Start-Stop Dead / Hybrid Fault Lamp

Diagnosis & fix steps

LOGIC: 48V Mild-Hybrid DC/DC Converter System Voltage Low. ACTION: Inspect low-voltage ground return stud on the 48V-to-12V bidirectional converter. Check 48V lithium-ion battery pack state of health (SOH) and load test main 12V AGM auxiliary battery.

Red Seal field insights

Dual-Voltage Loop: If the 12V lead-acid battery develops high internal resistance, the 48V DC/DC converter over-saturates trying to support cabin electrical loads, dropping the bus.
