CHECK MODE PROCEDURE
HINT:
Hand−held tester only:
Check mode has a higher sensitivity to detect malfunctions and
can detect malfunctions that normal mode cannot detect.
Check mode can also detect all the malfunctions that normal
mode can detect.
1. CHECK MODE PROCEDURE(Using the hand−held
tester)
(a) Turn the ignition switch to OFF.
(b) Connect the hand−held tester to the DLC3.
(c) Turn the ignition switch to ON and turn the hand−held tes-
ter ON.
(d) Select the item: DIAGNOSIS / OBD/MOBD / CHECK
MODE.
NOTICE:
All DTCs and freeze frame data recorded will be erased if:
1) the hand−held tester is used to change the ECM from
normal mode to check mode or vice versa; or 2) during
check mode, the ignition switch is turned from ON to ACC
or OFF.
(e) Start the engine. The CHK ENG should turn off after the
engine starts.
(f) Simulate condition of the malfunction described by the
customer or freeze frame data.
(g) After simulating the malfunction condition, use the hand−
held tester diagnosis selector to check the DTCs, freeze
frame data and other data.
(h) After checking the DTCs, inspect the applicable parts.
2. CLEAR DTCs (Using the hand−held tester)
(a) Connect the hand−held tester to the DLC3.
(b) Turn the ignition switch to ON and turn the hand−held tes-
ter ON. (Do not start the engine)
(c) Select the item: DIAGNOSIS / OBD/MOBD / DTC INFO
/ CLEAR CODES.
(d) Clear DTCs and freeze frame data.
HINT:
If you need help with the hand−held tester, refer to its instruction
book.
(e) Disconnect the battery terminal or remove the ECD fuse
from the engine room R/B for more than 60 seconds.

CIRCUIT DESCRIPTION
HINT:
While the engine is being cranked, current flows from terminal ST2 of the ignition switch to the ST relay coil
and also current flows to terminal STA of the ECM (STA signal).
