P1701 TCM
DescriptionINFOID:0000000005928882
When the power supply to the TCM is cut OFF, for exam ple because the battery is removed, and the self-diag-
nosis memory function stop s, malfunction is detected.
NOTE:
Since “P1701” will be indicated when replacing TCM, perform diagnosis after erasing “SELF-DIAG
RESULTS”
On Board Diagnosis LogicINFOID:0000000005928883
• This is not an OBD-II self-diagnostic item.
• Diagnostic trouble code “P1701” with CONSULT-III is detected when TCM does not receive the voltage sig- nal from the battery power supply.
• This is not a malfunction message. (Whenever shutti ng OFF a power supply to the TCM, this message
appears on the screen.)
Possible CauseINFOID:0000000005928884
Harness or connectors
(Battery or ignition switch and TCM circuit is open or shorted.)
DTC Confirmation ProcedureINFOID:0000000005928885
NOTE:
If “DTC Confirmation Procedure” has been previously conducted, always turn ignition switch OFF and
wait at least 10 seconds before conducting the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON. (Do not start engine.)
2. Select “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III.
3. Wait for at least 2 consecutive seconds.
4. If DTC is detected, go to CVT-115, "
Diagnosis Procedure" .
