3. INSPECT DIAGNOSIS (CHECK MODE)
HINT:
TOYOTA hand±held tester only: Compared to the normal
mode, the check mode has high sensing ability to detect mal-
functions. Furthermore, the same diagnostic items which are
detected in Normal mode can also be detected in Check mode.
(a) Check the DTC.
(1) Check the initial conditions.

Battery positive voltage 11 V or more.

Throttle valve fully closed.

Transaxle in P position.

Air conditioning switched off.
(2) Turn the ignition switch OFF.
(3) Prepare a TOYOTA hand±held tester.
(4) Connect the TOYOTA hand±held tester to DLC3 at
the lower of the instrument panel.
(5) Turn the ignition switch ON and switch the TOYOTA
hand±held tester ON.
(6) Switch the TOYOTA hand±held tester from Normal
mode to Check mode (Check that the MIL flashes).
(7) Start the engine (MIL goes out after the engine
starts).
(8) Simulate the conditions of the malfunction de-
scribed by the customer.
NOTICE:
Leave the ignition switch ON until you have checked the
DTCs, etc..
(9) After simulating the malfunction conditions, use the
TOYOTA hand±held tester diagnosis selector to
check the DTCs and freeze frame data, etc..
HINT:
Take care not to turn the ignition switch OFF, as turning it off
switches the diagnosis system from Check mode to Normal
mode, so all DTCs, etc. are erased.
(10) After checking the DTC, inspect the applicable cir-
cuit.
