AUTOMATIC TRANSAXLE SYSTEM, Diagnostic DTC:P061512

DTC Code DTC Name
P061512 Starter Relay Circuit Short to Battery

DESCRIPTION

While the engine is being cranked, battery voltage is applied to terminal STA of the ECM.

If the ECM detects the Starter Control (STA) signal while the vehicle is being driven, it determines that there is a malfunction in the STA circuit. The ECM then illuminates the MIL and stores this DTC.

This monitor runs when the vehicle is driven at 20 km/h (12 mph) or more for 20 seconds.

INSPECTION PROCEDURE

Note

Perform registration and/or initialization when parts related to the automatic transaxle are replaced Click here.

Tech Tips


  • The following troubleshooting procedure is based on the premise that the engine cranks normally. If the engine does not crank, proceed to the problem symptoms table Click here.

  • 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 be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction Click here.

  • After performing repair, clear the DTCs and perform the following procedure to check that DTCs are not output.


    1. Drive the vehicle for 20 seconds or more under the following conditions:


      • Engine speed is 1000 rpm or more.

      • Vehicle speed is 20 km/h (12 mph) or more.

    2. Check for DTCs again Click here.

PROCEDURE


  1. READ VALUE USING GTS (STARTER SW)


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Transmission / Data List / Starter SW.

    5. Check the value displayed on the GTS when the vehicle is driven at 20 km/h (12 mph) or more.

      CAUTION:

      When performing a drive test, obey all speed limits and traffic laws.
