P0560
Circuit Description
Circuit RED/WHT is the battery voltage feed for the PCM.
Circuit RED/BLU is the ignition voltage feed for the PCM.
This DTC detects a low voltage or a high voltage. This is a type "D" DTC.
Conditions For Clearing The DTC
System Voltage Low:
- Engine speed is greater than 1,000 rpm.
- System voltage is less than 10 volts at a maximum transmission temperature of 150°C (302°F).
- System voltage is less than 7.3 volts at a minimum transmission temperature of -40°C (-40°F).
- All conditions met for 4 seconds. System Voltage High:
- System voltage is greater than 16 volts for 2 seconds.
Action Taken When The DTC Sets
- Fixed to 4th gear.
- Maximum line pressure.
- Inhibit TCC engagement.
- The PCM will not illuminate the Malfunction Indicator Lamp(MIL).
Conditions For Clearing The DTC
- The DTC can be cleared from the PCM history by using a scan tool.
- The DTC will be cleared from history when the vehicle has achieved 40 warmup cycles without a failure reported.
- The PCM will cancel the DTC default actions when the fault no longer exists and the ignition is cycled "off" long enough to power down the PCM.
Diagnostic Aids
- Charging the battery with a battery charger and jump starting an engine may set DTC(s). If DTC(s) set when an accessory is operated, check for faulty connections or excessive current draw.
- Check for faulty connections at the starter solenoid or fusible link.
- Check for loose/damaged terminals at generator.
- Check belt wear/tension.
