(6) *2 trip detection logic:
When a malfunction is first detected, the malfunc-
tion code is temporarily stored in the ECM memory
(1st trip). If the same malfunction is detected again
during the second drive test, this second detection
causes the CHK ENG (MIL) to illumenate (2nd trip)
(However, the ignition switch must be turned OFF
between the 1st trip and the 2nd trip.).
(b) Inspect the DLC3.
(1) The vehicle's ECM uses ISO 9141±2 (Euro±OBD)
communication protocol. The terminal arrangement
of DLC3 complies with ISO 15031±3 and matches
the ISO 9141±2 format.

HINT:
If your display shows ºUNABLE TO CONNECT TO VEHICLEº
when you have connected the cable of hand±held tester to
DLC3, turned the ignition switch ON and operated the hand±
held tester, there is a problem on the vehicle side or tool side.
If communication is normal when the tool is connected to
another vehicle, inspect DLC3 on the original vehicle.
If communication is still not possible when the tool is con-
nected to another vehicle, the problem is probably in the
tool itself, so consult the Service Department listed in the
tool's instruction manual.
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 come on, troubleshoot the combination me-
ter.
(2) When the engine is started, the MIL should go off.
If the light remains on, the diagnosis system has de-
tected a malfunction or abnormality in the system.
