P0560

DESCRIPTION

The battery supplies electricity to the ECM even when the engine switch is in the off position. 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, these memories are 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 sets 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 ECM

HINT:

If DTC P0560 is set, the ECM does not store other DTCs.

INSPECTION PROCEDURE

HINT:

Read freeze frame data using the intelligent tester. Freeze frame data records the engine conditions when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was running or stopped, 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 (Click here).

1. INSPECT ECM (BATT VOLTAGE)

1. Measure the voltage of the A5 and E4 ECM connectors.

   Standard voltage:

   Tester Connection	Specified Condition
   BATT (A5-4) - E1 (E4-7)	9 to 14 V

NG	REPAIR OR REPLACE HARNESS OR CONNECTOR (EFI FUSE - ECM)

OK
REPLACE ECM
