P1701 TRANSMISSION CONTROL MODULE (POWER SUPPLY)

Description

INFOID:0000000003849018

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” 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-III

1.

Turn ignition switch ON.

2.

Wait for at least 2 consecutive seconds.

3.

Perform “Self-Diagnostic Results” mode for “TRANSMISSION”.

Is “P1701 TCM-POWER SUPPLY” detected?

YES

>> Go to 

TM-85, "Diagnosis Procedure"

.

NO

>> Check intermittent incident. Refer to 

GI-35, "Intermittent Incident"

.

Diagnosis Procedure

INFOID:0000000003849020

1.

CHECK TCM POWER SOURCE

1.

Turn ignition switch OFF.

2.

Disconnect TCM connector.

3.

Check voltage between TCM vehicle side harness connector terminals.
