Hi Knowledgeable Mechanics,

The electrical system in my 2007 Volvo VNL 670 with a D12 engine shuts down every ten minutes or so. The system shuts down both when the engine is running and also when the engine is not running but the key is turning on and the electrical system is on. I installed a new egr cooler and valves but I don’t think it is related. Any ideas would be greatly appreciated.

Codes are:
MID 128 PID 100 FMI 3
MID 128 PID 84 FMI 9
MID 128 PID 171 FMI 9
MID 128 SID 146 FMI 5
MID 128 SID 230 FMI 5
MID 144 PSID 205 FMI 9

ROAD SPEED DATA ERATIC
IDLE VALIDATION SWITCH
ENGINE OIL PRESSURE
AMIENT AIR TEMP COMMUNICATION ERROR
ELECTRICAL FAULT
SAE J1939 DATA LINK DATA ERATIC

Thanks for your help,

Jake

Would start at the batteries and check all your power and grounds first. Sound electrical
