DTC P1701 TRANSMISSION CONTROL MODULE (POWER SUPPLY)PFP:31036
DescriptionACS007C0
When the power supply to the TCM is cut “OFF”, for example because the battery is removed, and the self-
diagnostics memory function stops, malfunction is detected.
On Board Diagnosis LogicACS007C1

This is not an OBD-II self-diagnostic item.

Diagnostic trouble code “TCM-POWER SUPPLY” with CONSULT-II is detected when TCM does not
receive the voltage signal from the battery power supply.

This is not a malfunction message. (Whenever shutting “OFF” a power supply to the TCM, this message
appears on the screen.)
Possible CauseACS007C2
Harness or connectors
(Battery or ignition switch and TCM circuit is open or shorted.)
DTC Confirmation ProcedureACS007C3
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch “OFF”
and wait at least 10 seconds before performing the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch “ON”. (Do not start engine.)
2. Select “DATA MONITOR” mode for “A/T” with CONSULT-II.
3. Wait for at least 2 consecutive seconds.
4. If DTC is detected, go to AT- 1 3 1 , "
