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. Possible Sources
- Wiring, terminals or connectors
- 12V Battery
- BR1 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). GO to BR2 No With the aid of the wiring diagram, REPAIR the affected circuit. - BR2 CHECK THE INVERTER SYSTEM CONTROLLER (ISC) VBATT CIRCUIT VOLTAGE
- Ignition OFF.
- Disconnect Inverter System Controller (ISC) C199A.
- Ignition ON.
- Measure:
Positive Lead Measurement / Action Negative Lead C199A-34 Ground
Is the voltage within 2 volts of battery voltage?
Yes Test is complete, no faults were found. CLEAR the Inverter System Controller (ISC) DTCs. No DIAGNOSE the high battery voltage symptom
