2. INSPECT DIAGNOSIS (NORMAL MODE)
(a) Check the MIL.
(1) The MIL comes on when the ignition switch is turned
ON and the engine is not running.
HINT:
If the MIL does not light up, troubleshoot the combination meter
(See page BE-2).
(2) When the engine is started, the MIL should go off.
If the lamp remains on, the diagnosis system has
detected a malfunction or abnormality in the sys-
tem.
(b) Check the DTC.
NOTICE:
TOYOTA hand-held tester only:
When the diagnostic system is switched from normal mode
to check mode, it erases all DTCs and freeze frame data re-
corded in normal mode. So before switching modes, al-
ways check the DTCs and freeze frame data, and note them
down.
(1) Prepare an OBD II scan tool (complying with SAE
J1978) or TOYOTA hand-held tester.
(2) Connect the OBD II scan tool or TOYOTA hand-
held tester to DLC3 at the lower of the instrument
panel.
(3) Turn the ignition switch ON and turn the OBD II scan
tool or TOYOTA hand-held tester switch ON.
(4) Use the OBD II scan tool or TOYOTA hand-held
tester to check the DTCs and freeze frame data and
note them down (For operating instructions, see the
OBD II scan tool's instruction book).
(5) See page DI-172 to confirm the details of the DTCs.
NOTICE:
When simulating symptoms with an OBD II scan tool (ex-
cluding TOYOTA hand-held tester) to check the DTCs, use
normal mode. For codes on the DTCs chart subject to
º2-trip detection logicº, turn the ignition switch OFF after
the symptoms have been simulated the 1st time. Then re-
peat the simulation process again. When the program has
DTCs they are recorded in the ECM.

DTC 21 Open in Vehicle Speed Sensor Circuit
CIRCUIT DESCRIPTION
The signal from the vehicle speed sensor circuit is sent to cruise control ECU as vehicle speed signal.
The rotor shaft is driven by the gear of the transmission.
For each rotation of the shaft, the vehicle speed sensor sends a 4-pulse signal through the combination
meter to the cruise control ECU (See the following installation).
This signal is converted inside the combination meter and sent as a 4-pulse signal to the cruise control ECU.
The ECU calculates the vehicle speed from this pulse frequency.
DTC No.Detection ItemTrouble Area
21Speed signal is not input to the cruise control ECU while cruise
control is set.
