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.

The ECM detects a system voltage below 10 volts for 5 seconds.

DTC P0562 is a C type DTC.

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 V

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

2. Observe the scan tool ECM Ignition  1 Signal parameter. The reading should be between 12.6 and 15.0 V

1. Ignition OFF, disconnect the harness connectors at the 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.

•	Terminal 1 X2 (1.6L)

•	Terminal 2 X2 (1.8L)

•	Terminal 3 X3 (2.0L)

•	Terminal 4X4 (2.4L)

•	Terminal 5X5 (2.8L)

⇒	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 IGN/B+ circuit terminals listed below and ground:

•	Terminal 4 X4 (1.6L)

•	Terminal 5X5 (1.8L)

•	Terminal 6X6 (2.0L)

•	Terminal 7X7 (2.4L)

•	Terminal 8X8 (2.8L)

•

XX

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

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

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
