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 

TM-249, "Diagnosis Procedure"

.

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.

DTC

(CONSULT-III screen term)

Malfunction is detected when...

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.)
