InternalError 4 (P5V0)
â–¶ How to fix
1: Change HLC unit.
What you'll see
P5V0 out of range.
System reaction
FDC = 127 will: *Stop transmition of HMILEDStatus. *Turn off all outputs. FDC = -128 will: *Allow HLC to continue with normal operation.
Diagnostic depth
Detection
(P5V0_FILTERED[n] < 4500 mV) OR (P5V0_FILTERED[n] > 5500 mV)
Possible cause
Internal HW error.
