How do you remove a Ficm plug?
How do you remove a Ficm plug?
First, push the plugs FURTHER IN to relieve any pressure against the clips. Then, squeeze each plug one at a time one at the base on the long edges and then pull these plugs straight down or wiggle them to and fro to get them out. That’s it.
How to diagnose a 6.0 power stroke FICM?
0 PowerStroke FICM OBDII FAULT CODE DIAGNOSTICS. The below fault codes may help point you in the right direction when diagnosing the 6.0 Power Stroke FICM: P0261 Cylinder 1 Injector Circuit Low. P0264 Cylinder 2 Injector Circuit Low. P0267 Cylinder 3 Injector Circuit Low. P0270 Cylinder 4 Injector Circuit Low. P0273 Cylinder 5 Injector Circuit Low
What are the codes for shorted coils in FICM?
Open coils produce low current which sets the injector circuit low codes (ie. P0261, P0264, … , P0282). Shorted coils (side shorts) or short to grounds produce high current which sets the injector circuit high codes (ie. P0262, P0265, …, P0283).
How does the FICM work with the ignition switch?
It uses engine speed and position signals (*CKPO, *CMPO) to determine when the injectors need to be activated. The ignition switch provides *KEYPWR to the FICM. Once this signal is detected by the FICM, the *MPR output of the FICM will engage the FICM relay. This in turn provides the *FICM PWR and *FICM Logic PWR voltages to the FICM.
When does the FICM cycle through the injector?
The FICM will cycle through the injector outputs when the key is placed in the ON position. This is called pre-cycle and the time of pre-cycle varies with engine temperature. The pre-cycle is done as a self test of the injector circuits. The FICM internally generates 48V used to drive the injector solenoids.
How is FICM calculated in a power stroke engine?
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.
