On Board Diagnostic (OBD) System of Engine and CVT

The ECM has an on board diagnostic system. It will light up the malfunction indicator (MI) to warn the driver of a malfunction causing emission deterioration.

CAUTIONBe sure to turn the ignition switch OFF and disconnect the negative battery cable before any repair or inspection work. The open/short circuit of related switches, sensors, solenoid valves, etc. will cause the MI to light up. Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will cause the MI to light up due to the open circuit. (Be sure the connector is free from water, grease, dirt, bent terminals, etc.) Certain systems and components, especially those related to OBD, may use a new style slide-locking type harness connector. For description and how to disconnect, refer to " DESCRIPTION ". Be sure to route and secure the harnesses properly after work. The interference of the harness with a bracket, etc. may cause the MI to light up due to the short circuit. Be sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube may cause the MI to light up due to the malfunction of the fuel injection system, etc. Be sure to erase the unnecessary malfunction information (repairs completed) from the ECM and TCM (Transmission control module) before returning the vehicle to the customer.

  1. Always use a 12 volt battery as power source.
  2. Do not attempt to disconnect battery cables while engine is running.
  3. Before connecting or disconnecting the ECM harness connector, turn ignition switch OFF and disconnect negative battery cable. Failure to do so may damage the ECM because battery voltage is applied to ECM even if ignition switch is turned OFF.
  4. Before removing parts, turn ignition switch OFF and then disconnect battery ground cable.
  5. Do not disassemble ECM.
  6. If a battery cable is disconnected, the memory will return to the ECM value. The ECM will now start to self-control at its initial value. So, engine operation can vary slightly in this case. However, this is not an indication of a malfunction. Do not replace parts because of a slight variation.
  7. If the battery is disconnected, the following emission-related diagnostic information will be lost within 24 hours. Diagnostic trouble codes 1st trip diagnostic trouble codes Freeze frame data 1st trip freeze frame data System readiness test (SRT) codes Test values

  1. When connecting or disconnecting pin connectors into or from ECM, take care not to damage pin terminals (bend or break). Make sure that there are not any bends or breaks on ECM pin terminal, when connecting pin connectors.
  2. Securely connect ECM harness connectors. A poor connection can cause an extremely high (surge) voltage to develop in coil and condenser, thus resulting in damage to ICs.
  3. Keep engine control system harness at least 10 cm (4 in) away from adjacent harness, to prevent engine control system malfunctions due to receiving external noise, degraded operation of ICs, etc.
  4. Keep engine control system parts and harness dry.
  5. Before replacing ECM, perform ECM Terminals and Reference Value inspection and make sure ECM functions properly. Refer to " «REFERENCE VALUE»(ref-605934-S39096177382014032500000) ".
  6. Handle mass air flow sensor carefully to avoid damage.
  7. Do not clean mass air flow sensor with any type of detergent.
  8. Do not disassemble electric throttle control actuator.
  9. Even a slight leak in the air intake system can cause serious incidents.
  10. Do not shock or jar the camshaft position sensor (PHASE), crankshaft position sensor (POS).
  11. After performing each TROUBLE DIAGNOSIS, perform DTC CONFIRMATION PROCEDURE or Component Function Check. The DTC should not be displayed in the DTC Confirmation Procedure if the repair is completed. The Component Function Check should be a good result if the repair is completed.
  12. When 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.
  13. Do not operate fuel pump when there is no fuel in lines.
  14. Tighten fuel hose clamps to the specified torque.
  15. Do not depress accelerator pedal when starting.
  16. Immediately after starting, do not rev up engine unnecessarily.
  17. Do not rev up engine just prior to shutdown.
  18. When installing C.B. ham radio or a mobile phone, be sure to observe the following as it may adversely affect electronic control systems depending on installation location. Keep the antenna as far as possible from the electronic control units. Keep the antenna feeder line more than 20 cm (8 in) away from the harness of electronic controls. Do not let them run parallel for a long distance. Adjust the antenna and feeder line so that the standing-wave ratio can be kept smaller. Be sure to ground the radio to vehicle body.

GST (Generic Scan Tool)

When GST is connected with a data link connector equipped on the vehicle side, it will communicate with the control unit equipped in the vehicle and then enable various kinds of diagnostic tests. Refer to " DIAGNOSIS DESCRIPTION ".

Note. Service $0A is not applied for regions where it is not mandated.

DTC AND 1ST TRIP DTC

The 1st trip DTC (whose number is the same as the DTC number) is displayed for the latest self-diagnostic result obtained. If the ECM memory was cleared previously, and the 1st trip DTC did not recur, the 1st trip DTC will not be displayed.

If a malfunction is detected during the 1st trip, the 1st trip DTC is saved in the ECM memory. The MIL will not light up (two trip detection logic). If the same malfunction is not detected in the 2nd trip (meeting the required driving pattern), the 1st trip DTC is cleared from the ECM memory. If the same malfunction is detected in the 2nd trip, both the 1st trip DTC and DTC are saved in the ECM memory and the MIL lights up. In other words, the DTC is stored in the ECM memory and the MIL lights up when the same malfunction occurs in two consecutive trips. If a 1st trip DTC is stored and a non-diagnostic operation is performed between the 1st and 2nd trips, only the 1st trip DTC will continue to be stored. For malfunctions that blink or light up the MIL during the 1st trip, the DTC and 1st trip DTC are stored in the ECM memory.

For malfunctions in which 1st trip DTCs are displayed, refer to " DTC INDEX ". These items are required by legal regulations to continuously monitor the system/component. In addition, the items monitored non-continuously are also displayed on CONSULT.

1st trip DTC is specified in Service $07 of SAE J1979/ISO 15031-5. 1st trip DTC detection occurs without illuminating the MIL and therefore does not warn the driver of a malfunction.

When a 1st trip DTC is detected, check, print out or write down and erase (1st trip) DTC and Freeze Frame data as specified in Work Flow procedure Step 2, refer to " WORK FLOW ". Then perform DTC Confirmation Procedure or Component Function Check to try to duplicate the malfunction. If the malfunction is duplicated, the item requires repair.

RELATIONSHIP BETWEEN MIL, 1ST TRIP DTC, DTC, AND DETECTABLE ITEMS

  1. When a malfunction is detected for the first time, the 1st trip DTC and the 1st trip freeze frame data are stored in the ECM memory.
  2. When the same malfunction is detected in two consecutive trips, the DTC and the freeze frame data are stored in the ECM memory, and the MIL will come on.
  3. The MIL will turn OFF after the vehicle is driven 3 times (driving pattern B) with no malfunction. The drive is counted only when the recorded driving pattern is met (as stored in the ECM). If another malfunction occurs while counting, the counter will reset.
  4. The DTC and the freeze frame data will be stored until the vehicle is driven 40 times (driving pattern A) without the same malfunction recurring (except for Misfire and Fuel Injection System). For Misfire and Fuel Injection System, the DTC and freeze frame data will be stored until the vehicle is driven 80 times (driving pattern C) without the same malfunction recurring. The "TIME" in "SELF-DIAGNOSTIC RESULTS" mode of CONSULT will count the number of times the vehicle is driven.
  5. The 1st trip DTC is not displayed when the self-diagnosis results in OK for the 2nd trip.

PERMANENT DTC SET TIMING

The setting timing of permanent DTC is stored in ECM with the lighting of MIL when a DTC is confirmed.

ON BOARD DIAGNOSIS ITEM

The on board diagnostic system has the following functions.

Diagnostic test modeFunction
Bulb checkMIL can be checked.
SRT statusECM can read if SRT codes are set.
Malfunction warningIf ECM detects a malfunction, it illuminates or blinks MIL to inform the driver that a malfunction has been detected.
Self-diagnostic resultsDTCs or 1st trip DTCs stored in ECM can be read.
Accelerator pedal released position learningECM can learn the accelerator pedal released position. Refer to " WORK PROCEDURE ".
Throttle valve closed position learningECM can learn the throttle valve closed position. Refer to " WORK PROCEDURE ".
Idle air volume learningECM can learn the idle air volume. Refer to " WORK PROCEDURE ".
Mixture ratio self-learning value clearMixture ratio self-learning value can be erased. Refer to " WORK PROCEDURE ".

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. It is better to count the time accurately with a clock. It is impossible to switch the diagnostic mode when an accelerator pedal position sensor circuit has a malfunction. After ignition switch is turned off, ECM is always released from the "self-diagnostic results" mode.

  1. Confirm that accelerator pedal is fully released, turn ignition switch ON and wait 3 seconds.
  2. Repeat the following procedure quickly five times within 5 seconds. Fully depress the accelerator pedal. Fully release the accelerator pedal.
  3. Wait 7 seconds, fully depress the accelerator pedal and keep it depressed for approx. 10 seconds until the MIL starts blinking. 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.
  4. Fully release the accelerator pedal. 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. Number 0 1 2 3 4 5 6 7 8 9 A B C D E F Flashes 10 1 2 3 4 5 6 7 8 9 11 12 13 14 15 16 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 " «DTC INDEX»(ref-605934-S24886252492014032500000) ". How to Erase Self-diagnostic Results By performing this procedure, ECM memory is erased and the following diagnostic information is erased as well. Diagnostic trouble codes 1st trip diagnostic trouble codes Freeze frame data 1st trip freeze frame data System readiness test (SRT) codes Test values 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.)
  1. Turn ignition switch OFF and wait at least 10 seconds.
  2. Turn ignition switch ON.
  3. Turn ignition switch OFF and wait at least 10 seconds.
  4. Turn ignition switch ON.
  5. Set ECM in "self-diagnostic results" mode.
  6. The diagnostic information has been erased from the backup memory in the ECM. Fully depress the accelerator pedal and keep it depressed for more than 10 seconds.
  7. Fully release the accelerator pedal, and confirm the DTC 0000 is displayed.

SELF DIAGNOSTIC RESULT MODE

Self Diagnostic Item

Regarding items of DTC and 1st trip DTC, refer to " DTC INDEX ".

How to Read DTC and 1st Trip DTC

DTCs and 1st trip DTCs related to the malfunction are displayed in "self-diag results".

  1. When ECM detects a 1st trip DTC, "1t" is displayed for "TIME".
  2. When ECM has detected a current DTC, "0" is displayed for "TIME".
  3. If "TIME" is neither "0" nor "1t", the DTC occurred in the past and ECM shows the number of times the vehicle has been driven since the last detection of the DTC. How to Erase DTC and 1st Trip DTC NOTE: If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once. Wait at least 10 seconds and then turn it ON (engine stopped) again. Select "ENGINE" with CONSULT. Select "SELF-DIAG RESULTS". Touch "ERASE". (DTC in ECM will be erased.) FREEZE FRAME DATA AND 1ST TRIP FREEZE FRAME DATA Freeze frame data item (1) Description Detected DTC The engine control component part/control system has a trouble code, it is displayed as PXXXX.

Note. The following table includes information (items) inapplicable to this vehicle. For information (items) applicable to this vehicle, refer to CONSULT display items.

Remarks

  1. Specification data are reference values.
  2. Specification data are output/input values which are detected or supplied by the ECM at the connector. *Specification data may not be directly related to their components signals/values/operations. i.e. Adjust ignition timing with a timing light before monitoring IGN TIMING, because the monitor may show the specification data in spite of the ignition timing not being adjusted to the specification data. This IGN TIMING monitors the data calculated by the ECM according to the signals input from the camshaft position sensor and other ignition timing related sensors.

Malfunction indicator circuitEngine speed will not rise more than 2, 500 RPM due to the fuel cutWhen there is an open circuit on MIL circuit, the ECM cannot warn the driver by lighting up MIL when there is malfunction on engine control system. Therefore, when electrical controlled throttle and part of ECM related diagnoses are continuously detected as NG for 5 trips, ECM warns the driver that engine control system malfunctions and MIL circuit is open by means of operating fail safe function. The fail safe function also operates when above diagnoses except MIL circuit are detected and demands the driver to repair the malfunction." COMPONENT FUNCTION CHECK "

Test Value and Test Limit

The following is the information specified in Service $06 of SAE J1979/ISO 15031-5.

The test value is a parameter used to determine whether a system/circuit diagnostic test is OK or NG while being monitored by the ECM during self-diagnosis. The test limit is a reference value which is specified as the maximum or minimum value and is compared with the test value being monitored.

These data (test value and test limit) are specified by On Board Monitor ID (OBDMID), Test ID (TID), Unit and Scaling ID and can be displayed on the GST screen.

The items of the test value and test limit will be displayed with GST screen which items are provided by the ECM. (e.g., if bank 2 is not applied on this vehicle, only the items of bank 1 are displayed)
