P1701 TCM

Description

INFOID:0000000012200973

When the power supply to the TCM is cut OFF, for example because the battery is removed, and the self-diag-

nosis memory function stops, malfunction is detected.

CAUTION:

Immediately after TCM is replaced or after control valve or transaxle assembly is replaced (after TCM

initialization is complete), self-diagnosis result of “P1701” may be displayed. In this case, erase self-

diagnosis result using CONSULT. After erasing self-diagnosis result, perform DTC P1701 reproduction

procedure and check that malfunction is not detected.
