MONITOR DESCRIPTION

If the ECM detects the starter control (STA) signal for 20 seconds or more while the vehicle is being driven with an engine speed of 1000 rpm or more at a vehicle speed of 20 km/h (12 mph) or more, it determines that there is a malfunction in the STA circuit, illuminates the MIL and stores this DTC.

Tech Tips

Read freeze frame data using the GTS. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.

  24. CHECK TERMINAL VOLTAGE (POWER SOURCE OF ST RELAY)

    B008MAAC19
    *1 No. 1 Engine Room Relay Block
    *2 ST Relay Holder

    Tech Tips

    The purpose of this step is to check for ST relay holder voltage under abnormal conditions.


    1. Remove the ST relay from the No. 1 engine room relay block.

    2. Turn the ignition switch to ON.

    3. Measure the voltage between ST relay holder 2 and body ground.

      Tech Tips


      • Measure the voltage with the clutch pedal depressed.

      • Make a note of the measured voltage as it will be necessary for the inspecting the change in voltage in the next step. As the next step should be conducted under the same conditions, keep the ignition switch ON and do not install the ST relay.

      • DTCs may be stored during this inspection. Check for DTCs and clear them using the GTS.

      • If any voltage was measured with the ignition switch ON, one of the following malfunctions is suspected:


        • Short to +B in the circuit of a connected ECU or the switch.

        • Short to +B in the wire harness.

  25. INSPECT ENGINE STOP AND START ECU (CHECK FOR SHORT CIRCUIT)

    B008MAAC19
    *1 No. 1 Engine Room Relay Block
    *2 ST Relay Holder

    1. Disconnect the engine stop and start ECU connector.

    2. Measure the voltage between ST relay holder 2 and body ground and compare it to the voltage measured in the previous step.

      Result
      Result Proceed to
      The voltage between ST relay holder 2 and body ground does not change when the connector is disconnected A
      The voltage between ST relay holder 2 and body ground changes when the connector is disconnected B

      Tech Tips


      • Measure the voltage with the clutch pedal depressed and compare it with the voltage measured in the previous step.

      • If the voltage is the same before and after disconnecting the connector, the engine stop and start ECU is normal.

      • DTCs may be stored during this inspection. Check for DTCs and clear them using the GTS.

  26. INSPECT ECM (CHECK FOR SHORT CIRCUIT)

    B008MAAC19
    *1 No. 1 Engine Room Relay Block
    *2 ST Relay Holder

    1. Disconnect the ECM connector.

    2. Measure the voltage between ST relay terminal 2 and body ground and compare it to the voltage measured in the previous step.

      Result
      Result Proceed to
      The voltage between ST relay terminal 2 and body ground does not change when the connector is disconnected A
      The voltage between ST relay terminal 2 and body ground changes when the connector is disconnected B

      Tech Tips


      • Measure the voltage with the clutch pedal depressed and compare it with the voltage measured in the previous step.

      • If the voltage is the same before and after disconnecting the connector, the ECM is normal.

      • DTCs may be stored during this inspection. Check for DTCs and clear them using the GTS.
