F0004 - High Voltage System fault
Error Description
Possible Causes
Possible Solutions
VCU has detected that the HV
system has failed to pass the
precharge stage.
1) ESS fault.
1) Troubleshoot specific error.
The precharge circuit manages the voltage ramp-up
of the HV system upon startup of the vehicle.
Precharge ends when the voltage of the HV
distribution system reaches 95% of the ESS voltage.
The vehicle is then enabled to start. If the HV
distribution system fails to reach the required
threshold within 5 seconds, the VCU will flag
precharge as failed and the vehicle startup will be
aborted.
If precharge has failed, Error F0017 or F0018 is also
expected to appear. If error F0004 appears alone,
the technician should contact Dana for further
investigation.
