The engine control module (ECM) monitors the battery positive (B+) voltage to ensure that the voltage stays within the proper range. Damage to components, and incorrect data may occur when the voltage is out of range. If the ECM detects low battery voltage, then DTC P0562 will set.

The engine has been running for 3 minutes.

The ECM detects that battery voltage is less than 10 volts for 2 seconds.

DTC P0560 is a type C DTC.

DTC P0560 is a type C DTC.

A low voltage DTC in multiple modules indicates a concern in the charging system.

1. Engine running, accessories OFF, measure and record the battery voltage at the battery terminals. The voltage should be between 12.6 and 15.0 volts.

⇒	If not within the specified range, refer to Charging System Test.

2. Ignition OFF, disconnect the harness connectors at the ECM.
3. Ignition OFF and scan tool disconnected, open and close the driver door, and wait 1 minute. Test for less than 5 ohms between the appropriate ground circuit terminals listed below and ground.

•	Terminal 73 X1 (LNJ)

•	Terminal 1 X2 (LY7)

•	Terminal 2 X2 (LY7)

•	Terminal 4 X2 (LY7)

⇒	If greater than the specified range, test the ground circuit for an open/high resistance.

4. Verify that a test lamp illuminates between the appropriate B+ circuit terminal listed below and ground.

•	Terminal 20 X1 (LNJ)

•	Terminal 56 X2 (LY7)

⇒	If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.

5. Install a 3A jumper wire between the appropriate PWR/TRN relay control circuit terminal listed below and ground.

•	Terminal 59 X1 (LNJ)

•	Terminal 58 X2 (LY7)

6. Ignition ON, verify that a test lamp illuminates between the appropriate ignition circuit terminals listed below and ground.

•	Terminal 18 X1 (LNJ)

•	Terminal 19 X1 (LNJ)

•	Terminal 47 X1 (LNJ)

•	Terminal 5 X2 (LY7)

•	Terminal 41 X2 (LY7)

•	Terminal 54 X2 (LY7)

⇒	If the test lamp does not illuminate, test the ignition circuit for a short to ground or an open/high resistance.

7. If all circuits test normal, replace the ECM.

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
