CIRCUIT DESCRIPTION
If the ECM detects a trouble, the MIL lights up. At this time, the ECM records a DTC in the memory.

PRECAUTION
NOTICE:
Perform the RESET MEMORY (AT initialization) when replacing the automatic transmission assy, en-
gine assy or ECM (See page DI±543).
HINT:
RESET MEMORY cannot be completed by only disconnecting the battery terminal.
NOTICE:
When disconnecting the battery terminal, initialize the following system after the terminal is recon-
nected.

FREEZE FRAME DATA
Freeze frame data records the engine conditions (fuel system,
calculated load, engine coolant temperature, fuel trim, engine
speed, vehicle speed, etc.) when a malfunction is detected.
When troubleshooting, freeze frame data can help determine
if the vehicle was running or stopped, if the engine was warmed
up or not, if the air/fuel ratio was Lean or Rich, and other data
from the time the malfunction occurred.
The hand±held tester records freeze frame data in five different
instances: 1) 3 times before the DTC is set, 2) once when the
DTC is set, and 3) once after the DTC is set. These data can be
used to simulate the vehicle's condition around the time when
the malfunction occurred. The data may help find the cause of
the malfunction, or judge if the DTC is being caused by a tempo-
rary malfunction or not.
DLC3 (Data Link Connector 3)
The vehicle's ECM uses the ISO 15765±4 for communication
protocol. The terminal arrangement of the DLC3 complies with
SAE J1962 and matches the ISO 15765±4 format.
HINT:
Connect the cable of the hand±held tester to the DLC3, turn the
ignition switch ON and attempt to use the hand±held tester. If
the screen displays UNABLE TO CONNECT TO VEHICLE, a
problem exists in the vehicle side or the tester side.
If the communication is normal when the tool is connected to
another vehicle, inspect the DLC3 on the original vehicle.
If the communication is still impossible when the tool is con-
nected to another vehicle, the problem is probably in the tool it-
self. Consult the Service Department listed in the tool's instruc-
tion manual.

CHECK BATTERY VOLTAGE
Battery voltage: 11 to 14 V
If voltage is below 11 V, replace the battery before proceeding.
CHECK MIL
(a) Check that the MIL illuminates when turning the ignition
switch ON.
If the MIL does not illuminate, there is a problem in the MIL cir-
cuit (refer to MIL CIRCUIT on page DI±512)
(b) When the engine is started, the MIL should turn off.
ALL READINESS
For this vehicle, using the hand±held tester allows readiness
codes corresponding to all DTCs to be read. When diagnosis
(normal or malfunctioning) has been complete, readiness
codes are set. Enter the following menus: ENHANCED OBD II
/ MONITOR STATUS on the hand±held tester.

CHECK MODE PROCEDURE
DESCRIPTION
Check mode has a higher sensitivity to malfunctions and can
detect malfunctions that normal mode cannot detect. Check
mode can also detect all the malfunctions that normal mode can
detect. In check mode, DTCs are detected with 1±trip detection
logic.
CHECK MODE PROCEDURE
(a) Make sure that the items below are true:
(1) Battery positive voltage 11 V or more
(2) Throttle valve fully closed
(3) Transmission in the P or N position
(4) A/C switched OFF
(b) Turn the ignition switch OFF.
(c) Connect the hand±held tester together with the Controller
Area Network Vehicle Interface Module (CAN VIM) to the
DLC3.
(d) Turn the ignition switch ON.
(e) Enter the following menus: DIAGNOSIS / ENHANCED
OBD II / CHECK MODE.
(f) Change the ECM to check mode. Make sure the MIL
flashes as shown in the illustration.
NOTICE:
All DTCs and freeze frame data recorded will be erased if:
1) the hand±held tester is used to change the ECM from
normal mode to check mode or vice±versa; or 2) during
check mode, the ignition switch is turned from ON to ACC
or LOCK.
Before check mode, make notes of the DTCs and freeze
frame data.
(g) Start the engine. The MIL should turn off after the engine
starts.
(h) Perform ºMONITOR DRIVE PATTERNº for the ECT test
(See page DI±551).
(Or, simulate the conditions of the malfunction described
by the customer).
(i) After simulating the malfunction conditions, use the
hand±held tester diagnosis selector to check the DTC
and freeze frame data.

CIRCUIT INSPECTION
DTC P0705 Transmission Range Sensor Circuit Mal-
function (PRNDL Input)
CIRCUIT DESCRIPTION
The park/neutral position switch detects the shift lever position and sends signals to the ECM.
DTC No.DTC Detection ConditionTrouble Area
P0705
(2±trip detection logic)

All switches are OFF simultaneously for NSW, R, N, D, 3 and
2 positions.

2 or more switches are ON simultaneously for NSW, R, D, 3
and 2 positions.

Open or short in park/neutral position switch circuit

Park/neutral position switch

ECM
MONITOR DESCRIPTION
These DTCs indicate a problem with the park/neutral position switch and the wire harness in the park/neutral
position switch circuit.
The park/neutral position switch detects the shift lever position and sends a signal to the ECM.
For security, the park/neutral position switch detects the shift lever position so that engine can be started
only when the shift lever is in the P or N position.
The park/neutral position switch sends a signal to the ECM according to the shift position (NSW, R, D, 3 or
2).
The ECM determines that there is a problem with the switch or related parts if it receives more than 1 position
signal simultaneously. The ECM will turn on the MIL and store the DTC.
