DTC P0560 (FLASHING CODE 25) System Voltage Error
RTW37ALF000701
Circuit Description
The Transmission Control Module (TCM) monitors the
system voltage on the ignition feed terminal to the
TCM. A system voltage DTC will set whenever the
voltage is below or above a calibrated value.
Condition for setting the DTC
When the TCM detects following conditions.
Ignition voltage is less than 9V or more than 18V.
Engine speed is more than 600 rpm.
Action Taken When The DTC Sets
DTC stored.
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.

TRANSMISSION CONTROL SYSTEM (AW30–40LE) (V6 3.5L) 7A2-37
DTC P0602 (FLASHING CODE 63) Transmission Control Module (TCM)
Programming Error
Circuit Description
The Service Programming System (SPS) updates the
flash calibration files that are stored in a Transmission
Control Module (TCM). The calibration file
custom-tailors a module to a certain vehicle. The
calibration file contains data for things such as spark
curves and fuel control. When troubleshooting a
driveability problem, diagnosis may call fo
r
reprogramming the controller with newer calibration
information to correct a customer concern and Vehicle
Identification Number (VIN).
Condition for setting the DTC
When the TCM is not written VIN No.
Action Taken When The DTC Sets
DTC stored.
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
DTC P0602 is indicated when the TCM does not written
VIN No. A security lock is performed by SPS. And not
replace the TCM when DTC P0602 can repair by SPS.

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.

No 3rd start mode.
No slope control.
The TCM judges always D range position of range
sensor at "Condition 1".
The TCM judges the position of range sensor with
following priority at "Condition 2".
There is a priority in order of D, 3, 2, L, R, N, and P.
