P1701

P1701 TCM

Description

When the power supply to the TCM is cut off, for example because the battery is removed, and the self-diagnosis memory function stops, a malfunction is detected.
Detects malfunction when power source (backup) is not supplied to TCM and learning function is stopped.

CAUTION:
"P1701" can be displayed in self diagnosis result immediately after TCM replacement and after transaxle assembly replacement (after TCM initialization operation). In this case, erase self diagnosis result using CONSULT. After erasing self diagnosis result, perform reproducing operation of "P1701"
to confirm that there is no longer malfunction.
