What is Ficm relay?

FICM relays are an oft-neglected afterthought, but provide the critical transfer of amperage from your charging system to the FICM. This relay is located under the hood on the drivers side fender well in the fuse panel next to the firewall.

What makes a Ficm go bad?

Any voltage reading below 45 volts indicates a bad FICM and will need to be replaced. If you receive a 0 voltage reading while cranking you may have a bad FICM fuse and or relay. If voltage drops below 45 volts the FICM will require replacement.

What does FICM do on Ford 6.0L Powerstroke engine?

On Ford 6.0L Powerstroke engines, the purpose of the Fuel Injection Control Module (FICM) is to supply 48 volts to the two solenoids that control pressurized oil flow to the fuel injector. The FICM uses a series of internal capacitors to turn the vehicle voltage (12-14.5 volts) into the 48-volt supply.

Why does my 2006 F250 lose FICM sync?

I am working on a 2006 f250 that has a complaint of bucking and jerking while driving. I have verified the concern and the truck is losing ficm sync while at highway speeds. It is intermittent but I can replicate it everytime I drive it. There are no codes except a fuel delivery error code in the tcm.

What are the symptoms of a 6.0 power stroke FICM?

The 6.0 Power Stroke FICM is often mis-diagnosed and needlessly replaced. Calibration concerns, powertrain component faults and FICM malfunctions may produce similar drivability concerns. NOTE: The most common symptoms of a failed FICM are: NO START or CONSTANT MISFIRE AT ALL ENGINE TEMPERATURES.

Why does my Ford 6.0L start hard?

Truck owners will often tolerate the condition, but if it’s not addressed it can eventually lead to injector damage. In many cases, it may result in a crank no start condition. So why does a cold start and thick oil cause a 6.0 Powerstroke to start hard? The FICM supplies voltage to two solenoids (magnets) on the top of the fuel injector.

What is the FICM code on a 6.0L Powerstroke?

The FICM is a common “pattern failure” part on the 6.0L Powerstroke Diesel. Common concerns when failure occurs are no starts, hard starts, and rough engine operation when cold. These symptoms are often accompanied by codes P0611, P1378 and possibly all (8) injector low circuit codes (P0261, P0264, P0267, P0270, P0273, P0276, P0279 & P0282).

What are the symptoms of Ford 6.0 power stroke FICM?

Calibration concerns, powertrain component faults and FICM malfunctions may produce similar drivability concerns. NOTE: The most common symptoms of a failed FICM are: NO START or CONSTANT MISFIRE AT ALL ENGINE TEMPERATURES. Symptoms other than these are not likely to be caused by the Ford 6.0 FICM module.

Is the Ford 6.0 FICM a better than new product?

Our Ford 6.0 FICMs are professionally remanufactured – they completely disassembled, and upgraded components are installed – giving you a “better than new” product in terms of reliability. Each 6.0 Powerstroke FICM is thoroughly tested on a proprietary vehicle simulator to ensure that it will function correctly before shipment.
