P0560
DTC P0560
Circuit Description
The engine control module (ECM) monitors the ignition 1 voltage to make sure that the voltage stays within the proper range. Damage to components, and incorrect data input can occur when the voltage is out of range. The ECM monitors the system voltage over an extended length of time. If the ECM detects the ignition 1 voltage outside an expected range for the calibrated length of time, DTC P0560 will set.
