YAW RATE AND ACCELERATION SENSOR P1585

NEXT -- Continue to next step.

8. PERFORM INITIALIZATION P0705

NEXT -- END
