Upon finishing the data transfer, Tech-2 will
display "Reprogramming Successful". Push the
"Exit" button to bring program to completion.

9.
Following "Procedure 2: Demand of Data", try ove
r
again "Information Obtaining" and check to
confirm if the data has been correctly re-loaded.

16 – Terminal Data Link Connector (DLC)
OBD standardizes Data Link Connector (DLC)
configurations. The DLC, formerly referred to as the
ALDL, will be a 16 –terminal connector found on the
lower right side of the driver's side instrument panel. All
manufacturers must conform to this 16 –terminal
standard.

DTC P0705 (FLASHING CODE 17) Transmission Range Sensor Circuit
Malfunction


RTW37ALF000501

Circuit Description
The neutral start switch gives the signals related to the
selector lever position (PRND32L) to the Transmission
Control Module (TCM). The neutral start switch turns on
when the select lever is shifted to the P, R, N, D, 3, 2 o
r
L range. The neutral start switch, which is connected to
the starter switch circuit, is available only when the
select lever is in the P or N range (Engine run).
The neutral start switch is connected to the
transmission manual shaft and installed in the
transmission case.

Condition for setting the DTC

The TCM detects following "Condition 1" for 30 sec
continuously.
 The TCM detects following "Condition 2" for 10 sec
continuously.
Condition 1("Open"):
When the TCM detects no signal of range senso
r
more than 2.0 sec at following conditions.

C.

No detect DTC P0712, 0713.
 No detect DTC P0560.
Conditions For Clearing The DTC

The DTC can be cleared from the TCM history by
using a scan tool.
 The DTC will be cleared from history when the
vehicle has achieved 40 warm-up cycles without a
failure reported.

After more than 1 second has elapsed after the
ignition key has been turned “ON", short between
No.11 and No.4 (ground) of DLC (Data Link
Connector). Then, after 1 second, but within 6
seconds, discontinue shorting.
Diagnostic Aids

Inspect the wiring for poor electrical connection at
the TCM. Look for possible bent, backed out,
deformed or damaged terminals. Check for weak
terminal tension as well. Also check for a chafed wire
that could short to bare metal or other wiring. Inspect
for a broken wire inside the insulation.

When diagnosing for a possible intermittent short o
r
open condition, move the wiring harness while
observing test equipment for a change.

Inspect the wiring for EMI (Erectro-Magnetic
Interference). Check that all wires are properly
routed away from coil, and generator. Also check fo
r
improperly installed electrical options. When this test
is performed, turn “OFF" on electronic autoparts
switches to improperly for a noise preventing.
