P1701 TCM

Description

INFOID:0000000009650181

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 tran-
saxle 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.
