INSPECTION PROCEDURE
1 Check vehicle speed value or resistance between terminals SP2+ and SP2− of
ECM.
When using OBD II scan tool or TOYOTA hand−held tester:
PREPARATION:
(a) Connect an OBD II scan tool or TOYOTA hand−held tes-
ter to the DLC3.
(b) Start the engine and OBD II scan tool or TOYOTA hand−
held tester main switch ON.
CHECK:
Drive the vehicle and read vehicle speed value.
OK:
Vehicle speed matches tester speed value.
When not using OBD II scan tool or TOYOTA hand−held tes-
ter:
PREPARATION:
Disconnect the connector from the ECM.
CHECK:
Check resistance between terminals SP2+ and SP2− of ECM.
OK:
Resistance: 560 − 680 Ω
OK Check and replace ECM.

2 Check No.2 vehicle speed sensor.
PREPARATION:
Remove the No.2 vehicle speed sensor from the transmission.
CHECK:
(a) Measure resistance between terminals 1 and 2 of vehicle
speed sensor.
(b) Check voltage between terminals 1 and 2 of vehicle
speed sensor when a magnet is put close to the front end
of the vehicle speed sensor then taken away quickly.
OK:
(a) Resistance: 560 − 680 Ω
(b) Voltage is generated intermittently.
HINT:
The voltage generated is extremely low.
NG Replace No.2 vehicle speed sensor.
OK
Check and repair the harness and connector
between ECM and No.2 vehicle speed
sensor (See page IN−26).

INSPECTION PROCEDURE
1 Read PNP, REVERSE, 2ND and LOW signals.
When using TOYOTA hand−held tester:
PREPARATION:
(a) Connect a TOYOTA hand−held tester to the DLC3.
(b) Turn the ignition switch ON and TOYOTA hand−held tes-
ter main switch ON.
CHECK:
Shift lever into the P, R, N, 2 and L positions, and read the PNP,
REVERSE, 2ND and LOW signals on the TOYOTA hand−held
