MANUAL TRANSAXLE SYSTEM DIAGNOSIS SYSTEM


  1. EURO-OBD (EUROPEAN SPEC)


    1. When troubleshooting Europe On-Board Diagnostic (Euro-OBD) vehicles, an OBD scan tool (complying with ISO 15765-4) must be connected to the vehicle. Various data output from the vehicle's ECM can then be read.

    2. B008MAD

      Euro-OBD regulations require that the vehicle's on-board computer illuminate the Malfunction Indicator Lamp (MIL) on the instrument panel when the computer detects a malfunction in any of the following:


      • The emission control system/components

      • The powertrain control components (which affect vehicle emissions)

      • The computer

      In addition, the applicable Diagnostic Trouble Codes (DTCs) prescribed by ISO 15765-4 are stored in the ECM memory. If the malfunction does not reoccur in 3 consecutive trips, the MIL turns off automatically but the DTCs remain stored in the ECM memory.

    3. To check for DTCs, connect the GTS or OBD scan tool to the Data Link Connector 3 (DLC3) of the vehicle.

      The scan tool displays DTCs, the freeze frame data and a variety of engine data.

      The DTCs and freeze frame data can be cleared using the scan tool.

  2. M-OBD (EXCEPT EUROPEAN SPEC.)


    1. When troubleshooting Multiplex On-Board Diagnostic (M-OBD) vehicles, the vehicle must be connected to the GTS. Various data output from the ECM can then be read.

    2. A001YBE

      OBD regulations require that the vehicle's onboard computer illuminate the MIL on the instrument panel when the computer detects a malfunction in any of the following:


      • The emission control system/components

      • The power train control components (which affect vehicle emissions)

      • The computer

        In addition, the applicable Diagnostic Trouble Codes (DTCs) prescribed by ISO 15765-4 are recorded in the ECM memory.

        If the malfunction does not recur in 3 consecutive trips, the MIL goes off automatically but the DTCs remain recorded in the ECM memory.

  3. FUNCTION OF WARNING INDICATOR AND MESSAGE


    1. If the iMT system is not functioning properly, the driver is warned by the iMT warning light or a warning message on the multi-information display in the combination meter assembly.

      DTC Master Warning Light iMT Indicator Warning Message Detail
      DTCs are output Comes on Does not come on Displayed iMT system malfunction
      DTCs are not output Does not come on

      iMT indicator (Green):

      Comes on

      		 Not displayed iMT system standby condition

  4. FREEZE FRAME DATA

    The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was moving or stationary, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data stored at the time of a malfunction.

  5. CHECK DATA LINK CONNECTOR 3 (DLC3)


    1. Check the DLC3.

  6. CHECK BATTERY VOLTAGE

    If the voltage is below 11 V, replace or recharge the battery before proceeding to the next step.
