Circuit/System Testing

Verify that DTC P0560 is set as current.
- If the DTC is history, refer to Charging System Test (Solstice) or Charging System Test (SKY) .
Measure the voltage at the battery terminals and compare it with the scan tool ECM Ignition 1 signal parameter. Verify that battery and Ignition 1 signal readings do not differ more than 2.0 volts.
- If greater than the specified value, test the Ignition 1 and ground circuits of the ECM for an open/high resistance.
  - Ignition 1 signal 2.0L X2 terminals 3 -5- 6 and X2 terminal 54.
  - Ignition 1 signal 2.4L X1 terminals 19 - 20 and X2 terminal 13.
  - Ground circuits 2.0L X2 terminals 1- 2 and 4.
  - Ground circuit 2.4L X2 terminal 73.
If the circuits test normal, replace the ECM.
