DESCRIPTION
The battery supplies electricity to the ECM even when the ignition switch is off. This power allows the ECM to store data such as DTC history, freeze frame data and fuel trim values. If the battery voltage falls below a minimum level, the memory is cleared and the ECM determines that there is a malfunction in the power supply circuit. When the engine is next started, the ECM will illuminate the MIL and set the DTC.DTC No.
| DTC Detection Condition
| Trouble Area
|
P0560
| Open in ECM back-up power source circuit (1-trip detection logic)
| - Open in back-up power source circuit
- Battery
- Battery terminals
- EFI MAIN fuse
- ECM

- УКАЗАНИЕ:
- If DTC P0560 is set, the ECM does not store other DTCs or the data stored in the ECM are partly erased.
WIRING DIAGRAM
INSPECTION PROCEDURE
- ПРИМЕЧАНИЕ:
- After replacing the ECM, the new ECM needs registration (See page Нажмите здесь) and initialization (See page Нажмите здесь).
- УКАЗАНИЕ:
- Read freeze frame data using the intelligent tester. 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, and other data from the time the malfunction occurred.
1.CHECK FUSE (EFI MAIN FUSE) |
Remove the EFI MAIN fuse from the engine room relay block.
Measure the resistance according to the value(s) in the table below.
- Standard resistance:
Tester Connection
| Condition
| Specified Condition
|
EFI MAIN fuse
| Always
| Below 1 Ω
|
Reinstall the EFI MAIN fuse.
| REPLACE FUSE (EFI MAIN FUSE) |
|
|
2.CHECK HARNESS AND CONNECTOR (ECM - EFI MAIN FUSE, EFI MAIN FUSE - BATTERY) |
Check the harness and the connector between the EFI MAIN fuse and ECM.
Remove the EFI MAIN fuse from the integration relay.
Disconnect the ECM connector.
Measure the resistance according to the value(s) in the table below.
- Standard resistance (Check for open):
Tester Connection
| Condition
| Specified Condition
|
2 (EFI MAIN fuse) - A50-2 (BATT)
| Always
| Below 1 Ω
|
- Standard resistance (Check for short):
Tester Connection
| Condition
| Specified Condition
|
2 (EFI MAIN fuse) or A50-2 (BATT) - Body ground
| Always
| 10 kΩ or higher
|
Reconnect the ECM connector.
Reinstall the EFI MAIN fuse.
Check the harness and the connector between the EFI MAIN fuse and battery.
Remove the EFI MAIN fuse from the integration relay.
Disconnect the negative battery terminal.
Disconnect the positive battery terminal.
Measure the resistance according to the value(s) in the table below.
- Standard resistance (Check for open):
Tester Connection
| Condition
| Specified Condition
|
Battery positive terminal - 1 (EFI MAIN fuse)
| Always
| Below 1 Ω
|
- Standard resistance (Check for short):
Tester Connection
| Condition
| Specified Condition
|
Battery positive terminal or 1 (EFI MAIN fuse) - Body ground
| Always
| 10 kΩ or higher
|
Reconnect the positive battery terminal.
Reconnect the negative battery terminal.
Reinstall the EFI MAIN fuse.
| REPAIR OR REPLACE HARNESS OR CONNECTOR (ECM - EFI MAIN FUSE, EFI MAIN FUSE - BATTERY) |
|
|
Check the battery voltage.
- Battery voltage:
- 11 to 14 V
Check that the battery terminals are not loose or corroded.
- OK:
- The battery terminals are not loose or corroded.
| REPAIR OR REPLACE BATTERY TERMINAL |
|
|
5.CHECK WHETHER DTC OUTPUT RECURS |
Connect the intelligent tester to the DLC3.
Turn the ignition switch on (IG) and turn the tester on.
Clear the DTCs (See page Нажмите здесь).
Turn the ignition switch off and turn the tester off.
Start the engine and turn the tester on.
Select the following menu items: Powertrain / Engine and ECT/ DTC.
Read the DTCs.
