Manual Trans Sequential - Diagnostics: Pre-Check

  1. Diagnosis System 
    1. Description
      • When troubleshooting OBD II vehicles, the only difference from the usual troubleshooting procedure is that you need to connect an OBD II scan tool (compliant with SAE J1978) or hand-held tester to the vehicle, and read various data output from the vehicle's ECM.
      • OBD II regulations require that the vehicle's onboard computer lights up the MIL on the instrument panel when the computer detects a malfunction in the computer itself or in the drive system components which affect the vehicle emissions. In addition to the MIL lighting up when a malfunction is detected, the applicable DTCs prescribed by SAE J2021 are recorded in the ECM memory (DIAGNOSTIC TROUBLE CODE CHART ).

        If the malfunction does not reoccur for 3 consecutive drive cycles, the MIL turns off but the DTCs remain recorded in the ECM memory.

      • To check the DTCs, connect the hand-held tester or the OBD II scan tool to the DLC3 of the vehicle. The hand-held tester and the OBD II scan tool also enable you to erase the DTCs and check freeze frame data and various forms of engine data (for operation instructions, see the OBD II scan tool's instructions).

      • The diagnosis system operates in the normal mode during normal vehicle use, and also has a check mode for technicians to simulate malfunction symptoms and perform troubleshooting. Most DTCs use 2-trip detection logic (*) to prevent erroneous detections. By switching the ECM to the check mode when troubleshooting, a technician can cause the MIL to light up for a malfunction that is only detected once or momentarily (hand-held tester) (see step  3).
      • 2-trip detection logic:

        When a logic malfunction is first detected, the malfunction is temporarily stored in the ECM memory.

      If the same malfunction is detected again during the second drive cycle, this second detection causes the MIL to light up (2nd trip) However, the ignition switch must be turned OFF between the 1st trip and 2nd trip.

      • Freeze frame data:

        Freeze frame data records the sequential transmission condition when a malfunction (first malfunction only) is detected. When troubleshooting, it is useful for determining whether the vehicle was running or stopped, the engine was warmed up or not, etc. at the time of the malfunction.

    2. Inspect the DLC3.

      The vehicle's ECM uses V.P.W. (Variable Pulse Width) for communication to comply with SAE J1850. The terminal arrangement of the DLC3 complies with SAE J1962 and matches the V.P.W. format.

      DLC3 CONNECTOR TERMINALS VOLTAGE OR RESISTANCE

      Terminal No. Connection/Voltage or Resistance Condition
      4 Chassis Ground - Body/1 Ω or less Always
      5 Signal Ground- Body/1 Ω or less Always
      16 Battery Positive - Body/1 Ω or less Battery Positive - Body/9 - 14 V Always
      NOTE: Connect the cable of the hand-held tester or OBD II scan tool to the DLC3, turn the ignition switch ON and attempt to the scan tool. If the screen displays UNABLE TO CONNECT TO VEHICLE, a problem exists in the vehicle side or the scan tool side.
      • If the communication is normal when the tool is connected to another vehicle, inspect the DLC3 of the original vehicle.
      • If the communication is still impossible when the tool is connected to another vehicle, the problem is probably in the tool itself. Consult the Service Department listed in the tool's instruction manual.
  2. Check Sequential Manual Transmission Warning Light 
    Fig 3: Locating Sequential Manual Transmission Warning Light

    Turn the ignition switch ON and check that the warning light turns off after 5 seconds.

    If the warning light does not light up or does not turns off, check the sequential manual transmission warning light circuit (see SMT Warning Light Circuit ). Also, when the light does not turn off, check DTC as well.

  3. Normal Mode: 

    Inspect Diagnosis 

    1. Check the MIL.
      1. The MIL lights up when the ignition switch is turned ON and the engine does not run.
        Fig 4: Locating Malfunction Indicator Lamp
        G02913973Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
        NOTE: If the MIL does not light up, troubleshoot the combination meter (PROBLEM SYMPTOMS TABLE ).
      2. When the engine starts, the MIL should turn off.
        NOTE: If the lamp remains on, the diagnosis system has detected a malfunction or abnormality in the system.
    2. Check the DTC.
      NOTE: Hand-held tester only:
      When the diagnostic system is switched from the normal mode to the check mode, all DTCs and freeze frame data recorded in normal mode will be erased. Before switching modes, always check the DTCs and freeze frame data, and take notes.
      1. Prepare the hand-held tester or the OBD II scan tool (complying with SAE J1978).
        Fig 5: Connecting Hand-Held Tester To DLC3
        G02913974Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
      2. Connect the hand-held tester or the OBD II scan tool to the DLC3.
      3. Turn the ignition switch ON and turn the hand-held tester or the OBD II scan tool switch ON.
      4. Use the OBD II scan tool or the hand-held tester to check the DTCs and freeze frame data. Take notes. (For operating instructions, see the OBD II scan tool's instructions.)
      5. See DIAGNOSTIC TROUBLE CODE CHART  to confirm the details of the DTCs.

    NOTE: When simulating symptoms with an OBD II scan tool (excluding the hand-held tester) to check the DTCs, use the normal mode. For codes on the DTC chart subject to 2-trip detection logic, turn the ignition switch OFF after the symptoms have been simulated again. When the problem has been simulated twice, the MIL lights up and the DTCs are recorded in the ECM.
  4. Check Mode: 

    Inspect Diagnosis 

    NOTE:

    Hand-held tester:

    1. Compared to normal mode, check mode has a higher level of sensitivity to malfunction.
    2. Furthermore, the same diagnostic items which are detected in normal mode can also be detected in check mode.

    1. Check the DTC.
      1. Initial Condition
        • Battery positive voltage 11 V or more
        • Throttle valve fully closed
        • Transaxle in the N position
        • Air conditioning switched off
      2. Turn the ignition switch OFF.
      3. Prepare the hand-held tester.
      4. Connect the hand-held tester to the DLC3.
        Fig 6: Connecting Hand-Held Tester To DLC3
        G02913975Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
      5. Turn the ignition switch ON and switch the hand-held tester ON.
      6. Switch the hand-held tester from normal mode to check mode. Check that the MIL flashes.
        Fig 7: Measuring Thickness Of Pulse Of MIL
        G02913976Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
      7. Start the engine. Check that the MIL turns off after the engine starts.
      8. Simulate the conditions of the malfunction described by the customer.
        NOTE: Leave the ignition switch ON until you have checked the DTCs, etc.
      9. After simulating the malfunction conditions, use the hand-held tester diagnosis selector to check the DTCs and freeze frame data, etc.
        NOTE: Take care not to turn the ignition switch OFF. Turning the ignition switch OFF switches the diagnosis system from check mode to normal mode, erasing all the DTCs, etc.
      10. After checking the DTC, inspect the applicable circuit.
    2. Clear the DTC.

      The following action will erase the DTCs and freeze frame data.

      Select the CLEAR FREEZE DATA on the DIAGNOSTIC MENU.

      NOTE: If the hand-held tester switches the ECM from normal mode to check mode or vice-versa, or if the ignition switch is turned from ON to ACC or OFF during check mode, the DTCs and freeze frame data will be erased.
