1. CHECK BATTERY ELECTROLYTE LEVEL AND VOLT-
AGE
(a) Check the electrolyte quantity of each cell.
If under the lower level, replace the battery (or add distilled wa-
ter if possible). check the charging system.
(b) Measure the battery voltage between the negative ( −)
and positive (+) terminals of the battery.
Standard voltage: At 20° C (68°F): 12.7 − 12.9 V
HINT:
Before measuring the voltage, turn the ignition switch
OFF and turn off the electrical systems (headlight, blower
motor, rear defogger etc.).
If the vehicle has been running, wait 20 minutes or more
after the vehicle stops before measuring the battery volt-
age.
If the voltage is less than specification, charge the battery.
HINT:
Check the indicator as shown in the illustration.
2. CHECK BATTERY TERMINALS, FUSIBLE LINK AND FUSES
(a) Check that the battery terminals are not loose or cor-
roded.

1. DIAGNOSIS SYSTEM
(a) Description
When troubleshooting OBD II vehicles, the only dif-
ference from the usual troubleshooting procedure
is that you connect to the vehicle the OBD II scan
tool complying with SAE J1978 or TOYOTA hand −
held tester, and read off various data output from
the vehicle’s ECM.
OBD II regulations require that the vehicle’s on −
board computer lights up the Malfunction Indicator
Lamp (MIL) on the instrument panel when the com-
puter detects a malfunction in the computer itself or
in drive system components which affect vehicle
emissions. In addition to the MIL lighting up when
a malfunction is detected, the applicable Diagnostic
Trouble Codes (DTC) prescribed by SAE J2012 are
recorded in the ECM memory (See page DI−13).
If the malfunction does not reoccur in 3 trips, the MIL goes off
but the DTC remain recorded in the ECM memory.
To check the DTC, connect the OBD II scan tool or
TOYOTA hand−held tester to Data Link Connector
3 (DLC3) on the vehicle. The OBD II scan tool or
TOYOTA hand−held tester also enables you to
erase the DTCs and check freezed frame data and
various forms of engine data (For operating instruc-
tions, see the OBD II scan tool’s instruction book.).
DTC include SAE controlled codes and manufac-
turer controlled codes. SAE controlled codes must
be set as prescribed by the SAE, while manufactur-
er controlled codes can be set freely by the
manufacturer within the prescribed limits (See DTC
chart on page DI−13).

DTC P1780 Park/Neutral Position Switch Malfunction
CIRCUIT DESCRIPTION
The park/neutral position switch goes on when the shift lever is in the N o\
r P shift position. When it goes on
terminal NSW of the ECM is grounded to body ground via the starter relay, thus the terminal NSW voltage
becomes 0 V. When the shift lever is in the D, 2, L or R position, the park/neutral\
position switch goes off,
so the voltage of ECM, terminal NSW becomes battery voltage, the voltage of the ECM internal power
source. If the shift lever is moved from the N position to the D position, this signal is used for air\
−fuel ratio
correction and for idle speed control (estimated control), etc.

SAE controlled codes must be set as prescribed by
the SAE, while Manufacturer controlled codes can
be set freely by the manufacturer within the pre-
scribed limits (See page DI−143).

(3) With the engine OFF, add new fluid through the oil
filler pipe.
Fluid type: ATF DEXRON ®II
Capacity:
Dry fill: 11.0 liters (11.6 US qts, 9.7 Imp. qts)
Drain and refill: 1.9 liters (2.0 US qts, 1.7 Imp. qts)
(4) Start the engine and shift the shift lever into all posi-
tions from P to L position and then shift into P posi-
tion.
(5) With the engine idling, check the fluid level. Add fluid up to the COOL level on the dipstick.
(6) Check the fluid level at the normal operating tem- perature 70 − 80° C (158 − 176°F) and add as nec-
essary.
NOTICE:
Do not overfill.
(d) Check the fluid leaks.
Check for leaks in the transmission.
If there are leaks, it is necessary to repair or replace O −rings,
Seal packings, oil seals, plugs or other parts.
(e) Inspect and adjust the throttle cable. (1) Check that the throttle valve is fully closed.
(2) Check that the inner cable is not slack.
(3) Measure the distance between the outer cable endand stopper on the cable.
Standard distance: 0 − 1 mm (0 − 0.04 in.)
If the distance is not standard, adjust the cable by the adjusting
nuts.
(f) Inspect and adjust the shift lever position. When shifting the shift lever from the N position to other
positions, check that the lever can be shifted smoothly
and accurately to each position and that the position indi-
cator correctly indicates the position.
If the indicator is not aligned with the correct position, carry out
the following adjustment procedures. (1) Loosen the nut on the control rod.
(2) Push the control rod fully rearward.

PROBLEM SYMPTOMS TABLE
If a normal code is displayed during the diagnostic trouble code check but\
the trouble still occurs, check the
circuits for each symptom in the order given in the charts on the following pages and\
proceed to the page
given for troubleshooting.
The Matrix Chart is divided into 3 chapters.
Chapter 1: Electronic Circuit Matrix Chart
Chapter 2: On−Vehicle repair Matrix Chart
Chapter 3: Off−Vehicle repair Matrix Chart
When troubleshooting, check Chapter 1 first. If instructions are given i\
n Chapter 1 to proceed to chapter 2
or 3, proceed as instructed.
(1) If the instruction ”Proceed to next circuit inspection shown on matrix chart” is given in the flow
chart for each circuit, proceed to the circuit with the next highest number in the table to cont\
inue
the check.
(2) If the trouble still occurs even though there are no abnormalities in any\
of the other circuits, then check and replace the ECM.
