DTC P1701 Transmission Control Module (Power Supply): Description

WARNING: This page is about a different car, the 2007 Nissan Sentra. However, it is still accessible from the selected car via links, so may be relevant.

When the power supply to the TCM is cut OFF, for example because the battery is removed, and the self-diagnosis memory function stops, malfunction is detected.

NOTE: Since "P1701 TCM-POWER SUPPLY" will be indicated when replacing TCM, perform diagnosis after erasing "SELF-DIAG RESULTS"
