dead battery FORD KUGA 2011 1.G Workshop Manual

• Torque reduction request (stability assistmodule)
• Cruise control request
The PCM sends the following signals via the CAN
databus:
• Fuel pump relay on/off
• Engine speed
• Warning lights on/off (MIL (malfunction indicator lamp), battery warning lamp)
• PAT S
•ECT
• Air conditioning pressure transducer
• Outside air temperature
With the aid of the input and output signals listed
above, the PCM controls / regulates engine
starting, fuel injection and fuel pressure, ignition,
boost pressure, camshaft adjustment, tank purging,
the radiator fan and the refrigerant compressor.
Speed and TDC recording
The CKP uses the PCM sensor to record engine
speed and detect 1st cylinder TDC (top dead
center). An additional sensor wheel for the CKP sensor is
located on the flywheel. This has 60-2 teeth. The
gaps between the teeth are required for detection
of TDC. The CKP sensor works according to the
induction principle and generates a sinusoidal
signal voltage whose level and frequency are
speed-dependent.
From the frequency of the signal the PCM
calculates the engine speed. Each time the engine
rotates, the double gap in the sensor wheel alters
the sinusoidal oscillation that is generated; this
helps the PCM to detect the TDC position of
cylinder 1.
The signal from the CKP sensor is used to
determine
• the crankshaft position,
• the engine speed,
• the ignition timing,
• the injection timing and
• the adjustment angle of the VVT units.
