DTC P1730 A/T INTERLOCKPFP:00000
DescriptionNCS00050
Fail-safe function to detect interlock conditions.
On Board Diagnosis LogicNCS00051

This is an OBD-II self-diagnostic item.

Diagnostic trouble code “P1730 A/T INTERLOCK” with CONSULT-III or 12th judgment flicker without
CONSULT-III is detected when TCM does not receive the proper voltage signal from the sensor and
switch.

TCM monitors and compares gear position and conditions of each ATF pressure switch when gear is
steady.
Possible CauseNCS00052

Harness or connectors
(Solenoid and switch circuit is open or shorted.)

Low coast brake solenoid valve

ATF pressure switch 2
DTC Confirmation ProcedureNCS00053
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON.
2. Select “MAIN SIGNALS” in “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III.
3. Touch “START”.
4. Start engine.
5. Drive vehicle and maintain the following conditions for at least 2 consecutive seconds.
SLCT LVR POSI: “D” position
6. If DTC is detected, go to AT- 1 4 2 , "
Diagnostic Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-III”.
Judgment of A/T InterlockNCS00054

When A/T Interlock is judged to be malfunctioning, the vehicle should be fixed in 2nd gear, and should be
set in a condition in which it can travel.
NOTE:
When the vehicle is driven fixed in 2nd gear, a turbine revolution sensor malfunction is displayed,
but this is not a turbine revolution sensor malfunction.

When interlock is detected at the 3rd gear or more, it is locked at the 2nd gear.
