P1701 TRANSMISSION CONTROL MODULE (POWER SUPPLY)
Description
INFOID:0000000003806449
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, a malfunction is detected.
NOTE:
Since “P1701 TCM-POWER SUPPLY” will be indicated when replacing TCM, perform diagnosis after
erasing “SELF-DIAG RESULTS”.

DTC CONFIRMATION PROCEDURE
NOTE:
If “DTC CONFIRMATION PROCEDURE” has been previously conducted, always turn ignition switch
OFF. Then wait at least 10 seconds before conducting the next test.
Perform the following procedure to confirm the malfunction is eliminated after the repair.
1.
CHECK DTC DETECTION
With CONSULT-III
1.
Turn ignition switch ON.
2.
Wait for at least 2 consecutive seconds.
3.
Select “Self Diagnostic Results” mode for “TRANSMISSION”.
Is “P1701 TCM-POWER SUPPLY” detected?
YES
>> Go to
NO
>> Check intermittent incident. Refer to
GI-35, "Intermittent Incident"
.
Diagnosis Procedure
INFOID:0000000003806451
1.
CHECK TCM POWER SOURCE
1.
Turn ignition switch OFF.
2.
Disconnect TCM connector.
3.
Check voltage between TCM vehicle side harness connector terminals.

Possible cause
P1701
TCM-POWER SUPPLY
• When the power supply to the
TCM is cut off, for example
because the battery is re-
moved, and the self-diagno-
sis memory function stops.
• This is not a malfunction
message (Whenever shutting
off a power supply to the
TCM, this message appears
on the screen).
• Harness or connectors
(Battery or ignition switch and
TCM circuit is open or short-
ed.)
