DTC Code DTC Name
P061512 Starter Relay Circuit Short to Battery

DESCRIPTION

  • w/ Entry and Start System:

    • When the engine is being cranked by engine switch operation:

      Current flows from terminal STAR of the certification ECU (smart key ECU assembly) to the park/neutral position switch assembly or clutch start switch assembly and then to terminal STA of the ECM (STA signal). The ECM then performs control to start the engine.

    • When the engine is being cranked by stop and start control:

      Current flows from terminal STA of the engine stop and start ECU to terminal STA of the ECM (STA signal). The ECM then performs control to start the engine.

  • w/o Entry and Start System:

    • When the engine is being cranked by ignition or starter switch assembly operation:

      Current flows from terminal ST2 of the ignition or starter switch assembly to the park/neutral position switch assembly or clutch start switch assembly and then terminal STA of the ECM (STA signal). The ECM then performs control to start the engine.

    • When the engine is being cranked by stop and start control:

      Current flows from terminal STA of the engine stop and start ECU to terminal STA of the ECM (STA signal). The ECM then performs control to start the engine.

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.

  1. Connect the GTS to the DLC3.

  2. Turn the ignition switch to ON and turn the GTS on.

  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

  4. Turn the ignition switch off and wait for at least 30 seconds.

  5. Turn the ignition switch to ON and turn the GTS on [A].

    CAUTION:

    When performing the confirmation driving pattern, obey all speed limits and traffic laws.

  9. Enter the following menus: Powertrain / Engine / Trouble Codes [D].

  10. Read the pending DTCs.

    Tip:

    • If a pending DTC is output, the system is malfunctioning.

    Tip:

    • If the judgment result shows NORMAL, the system is normal.

CAUTION / NOTICE / HINT

Note:

Before replacing the engine stop and start ECU, read the number of starter operations and write it into a new engine stop and start ECU.

Tip:

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.

    *1

    Engine Room Relay Block and Junction Block Assembly

    *2

    ST NO. 1 Relay
    Tip:

    The purpose of this step is to check for ST NO. 1 relay terminal voltage under abnormal conditions.

    1. Remove the ST NO. 1 relay from the engine room relay block and junction block assembly.

    2. Turn the ignition switch to ON.

    3. Measure the voltage between ST NO. 1 relay terminal 2 and body ground.

      Tip:

      • 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 NO. 1 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.
