INSPECTION PROCEDURE
HINT:
Read freeze frame data usingthe hand−held tester.Freeze frame data records the engine conditions 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.
1CHECK OPERATION OF SPEEDOMETER
(a) Drive the vehicle and check if the operation of the speedometer in the combination meter is normal.
HINT:
The vehicle speed sensor is operating normally if the speedometer display is normal.
NG CHECK SPEEDOMETER CIRCUIT (INCLUDE
SPEED SENSOR)

2 READ VALUE OF HAND −HELD TESTER(VEHICLE SPEED)
(a) Connect the hand −held tester to the DLC3.
(b) Turn the ignition switch to ON and turn the hand −held tester ON.
(c) Start the engine.
(d) Select the item ”DIAGNOSIS / OBD/MOBD / DATA LIST / ALL / VEHICLE SPD”.
(e) Check the vehicle speed at the engine speed of 2,000 rpm or more when the vehicle is running. Standard: Same value as the actual vehicle speed.
YES CHECK FOR INTERMITTENT PROBLEMS(See page 05 −270)
NO
3 INSPECT ECM(SP 1 VOLTAGE)
(a) Shift the transmission gear selector lever to the neutral
position.
(b) Jack up the vehicle.
(c) Turn the ignition switch to ON.
(d) Check the voltage between the specified terminals of the E10 and E13 ECM connectors as the wheel is turned
slowly.
Standard:
Tester ConnectionSpecified Condition
SPD (E10 −17) − E2 (E13 −28)Generated intermittently
HINT:
The output voltage should fluctuate up and down similarly to the
diagram on the left when the wheel is turned slowly.
NG REPAIR OR REPLACE HARNESS OR CONNECTOR

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.
1 CHECK OTHER DTC OUTPUT(IN ADDITION TO DTC P0380)
(a) Connect the hand −held tester to the DLC3.

KICK DOWN SWITCH CIRCUIT
CIRCUIT DESCRIPTION
The kick−down switch is turned ON when the accelerator pedal is fully depressed and a signal is sent to the
ECM.
When the kick−down switch is turned ON, the ECM controls gear shifting according to the programmed shift
diagrams.
If a short circuit develops in the kick−down switch, the ECM disregards the kick−down signals and controls
shifting at the normal shift points.
