IIf MI illuminates or flashes irregularly while the engine is
running, water may have accumulated in fuel filter. Drain
water from fuel filter. If this does not correct the problem,
perform specified trouble diagnostic procedures.
IAfter performing each TROUBLE DIAGNOSIS, perform
ªOVERALL FUNCTION CHECKº or ªDTC (Diagnostic
Trouble Code) CONFIRMATION PROCEDUREº.
The DTC should not be displayed in the ªDTC CONFIRMA-
TION PROCEDUREº if the repair is successful. The ªOVER-
ALL FUNCTION CHECKº should indicate a good result if
the repair is completed successfully.
IWhen measuring ECM signals with a circuit tester, never
allow the two tester probes to contact.
Accidental contact of probes will cause a short circuit and
damage the ECM power transistor.

PRECAUTIONS AND PREPARATIONTD27Ti
Precautions (Cont'd)
EC-299

DTC and MI Detection Logic
When a malfunction is detected for the first time, the malfunction (DTC) is stored in the ECM memory.
The MI will light up each time the ECM detects a malfunction. However, if the same malfunction is experienced
in two consecutive driving patterns and the engine is still running, the MI will stay lit up. For a description of
diagnostic items causing the MI to light up, refer to ªTROUBLE DIAGNOSIS Ð INDEXº, EC-293.
Diagnostic Trouble Code (DTC)
HOW TO READ DTC
The DTC can be read by the following methods.
Without CONSULT-II
ECM displays the DTC by a set of four digit numbers with MI illumination in the diagnostic test mode II (Self-
diagnostic results). Example: 0102, 0103, 0104, etc.
With CONSULT-II
CONSULT-II displays the DTC in ªSELF-DIAG RESULTSº mode. Examples: P0100, P0115, P0500, etc.
These DTCs are prescribed by ISO15031-6.
(CONSULT-II also displays the malfunctioning component or system.)
IOutput of the trouble code means that the indicated circuit has a malfunction. However, in the Mode
II it does not indicate whether the malfunction is still occurring or occurred in the past and returned
to normal.
CONSULT-II can identify them. Therefore, using CONSULT-II (if available) is recommended.
HOW TO ERASE DTC
How to Erase DTC (
With CONSULT-II)
1. If the ignition switch stays ªONº after repair work, be sure to turn ignition switch ªOFFº once. Wait at least
5 seconds and then turn it ªONº (engine stopped) again.
2. Touch ªENGINEº.
3. Touch ªSELF-DIAG RESULTSº.
4. Touch ªERASEº. (The DTC in the ECM will be erased.)
The emission related diagnostic information in the ECM can be erased by selecting ªERASEº in the ªSELF-
DIAG RESULTSº mode with CONSULT-II.
