Nissan Versa (N17): Additional service when replacing transaxle assembly

Nissan Versa 2nd generation (N17) Service Manual / Transmission & driveline / Transaxle & transmission (TM) / Additional service when replacing transaxle assembly

Description

Perform the following work after the transaxle assembly is replaced.

ERASING AND LOADING OF THE CALIBRATION DATA

  • The TCM acquires calibration data (individual characteristic value) of each solenoid that is stored in the ROM assembly (in the control valve). This enables the TCM to perform accurate control. For this reason, after the transaxle assembly is replaced, it is necessary to erase the calibration data that is stored in the TCM and load new calibration data.

    ERASING THE LEARNED VALUE DATA

  • TCM learns indicated pressure for appropriate control of the transaxle assembly and records the learned values. For this reason, the leaned values stored in TCM must be erased after replacing a transaxle assembly.

Work Procedure

1.INITIALIZE TCM

With CONSULT

  1. Set parking brake.
  2. Turn ignition switch ON.
  3. Select "Work Support" in "TRANSMISSION".
  4. Select "ERASE MEMORY DATA".
  5. While maintaining the conditions below, touch "Start".
  • Vehicle stop status
  • With engine stopped
  • Selector lever: "R" position
  • Accelerator pedal: Depressed

NOTE: Select "Start" and complete within approximately 20 seconds.

Is "COMPLETED" displayed?

NO >> Turn ignition switch OFF and wait for a minimum of 20 seconds then perform the work again.

2.CHECK AFTER TCM IS INITIALIZED

With CONSULT

  1. Turn ignition switch OFF with the selector lever in "R" position and wait for 20 seconds or more.
  2. Turn ignition switch ON with the selector lever in "R" position.

CAUTION: Never start the engine.

  1. Select "CALIB DATA" in "TRANSMISSION".
  2. Check that indicated value of "CALIB DATA" is equal to the value shown in the following table. 

Is the indicated value of "CALIB DATA" equal to the value shown in the table?

YES >> GO TO 3.

NO >> GO TO 1.

3.CHECK LOADING OF CALIBRATION DATA

  1. Shift the selector lever to the "P" position.
  2. Check that "P" is displayed on shift position indicator on combination meter.

NOTE: Displayed approximately 5 seconds after the selector lever is moved to the "P" position.

Does shift position indicator display "P"?

YES >> WORK END

NO >> GO TO 4.

4.DETECT MALFUNCTION ITEMS

Check the following items:

  • Harness between the TCM and the ROM assembly inside the transaxle assembly is open or shorted.
  • Disconnected, loose, bent, collapsed, or otherwise abnormal connector housing terminals

Is the inspection result normal?

YES >> GO TO 1.

NO >> Repair or replace the malfunctioning parts.
