2010 Cadillac Truck SRX AWD V6-2.8L Turbo Page 1417
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 that the battery voltage is less than 2.54 V for 5 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 Testing
1. Engine running, accessories OFF, measure and record the battery voltage at the C1 battery terminals. The voltage should be between 12.6 and
15.0 V.
瀚慖f not within the specified range, refer to Charging System Test (See: Starting and Charging/Testing and Inspection/Component Tests
and General Diagnostics/Charging System Test).
2. S39 Ignition Switch OFF, disconnect the harness connectors at the K20 ECM.
3. S39 Ignition OFF and scan tool disconnected, open and close the driver door, and wait 1 minute. Test for less than 5 Ohms between the
