What’s wrong
On the subject vehicles the control logic which monitors the charging control program fails to divert the electrical power away from the capacitor when a fault is detected within the capacitor circuit. This can cause a short circuit inside the DCDC converter and could cause the engine to stall or overheating of the DCDC converter itself which could cause a fire. The fault is accompanied by the �i-ELOOP� warning light being illuminated on the instrument cluster along with the �i-Stop� warning light flashing The engine may in some circumstances stall and fail to restart. In extreme cases the DCDC converter could overheat and cause a fire
The fix
Reprogram the PCM with the correct control logic. If error code �U3000: 49-DCDC� is stored � the DCDC Converter must also be replaced.
