Circuit/System Description
The engine control module (ECM) monitors the system 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.
Conditions for Running the DTC
The ignition is ON.
Conditions for Setting the DTC
The ECM detects a system voltage out of range for 2 seconds.
Action Taken When the DTC Sets
DTC P0560 is a C type DTC.
Conditions for Clearing the DTC
DTC P0560 is a C type DTC.
Diagnostic Aids
A low voltage DTC in multiple modules indicates a concern in the
charging system.

Circuit/System Verification
Engine running, accessories OFF, measure and record the battery
voltage at the battery terminals. The voltage should be between
12.6 and 15.0 V.
If not within the specified range, refer to
Charging System Test .
Circuit/System Testing
| 1. |
Ignition OFF, disconnect the
harness connectors at the K20 ECM. |
| 2. |
Ignition OFF and scan tool
disconnected, open and close the driver door, and wait 1 minute.
Test for less than 5 Ω between the ground circuit terminals
listed below and ground. |

| ⇒ |
If greater than the specified range, test the
ground circuit for an open/high resistance. |
| 3. |
Ignition ON, verify that a
test lamp illuminates between the B+ circuit terminals listed below
and ground. |

| ⇒ |
If the test lamp does not illuminate, test the B+
circuit for a short to ground or an open/high resistance. |
| 4. |
If all circuits test normal,
replace the K20 ECM. |
