Quick answer

For the verified Chrysler Pacifica applicability, P0562 is identified in an FCA service procedure as “System Voltage Low – repair first.” The procedure directs technicians to address P0562 before the high-voltage coolant-heater diagnostic path. Driving and charging status are not yet established by verified evidence.

This page separates verified manufacturer/regulator evidence from supporting material. Unsupported causes, repairs or safety conclusions are not guessed.

1. What does P0562 mean?

For the verified Chrysler Pacifica applicability, P0562 is identified in an FCA service procedure as “System Voltage Low – repair first.” The procedure directs technicians to address P0562 before the high-voltage coolant-heater diagnostic path. Driving and charging status are not yet established by verified evidence.

2. Technical explanation

The supplied official FCA/NHTSA service communication lists P0562, “System Voltage Low,” among faults that must be repaired first when the MIL is on and/or pending DTCs are active. The same communication concerns diagnosis of the high-voltage (ECH) coolant heater. If there is no MIL and no pending fault active, it directs verification of high-voltage coolant-heater status; listed statuses include Locked Until Next Start, Locked Until Next Service, Locked Permanent, and OFF. The supplied evidence does not establish a specific component-level cause of P0562.

3. What system is affected?

The verified procedure relates P0562 to a diagnostic workflow involving the high-voltage (ECH) coolant heater. A broader system assignment is not yet established by verified evidence.

4. How serious is this code?

Unknown. The verified procedure says P0562 is a “repair first” fault, but no severity classification is supplied.

5. Symptoms you may notice

  • A MIL may be on and/or P0562 may be pending, according to the applicable service-procedure scenario.
  • No MIL and no pending faults may also be present in a separate coolant-heater-status verification scenario.
  • Additional vehicle symptoms are not yet established by verified evidence.

6. Possible causes

  • Not yet established by verified evidence. The supplied procedure identifies P0562 as System Voltage Low and instructs that it be repaired first, but does not provide a component-level cause in the supplied evidence.

7. Can I still drive the vehicle?

Not yet established by verified evidence.

8. Can I charge the vehicle?

Not yet established by verified evidence.

9. What you can safely do

  • Arrange diagnosis by a Chrysler-qualified service facility.
  • Provide the stored and pending diagnostic codes to the service facility.
  • Do not attempt high-voltage coolant-heater diagnosis or repair yourself.

10. Step-by-step troubleshooting

  1. A technician should determine whether the MIL is on and/or pending DTCs are active.
  2. Where P0562 is present, the official procedure identifies it as a “repair first” DTC before continuing the referenced coolant-heater diagnostic workflow.
  3. If no MIL is on and no pending faults are active, the procedure calls for verification of high-voltage (ECH) coolant-heater status.
  4. The supplied procedure lists possible heater statuses as Locked Until Next Start, Locked Until Next Service, Locked Permanent, or OFF.

11. When to contact service

Service is recommended because the verified Chrysler procedure classifies P0562 as “repair first.”

12. What the service center may check

  • Check for MIL status and pending DTCs.
  • Address P0562 before the referenced high-voltage coolant-heater diagnostic path.
  • When the no-MIL/no-pending-fault scenario applies, verify high-voltage (ECH) coolant-heater status.
  • Use the FCA procedure applicable to the vehicle for any further diagnosis and repair.

13. Possible repair or resolution

  • Repair details and the final repair resolution are not yet established by the supplied verified evidence.
  • The official procedure requires P0562 to be addressed first in the listed diagnostic scenario.
