Electrical supply limited, battery is charging

Absmotors · 11-14-2023, 10:04 PM

DME is not reading the battery, I have checked voltage from the battery to the integrated power supply module on the drivers side. No drop in voltage and battery is charging. Dash reads ‘Electrical supply limited’

Need some help with what direction to go from here.

The motor was swapped, this error did not exist before

CD8F01 - LIN message; battery module: missing
D52C79- Signal (vehicle system voltage, 251.2.4) invalid, transmitter DME/DDE
