Traction voltage (VCB) supply current low – Reduced speed
â–¶ How to fix
Check BMU for DTCs.
What you'll see
None
System reaction
EACS running at reduced speed, which can result in low system pressure.
Diagnostic depth
Detection
The DTC is set to active if: • the e-motor speed is below 13/16 (81%) of the requested speed for at least 5 seconds AND • The BMU is reducing the maximum allowed current to be consumed by the EACS continuously for at least 5 seconds. CAN signals condition: (AUX_VCB_I_MaxCompPos + 0.5A) < AUX_VCB_I_ReqPos). The DTC is set to inactive if: • the e-motor speed is above 15/16 (94%) of the requested speed for at least 5 seconds AND • the EACS is told to run
Possible cause
Low traction supply current in combination with high compressor load
