Good afternoon, im not sure that a generic scanner will be able to perform this. Here is the actual procedure when replacing the trans.......

 

TRANSMISSION CONTROL MODULE INITIALIZATION



NOTE: Refer to the following table when the Transmission Control Module (TCM) and/or transaxle has been replaced to determine if the TCM memory must be erased.

RELEARN, AFTER REPLACING A TRANSAXLE

1.Turn ignition key to RUN.
2.Clear learning memory using the scan tool.
3.Turn the ignition key to OFF/LOCKED for 2 seconds.
4.Turn the ignition key to RUN Clear DTCs.
5.Turn the ignition key to OFF/LOCKED for 2 seconds.
6.Turn ignition key to RUN.
7.After at least 7 seconds, read DTCs.

 

 

You most likely have the same info. Resetting the learned memory is not the same thing as clearing the codes. You may need the factory scanner to perform this unfortunately. It also helps if you were able to give the actual code number.

THE CODE # XXXXX XXXXX P167A
Expert:  vipertech763 replied 8 years ago.

There is a related technical service bulletin for this code. It stated to flash (reprogram) both the pcm and tcm with the latest software updates. The bulletin # XXXXX XXXXX

 

The test for the code also states to perform the relearn. After just having replaced the trans, I would perform the relearn with the correct scanner and not worry about the service bulletin at this time.

 

P167A-CALIBRATION MISMATCH

 

Theory of Operation

During the initial ignition on, the Transmission Control Module (TCM) receives the calibrated data from the EEPROM assembly inside the transmission and stores this information in the EEPROM of the TCM. At every ignition on, the TCM compares the stored data in the EEPROM to the transmitted data from the EEPROM in the transmission. If the calibration data does not match the DTC will set and the MIL will illuminate after one failure.

  1. When Monitored:

    One time at initial ignition on with a system voltage between 9.0 and 16.0 volts.

  2. Set Condition:

    If the TCM stored calibration does not match the EEPROM assembly in the transmission. This DTC requires only one problem identification to set the MIL.


Possible Causes

TRANSMISSION CONTROL MODULE RELEARN PROCEDURE NOT PERFORMED


PERFORM TCM RELEARN PROCEDURE





Repair

  1. This is an informational DTC indicating that the TCM, CV Transmission, or the CV Transmission internal controller (valve body) was replaced without being calibrated. With the scan tool perform a Re-initialize CVT procedure.
