P1701 TCM

Description

INFOID:0000000009719493

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” is indicated when replacing TCM, perform diagnosis after erasing “Self Diagnostic Results”.

DTC DETECTION LOGIC

DTC CONFIRMATION PROCEDURE

NOTE:
Immediately after performing any “DTC CONFIRMATION PROCEDURE”, always turn ignition switch OFF.
Then wait at least 10 seconds before performing the next test.

1.

CHECK DTC DETECTION

With CONSULT

1.

Turn ignition switch ON.

2.

Wait for at least 2 consecutive seconds.

3.

Perform “Self Diagnostic Results” in “TRANSMISSION”.

Is “P1701” detected?

YES

>> Go to 

TM-87, "Diagnosis Procedure"

.

NO

>> Check intermittent incident. Refer to 

GI-44, "Intermittent Incident"

.

Diagnosis Procedure

INFOID:0000000009719495

1.

CHECK TCM POWER SOURCE

1.

Turn ignition switch OFF.

2.

Disconnect TCM connector.

3.

Check voltage between TCM vehicle side harness connector terminals.

Is the inspection result normal?

YES

>> GO TO 6.

NO

• When the power supply to the TCM is cut 

off, for example because the battery is re-
moved, and the self-diagnosis memory 
function stops.

• This is not a malfunction message (When-

ever shutting off a power supply to the 
TCM, this message appears on the 
screen).
