3. INSPECT DIAGNOSIS (CHECK MODE)
HINT:
Hand±held tester only:
Compared to the normal mode, the check mode has high sens-
ing ability to detect malfunctions.
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 voltage 11 V or more
Throttle valve fully closed
Shift lever in P range
Air conditioning switched OFF
(2) Turn the ignition switch OFF.
(3) Prepare the hand±held tester.
(4) Connect the hand±held tester to DLC3.
(5) Turn the ignition switch ON and switch the hand±
held tester ON.
(6) Switch the 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
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, which all DTCs etc. are erased.
(10) After checking the DTC, inspect the applicable cir-
cuit.
(b) Clear the DTC.
(1) When using hand±held tester:
The following operation will erase the DTC and
freeze frame data. Operate a hand±held tester to
erase the codes.
(2) When not using the hand±held tester:
Remove the EFI fuse from engine room J/B for 10
seconds or more.

(b)Check the DTC, using the hand±held tester.
NOTICE:
Hand±held tester only:
When the diagnostic system is switched from normal mode
to check (test) mode, it erases all DTCs and freeze frame
data recorded in normal mode. So before switching modes,
always check the DTCs and freeze frame data, and note
them down. (1)Use the hand±held tester to check the DTCs andinstructions, see the hand±held tester instruction
book.
(2)See page 05±931 to confirm the details of the
DTCs.
(c) Clear the DTC. (1) When using the hand±held tester:The following operation will erase the DTC and
freeze frame data. Operate the hand±held tester to
erase the codes.
(2) When not using the hand±held tester: Remove the EFI fuse from engine room J/B for 60
seconds or more.
3. INSPECT DIAGNOSIS (CHECK MODE)
HINT:
Hand±held tester only:
Compared to the normal mode, the check mode has high sens-
ing ability to detect malfunctions.
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.

(4) Connect the hand±held tester to DLC3.
(5) Turn the ignition switch ON and switch the hand± held tester ON.
(6) Switch the hand±held tester from Normal mode to Check mode (Check that the MIL flashes).
NOTICE:
If the hand±held tester switches the ECM from the normal
mode to the check mode or vice±versa, or if the ignition
switch is turned from ON to ACC or OFF during the check
mode, the DTC and freeze frame data will be erased.
(7) Start the engine (MIL goes out after the enginestarts).
