TROUBLE DIAGNOSIS
Description
If a malfunction occurs in electrical system, turning igni tion switch ON will illuminate OD OFF indicator lamp for
2 seconds. To detect a malfunction, entering a self-diagnosis start signal retrieves information on malfunctions
from memory and indicates malfunction by blinking OD OFF indicator lamp.
Diagnostic Procedure 1.
CHECK OD OFF INDICATOR LAMP
1. Park vehicle on flat surface.
2. Move selector lever to “P” position.
3. Turn ignition switch OFF. Wait at least 5 seconds.
4. Turn ignition switch ON. (Do not start engine.)
Does OD OFF indicator lamp come on about 2 seconds? YES >> GO TO 2.
NO >> Stop procedure. Perform AT-181, " OD OFF Indicator
Lamp Does Not Come On " before proceeding.
2.
JUDGEMENT PROCEDURE STEP 1
1. Turn ignition switch OFF.
2. Keep pressing shift lock release button.
3. Move selector lever from “P” to “D” position.
4. Turn ignition switch ON. (Do not start engine.)
5. Keep pressing overdrive control switch while OD OF F indicator lamp is lighting up for 2 seconds. (OD
OFF indicator lamp is on.)
6. Keep pressing overdrive control switch and shift select or lever to the “2” position. (OD OFF indicator lamp
is on.)
7. Stop pressing overdrive control switch. (OD OFF indicator lamp is on.)
8. Shift selector lever to the “1” position. (OD OFF indicator lamp is on.)
9. Keep pressing overdrive control switch. (OD OFF indicator lamp is off.)
10. Depress accelerator pedal fully while pressing overdrive control switch.

How to Erase Self-diagnostic Results 1. If the ignition switch stays ON after repair work, be su re to turn ignition switch OFF once. Wait for at least
5 seconds and then turn it ON again.
2. Perform "Diagnostic Procedure Without CONSULT-III" .
3. Turn ignition switch OFF. (The self-diagnostic results will be erased.) 11th judgement flicker is longer than others.
Line pressure solenoid valve circuit is short-circuited or discon-
nected.
⇒ Go to AT-134 .
12th judgement flicker is longer than others.
CAN communication line is damaged.
⇒ Go to AT-88 .
Lamp turns off.
Park/neutral position (PNP) switch, overdrive control switch,
closed throttle position signal or wide open throttle position signal
circuit is disconnected or TCM is damaged.
(Because overdrive control switch signal, closed throttle position
signal and wide open throttle position signal are input via CAN
communication line malfunction may continue after self-diagno-
sis.)
⇒ Go to AT-205, " TCM Self-Diagnosis
Does Not Activate " .

DTC P0705 PARK/NEUTRAL POSITION (PNP) SWITCH
Description INFOID:0000000004305338
• The PNP switch assembly includes a transaxle range switch.
• The transaxle range switch detects the selector lever position and sends a signal to the TCM.
CONSULT-III Reference Val ue in Data Monitor Mode INFOID:0000000004305339
On Board Diagnosis Logic INFOID:0000000004305340
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P0705 PNP SW/CIRC” with CONS ULT-III is detected when TCM does not receive
the correct voltage signal from the switch based on the gear position.
Possible Cause INFOID:0000000004305341
• Harness or connectors [The PNP switch circuit is open or shorted.]
• PNP switch
DTC Confirmation Procedure INFOID:0000000004305342
CAUTION:
• Always drive vehicle at a safe speed.
• If performing this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait at
least 10 seconds before continuing.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-III
