P0560

DTC P0560 System Voltage

MONITOR DESCRIPTION

DTC Detecting Condition:

Monitor Strategy:

Typical Enabling Conditions:

Typical Malfunction Thresholds:

The battery supplies electricity to the ECM even when the ignition switch is OFF. This electricity allows the ECM to store data such as DTC history, freeze frame data, fuel time values, and other data.

If the battery voltage falls below a minimum level, the ECM will conclude that there is a fault in the power supply circuit. The engine starts in the next time, the ECM will turn on the MIL and a DTC will be set.

HINT: If DTC P0560 present, the ECM will not store another DTC.

INSPECTION PROCEDURE

Step 1:

Step 2 - 3:

HINT: Read freeze frame data using the hand-held tester or the OBD II scan tool. Freeze frame data records the engine conditions when a malfunction is 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, as well as other data from the time when a malfunction occurred.

CHECK FOR INTERMITTENT PROBLEMS

Hand-held tester only:
Inspect the vehicle's ECM using check mode. Intermittent problems are easier to detect when the ECM is in check mode with hand-held tester. In check mode, the ECM uses 1 trip detection logic, which has a higher sensitivity to malfunctions than normal mode (default), which uses 2 trip detection logic.

a. Clear the DTCs (see step 2).
b. Set the check mode (see step 3).
c. Perform a simulation test.
d. Check the connector and terminal.
e. Wiggle the harness and connector.
