DESCRIPTION

The battery supplies electricity to the TCM even when the ignition switch is off. This power allows the TCM to store data such as DTC history, freeze frame data and etc. If the battery voltage falls below a minimum level, the stored data is cleared and the TCM determines that there is a malfunction in the power supply circuit. When the engine is next started, the TCM will illuminate the MIL and set the DTC.

DTC No. DTC Detection Condition Trouble Area
P0560/96

Open in TCM back-up power source circuit.

DTC is detected for 3 sec. or more.

(1-trip detection logic)


  • Open in TCM back-up power source circuit

  • EFI NO. 2 fuse

  • Battery

  • TCM

Tip:

If DTC P0560/96 is set, the TCM does not store other DTCs.

PROCEDURE


  1. Click here

    CHECK FUSE (EFI NO. 2 FUSE)


    1. A003HS4E01

      Remove the EFI NO. 2 fuse from the No. 1 engine room relay block and junction block assembly.

    2. Measure the EFI NO. 2 fuse resistance.

      Standard resistance
      Below 1 Ω

  2. Click here

    CHECK HARNESS AND CONNECTOR (BATT VOLTAGE OF TCM)


    1. Disconnect the TCM connector.

    2. A003AKKE14

      Measure the voltage of the TCM connector.

      Standard voltage
      Tester Connection Specified Condition
      BATT (O3-5) - Body ground 11 to 14 V

  3. Click here

    CHECK DTC OUTPUT


    1. Connect the intelligent tester to the DLC3.

    2. Turn the ignition switch to the ON position.

    3. Turn on the tester.

    4. Clear the DTC (Click here).

    5. Turn the ignition switch off and turn the tester off.

    6. Start the engine and turn on the tester.

    7. Select the item: "Powertrain / ECT / DTC / Current or Pending".

    8. Read the DTCs using the intelligent tester.

    CHECK HARNESS AND CONNECTOR (TCM - BODY GROUND, TCM - EFI NO. 2 FUSE - BATTERY)


    1. A003E3EE42

      Check the harness and the connector between the TCM and body ground.


      1. Disconnect the TCM connector.

      2. Measure the resistance.

        Standard resistance
        Tester Connection Specified Condition
        E1 (O1-1) - Body ground Below 1 Ω
    2. A003CUQE01

      Check the harness and the connector between the EFI NO. 2 fuse and TCM.


      1. Remove the EFI NO. 2 fuse from the No. 1 engine room relay block and junction block assembly.

      2. Disconnect the TCM connector.

      3. Measure the resistance.

        Standard resistance (Check for open)
        Tester Connection Specified Condition
        EFI NO. 2 fuse (2) - BATT (O3-5) Below 1 Ω
        Standard resistance (Check for short)
        Tester Connection Specified Condition
        EFI NO. 2 fuse (2) or BATT (O3-5) - Body ground 10 kΩ or higher
    3. Check the harness and the connector between the EFI NO. 2 fuse and battery.


      1. Remove the EFI NO. 2 fuse from the No. 1 engine room relay block and junction block assembly.

      2. Disconnect the negative battery terminal.

      3. Disconnect the positive battery terminal.

      4. Measure the resistance.

        Standard resistance (Check for open)
        Tester Connection Specified Condition
        Battery positive terminal - EFI NO. 2 fuse (1) Below 1 Ω
        Standard resistance (Check for short)
        Tester Connection Specified Condition
        Battery positive terminal or EFI NO. 2 fuse (1) - Body ground 10 kΩ or higher
