DIAGNOSTIC FUNCTION
 
 
 
 
MALFUNCTION INDICATOR LAMP (SERVICE ENGINE SOON OR CHECK ENGINE LAMP)
Among the on-board diagnostic items, Malfunction Indicator Lamp (SERVICE ENGINE SOON or Check Engine Lamp) illuminates to notify the driver of an emission control malfunction.
However, when an irregular signal returns to normal and the engine control module judges that it has returned to normal, the Malfunction Indicator Lamp (SERVICE ENGINE SOON or Check Engine Lamp) will switch off.
When the ignition switch is in the ON position, the indicator lamp should be illuminated. When the engine starts, the indicator lamp should be extinguished.

noteIf the Malfunction Indicator Lamp (SERVICE ENGINE SOON or Check Engine Lamp) illuminates because of a malfunction of the engine control module (ECM), communication between the scan tool (M.U.T.-IIISE) and the ECM is impossible. In this case, the diagnostic trouble code cannot be read.
noteAfter the ECM has detected a malfunction, the Malfunction Indicator Lamp (SERVICE ENGINE SOON or Check Engine Lamp) illuminates when the engine is next turned on and the same malfunction is re-detected. However, for items marked with a "*1" in the DTC NO. column, the Malfunction Indicator Lamp (SERVICE ENGINE SOON or Check Engine Lamp) illuminates only on the first detection of the malfunction.
noteThe codes marked with a "*2" in the diagnostic trouble code number column have the following two conditions for illuminating the Malfunction Indicator Lamp (SERVICE ENGINE SOON or Check Engine Lamp).
  • In case that the misfire causing the damaged catalyst is detected, the Malfunction Indicator Lamp (SERVICE ENGINE SOON or Check Engine Lamp) will flash until the condition is corrected. If the system detects the same malfunction after the next engine start, and then the condition is corrected, the Malfunction Indicator Lamp (SERVICE ENGINE SOON or Check Engine Lamp) will illuminate.
  • In case that the misfire deteriorating the exhaust gas is detected, the Malfunction Indicator Lamp (SERVICE ENGINE SOON or Check Engine Lamp) is illuminated when the same malfunction is redetected after the next engine start.
noteEven if the malfunction is not detected when the ECM monitors the malfunction three consecutive times* after the Malfunction Indicator Lamp (SERVICE ENGINE SOON or Check Engine Lamp) illuminates, turn off the Malfunction Indicator Lamp (SERVICE ENGINE SOON or Check Engine Lamp) when the engine starts next time.
  • *: In this case, "one time" in monitoring the malfunction means the period from the time of the current engine start to the time of the next engine start. "One time" in monitoring the misfire or the fuel system malfunction means the time when the operating conditions (such as the engine speed or the engine coolant temperature) becomes similar operating conditions of the first detected malfunction.

If detecting the malfunction during the first drive cycle, the ECM temporarily sets the diagnostic trouble code as the provisional diagnostic trouble code. If detecting the same malfunction during the next drive cycle, the ECM determines that the malfunction exists. The ECM sets the diagnostic trouble code. On scan tool (M.U.T.-IIISE), it is possible to display the set provisional diagnostic trouble code which the ECM had detected during the first drive cycle. This makes it possible to confirm in one drive cycle whether the malfunction could happen again after the repair.

5. Select "Special Function" from MFI Screen.
6. Select "Provisional DTCs" from Special Function Screen.
 
 
 
 
PERMANENT DTC
The permanent DTC(PDTC) is set in the EEPROM of the engine control module (ECM) as the permanent status, which checks that the malfunction of the emission related components/ the system has not been repaired yet. When detecting the malfunction necessary to illuminate the malfunction indicator lamp (SERVICE ENGINE SOON or Check Engine Lamp), the ECM illuminates the MIL and sets the appropriate DTC as the permanent DTC in the EEPROM concurrently. The ECM can store up to 6 PDTCs. The ECM, therefore, cannot store the 7th and subsequent PDTCs. If the temporary malfunction causes the malfunction indicator lamp to be illuminated and then the reinstatement during the subsequent driving causes it to be extinguished, the PDTC is erased. Also if the ECM checks that the DTC malfunction is fixed during the driving after the DTC repair is completed, the PDTC is erased. The permanent DTC, however, is not erased by disconnecting the battery terminal or erasing with the scan tool (M.U.T.-IIISE). The permanent DTC can be erased if all readiness status are erased or not completed at the time of reprogramming the ECM. If the vehicle is repaired, the PDTC can be erased by the procedures shown below. The permanent DTC need to be erased to pass the Inspection and Maintenance (I/M) test.
 
 
PROCEDURES FOR ERASING PERMANENT DTC
1. Check that the DTC is not set. If the DTC is set, perform the DTC troubleshooting, then repair the DTC.
2. Drive the vehicle in the drive cycle pattern suitable for the permanent DTC. (Refer to OBD-II DRIVE CYCLE for the drive cycle pattern.)
3. Check that the permanent DTC is erased. If the permanent DTC is not erased, check the DTC or the provisional DTC. If the malfunction code is set, repair the DTC. Try to erase the permanent DTC again (from Step 1 to 2). If the malfunction code is not set, the drive cycle pattern (Step 2) monitoring the malfunction can possibly be insufficient.

noteWhen not finishing the monitor of the driving cycle for the request of On-Board Monitoring Test Request, the ECM outputs the stored latest monitor test result.
noteWhen the monitored test results are erased by the battery disconnection and so on, the ECM outputs the values in hexadecimal of "0000" or "FFFF", otherwise it outputs abnormal values and so on. In case of this, the ECU outputs are handled as invalid-values. When the first monitor (Readiness Status) is completed after this, the ECM outputs the valid-values.
note"Test Limit Type & Component ID byte" output from the ECM is given in hexadecimal of "00" or "80". "00" means the maximum value and "80" means the minimum value.
 
 
ON-BOARD DIAGNOSTICS
The engine control module (ECM) monitors the input/output signals (some signals all the time and others under specified conditions) of the ECM. When a malfunction continues for a specified time or longer after the irregular signal is initially monitored, the ECM judges that a malfunction has occurred. After the ECM first detects a malfunction, a diagnostic trouble code is recorded when the engine is restarted and the same malfunction is re-detected. However, for items marked with a "*", a diagnostic trouble code is recorded on the first detection of the malfunction. The diagnostic results can be read out with a scan tool. Since memorization of the diagnostic trouble codes is backed up directly by the battery, the diagnostic results are memorized even if the ignition key is turned off. The diagnostic trouble codes will, however, be erased when the battery terminal or the ECM connector is disconnected. In addition, the diagnostic trouble code can also be erased by turning the ignition switch to ON and sending the diagnostic trouble code erase signal from scan tool (M.U.T.-IIISE) to the ECM.
note If the sensor connector is disconnected with the ignition switch turned on, the diagnostic trouble code is memorized. In this case, send the diagnostic trouble code erase signal to the ECM in order to erase the diagnostic memory. The diagnostic items are all indicated sequentially from the smallest code number. The ECM records the engine operating condition when the diagnostic trouble code is set. This data is called "Freeze-frame" data. This data can be read by using the scan tool, and can then be used in simulation tests for troubleshooting. Data items are as follows:
noteIf the ECM detects multiple malfunctions, the ECM stores the "Freeze-frame" data for only the first item that was detected. However, if the ECM detects a misfire or a fuel system malfunction, the ECM stores the data by giving priority to the misfire or fuel system malfunction, regardless of the order in which the malfunction was detected.
noteAs for Diagnostic trouble code P1603, "Freeze-frame" data is not memorized.

OBD- II DRIVE CYCLE
All kinds of diagnostic trouble codes (DTCs) can be monitored by carrying out a short drive according to the following 18 drive cycle patterns. In other words, doing such a drive regenerates any kind of trouble which involves illuminating the Malfunction Indicator Lamp (SERVICE ENGINE SOON or Check Engine Lamp) and verifies the DTC malfunction is fixed [the Malfunction Indicator Lamp (SERVICE ENGINE SOON or Check Engine Lamp) is no longer illuminated].
caution
  • Two technicians should always be in the vehicle when carrying out a test.
  • Perform the pattern of the trouble check at least two times.
  • Do not lack the safety in patterns with high vehicle speed and high load operation.
note
  • Check that the diagnosis trouble code (DTC) is not set before driving the OBD-II drive cycle. Erase the DTC with scan tool (M.U.T.-IIISE) if it has been set.
  • For P0461 and P2066, please reference the M.U.T.-IIISE data list to judge whether these monitor items are normal.

SYSTEM READINESS TEST STATUS
 
 
PURPOSE
The Readiness function (also referred to as I/M Readiness or I/M Flags) indicates if a full diagnostic check has been "Completed" (is "Ready") for each non-continuous monitor. Enhanced I/M State Emission Programs will use the Readiness status (Codes) to see if the vehicle is ready for OBD-II testing. "Incomplete" (Not Ready) codes will be one of the triggers for I/M failure.
 
 
OVERVIEW
The ECM monitors the following main diagnosis items and records whether the evaluation was completed or is incomplete. The Readiness Codes are established for the I/M programs, thereby confirming that the vehicles have not been tampered with by erasing the diagnostic trouble code(s) (DTCs) before I/M testing. The Readiness Codes and DTCs can be set again by disconnecting the battery or by erasing the codes with a scan tool (M.U.T.-IIISE). For this reason, all the Readiness Codes must be displayed "Complete" before I/M testing.
When the monitors run and complete, the scan tool (M.U.T.-IIISE) will display the Readiness Codes as "Complete" (General Scan Tools display as "Ready"). When the vehicle is operating normally and the OBD-II Drive Cycle is carried out, the Readiness Codes will be generated as "Complete" on the first drive cycle. For DTCs requiring two drive cycles to detect a fault, the second drive cycle is required to generate the Readiness Codes as "Complete" if a fault is detected during the first drive cycle. If the fault is still there after the second drive cycle, a DTC will be set.
  • Catalyst: P0421
  • Evaporative system: P0442, P0455, P0456
  • Linear air-fuel ratio sensor: P0133
  • Linear air-fuel ratio sensor <From 19 Model year>: P014C, P014D, P015A, P015B
  • Linear air-fuel ratio sensor heater: P0031, P0032, P0053
  • Heated oxygen sensor (rear): P0139, P0140
  • Heated oxygen sensor (rear) heater: P0037, P0038
  • VVT system: P0011, P0014
After all the Readiness Codes are displayed as "Complete", the technician is assured that any DTCs related to the monitor will be displayed if the system has a problem. That is why some State's I/M programs require the Readiness Code as "Complete" before they check for DTCs.
noteAfter a repair is made for a DTC, the technician should drive the OBD-II Drive Cycle checking that the scan tool (M.U.T.-IIISE) displays all the Readiness Codes as "Complete".
