What is Ficm sync?
FICM SYNC is calculated by the FICM and is the correlation between the camshaft pin and the crankshaft triggers. Once FICM SYNC is achieved, the FICM uses engine speed, MFDES (Mass Fuel Desired), EOT, and ICP to calculate fuel timing, pulse width, and pilot injection usage.
What should my Ficm read?
Voltage supplied from the FICM to the injectors should be at least 45-48 volts with the key on, while cranking the engine and when the engine is running (note that 45 volts is the bare minimum allowed according to Ford).
What is Ficm main power?
A 6.0 FICM or fuel injection control module is what provides power and control to the fuel injectors. The FICM is mounted on supporting brackets above the valve cover on the driver’s side of the engine and was used on the 6.0 Power Stroke engines.
When did Ford stop making 6.0 Diesel?
2010
The 6.0L Power Stroke, was used in Ford Super Duty trucks until the 2007 model year but lasted until 2009 in the Ford Econoline vans (model year 2010) and in the Ford Excursion SUVs until after the 2005 models when Ford discontinued Excursion production.
What should Ficm voltage be while cranking?
Next have someone crank the engine…and see what the FICM voltage is while cranking. Again, it should be >46volts. Go ahead and start the engine and see what the voltage is while idling. If the FICM voltage drops below 46 volts…then it is “bad”…
What does a Ficm relay do?
FICM relays are an oft-neglected afterthought, but provide the critical transfer of amperage from your charging system to the FICM. If your truck has more than 100,000 miles on it, consider a new relay. It may well save you from a killed FICM!
When does the ficmsync PID show Yes?
The FICMSYNC PID will show Yes when the CKPO and CMPO signals are synchronized to the FICM. Symptoms from a loss of SYNC or FICMSYNC or erratic SYNC or FICMSYNC can include: • Crank no start with SYNC No and FICMSYNC No.
Why is my FICM not syncing with PCM?
If there is a wire issue between the PCM and FICM or if the signals are out of time, the FICM SYNC will be NO or may intermittently jump fro YES to NO. • The center connector of the PCM will have to be connected. • While cranking, make sure that the FICM_V and FICM_L powers are above 10.5 volts and the FICM_M power is around 48 volts at all times.
Should the FICM read Yes or no on a Koer?
FICM SYNC should read YES KOER. The FICM SYNC circuit relays info from the PCM to the FICM through 2 wiring circuits, CKPO and CMPO. FICM SYNC problems can be a bad CKP, CMP (electrical or mechanical), PCM, FICM, or harness. 2005 6.0 Would Not Idle… The EGR valve was stuck open with no EGR DTC!
How do I check the FICM sync for engine problems?
• If the vehicle starts and runs rough the FICM SYNC concerns go to the power balance function and click on the enhanced button (has a # symbol on it). If the engine smoothes out, there is a tone wheel concern. • If the vehicle will start only off of an alternative fuel source (silicone spray) and then runs fine, there is likely a cam gear concern.
