ON BOARD DIAGNOSIS ITEM
The on board diagnostic system has the following functions.
Diagnostic test mode | Function |
Bulb check | MIL can be checked. |
SRT status | ECM can read if SRT codes are set. |
Malfunction warning | If ECM detects a malfunction, it illuminates or blinks MIL to inform the driver that a malfunction has been detected. |
Self-diagnostic results | DTCs or 1st trip DTCs stored in ECM can be read. |
Accelerator pedal released position learning | ECM can learn the accelerator pedal released position. Refer to EC-138, "Work Procedure". |
Throttle valve closed position learning | ECM can learn the throttle valve closed position. Refer to EC-139, "Work Procedure". |
Idle air volume learning | ECM can learn the idle air volume. Refer to EC-140, "Work Procedure". |
Mixture ratio self-learning value clear | Mixture ratio self-learning value can be erased. Refer to EC-142, "Work Procedure". |
BULB CHECK MODE
Description
This function allows damage inspection in the MIL bulb (blown, open circuit, etc.).
Operation Procedure
If it remains OFF, check MIL circuit. Refer to EC-467, "Diagnosis Procedure".
SRT STATUS MODE
Description
This function allows to read if ECM has completed the self-diagnoses of major emission control systems and components. For SRT, refer to EC-61, "DIAGNOSIS DESCRIPTION : System Readiness Test (SRT) Code".
Operation Procedure
MALFUNCTION WARNING MODE
Description
In this function ECM turns on or blinks MIL when it detects a malfunction in the emission control system components and/or the powertrain control components (which affect vehicle emissions) to inform the driver that a malfunction has been detected.
Operation Procedure
If it remains OFF, check MIL circuit. Refer to EC-61, "DIAGNOSIS DESCRIPTION : System Readiness Test (SRT) Code".
SELF-DIAGNOSTIC RESULTS MODE
Description
This function allows to indicate DTCs or 1st trip DTCs stored in ECM according to the number of times MIL is blinking.
How to Set Self-diagnostic Results Mode
NOTE:
NOTE:
Do not release the accelerator pedal for 10 seconds if MIL starts blinking during this period. This blinking is displaying SRT status and is continued for another 10 seconds.
ECM has entered to “Self-diagnostic results” mode.
NOTE:
Wait until the same DTC (or 1st trip DTC) appears to completely confirm all DTCs.
How to Read Self-diagnostic Results
The DTC and 1st trip DTC are indicated by the number of blinks of the MIL as shown below.
The DTC and 1st trip DTC are displayed at the same time. If the MIL does not illuminate in diagnostic test mode I (Malfunction warning), all displayed items are 1st trip DTCs. If only one code is displayed when the MIL illuminates in “malfunction warning” mode, it is a DTC; if two or more codes are displayed, they may be either DTCs or 1st trip DTCs. DTC No. is same as that of 1st trip DTC. These unidentified codes can be identified by using the CONSULT or GST. A DTC will be used as an example for how to read a code.
A particular trouble code can be identified by the number of four-digit numeral flashes per the following.
The length of time the 1,000th-digit numeral flashes on and off is 1.2 seconds consisting of an ON (0.6-seconds) - OFF (0.6-seconds) cycle.
The 100th-digit numeral and lower digit numerals consist of a 0.3-seconds ON and 0.3-seconds OFF cycle.
A change from one digit numeral to another occurs at an interval of 1.0-second OFF. In other words, the later numeral appears on the display 1.3 seconds after the former numeral has disappeared.
A change from one trouble code to another occurs at an interval of 1.8-seconds OFF.
In this way, all the detected malfunctions are classified by their DTC numbers. The DTC 0000 refers to no malfunction.
Refer to EC-94, "DTC Index".
How to Erase Self-diagnostic Results
By performing this procedure, ECM memory is erased and the following diagnostic information is erased as well.
NOTE:
Also, if a battery terminal is disconnected, ECM memory is erased and the diagnostic information as listed above is erased. (The amount of time required for erasing may vary from a few seconds to several hours.)
Fully depress the accelerator pedal and keep it depressed for more than 10 seconds.
