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 (12.43 mph) for over 20 seconds.

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Memory Note
P061512 Starter Relay Circuit Short to Battery

Conditions (a), (b) and (c) are met, and a positive (+B) battery voltage of 10.5 V or higher is applied to the ECM for 20 seconds (1 trip detection logic).

(a) Vehicle speed is 20 km/h (12.43 mph) or more.

(b) Engine speed is 1000 rpm or more.

(c) STA signal is on.

  • Park/neutral position switch assembly circuit

  • Starter relay circuit

  • Engine stop and start ECU (w/ stop and start system)

  • ECM

 Comes on DTC stored SAE: P0617

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.


      Powertrain > Transmission > Data List
      Tester Display
      Starter SW

    5. Check the value displayed on the GTS when the vehicle is driven at 20 km/h (12.4 mph) or more.

      CAUTION:

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

      Powertrain > Transmission > Clear DTCs

    5. Turn the engine switch off and wait for at least 30 seconds.

    6. Turn the engine switch on (IG) and turn the GTS on.

    7. Start the engine.

    8. Idle the engine for 5 seconds or more.

    9. Drive the vehicle at 24 km/h (15 mph) or more for 20 seconds or more.

      CAUTION:

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

    10. Enter the following menus: Powertrain / Transmission / Trouble Codes.

    11. Read the DTCs using the GTS.
