DTC Fault Trigger Conditions
DTC Description Fault Trigger Condition SOBDMC P0560:00 System Voltage: No Sub Type Information This DTC sets when the internal processor voltages are greater than a calibrated range. SOBDMC P0562:00 System Voltage Low: No Sub Type Information This DTC sets when the internal processor voltages are less than a calibrated range. Possible Sources
- Wiring, terminals or connectors
- Low 12V battery voltage
- BV1 CHECK THE INVERTER SYSTEM CONTROLLER (ISC) CIRCUIT FOR VOLTAGE
- Ignition OFF.
- Disconnect Inverter System Controller (ISC) C1458A.
- Ignition ON.
Is the voltage greater than 11.5 V?
Yes GO to BV2 No DIAGNOSE the low voltage symptom. REFER to: Charging System - 2.7L EcoBoost (238kW/324PS)/3.5L EcoBoost (BM) . Using a diagnostic scan tool, clear the Inverter System Controller (ISC) DTCs. - BV2 CHECK THE INVERTER SYSTEM CONTROLLER (ISC) CIRCUIT FOR VOLTAGE
Is the voltage less than 16V?
Yes GO to BV3 No DIAGNOSE the high voltage symptom. REFER to: Charging System - 2.7L EcoBoost (238kW/324PS)/3.5L EcoBoost (BM) . Using a diagnostic scan tool, clear the Inverter System Controller (ISC) DTCs. - BV3 CHECK FOR INVERTER SYSTEM CONTROLLER (ISC) DIAGNOSTIC TROUBLE CODES (DTCS)
- Using a diagnostic scan tool, clear the Inverter System Controller (ISC) DTCs.
- Allow the Inverter System Controller (ISC) to complete a normal power down sequence.
- Using a diagnostic scan tool, perform the Inverter System Controller (ISC) self-test.
Is DTC P0560 or P0562 present in the Inverter System Controller (ISC)?
Yes GO to BV4 No Test is complete, the system is operating correctly at this time. - BV4 CHECK THE PSR VOLTAGE PARAMETER IDENTIFICATIONS (PIDS)
- Access the SOBDMC and monitor the ECU_VPWR (V) PID
- Access the SOBDMC and monitor the ECU_VPWR_HR (V) PID
Are the PID voltages within 3 volts of each other?
Yes While monitoring the PIDs, inspect the harness for an intermittent circuit issue while wiggling the harness at the Inverter System Controller (ISC). No REPAIR the affected circuit.
