Engine load
Crankshaft position sensor
Camshaft Hall sensor
Coolant temperature sensor
Intake air temperature sensor/charge air.
Coil ignition: The ME control unit interrupts at the point of ignition timing at the ground end the ignition
coil primary circuit of the ignition coil.
ECI ignition system (engine 137): The ME control unit actuates the output stages in the ECI ignition
modules.
The ignition angle can only be checked with the HHT/STAR DIAGNOSIS.
2.Ignition angle adaptation
2.1 Catalytic converter heating-up (warming-up)
The ignition angle is continuously retarded for about 20 seconds in order to more rapidly warm up the catalytic
converter to its operating temperature if:
coolant temperature at start > 15 °C and < 40 °C
Selector lever position P or N
At the same time idle speed is increased by the idle speed control.
2.2 Idle speed
To assist the idle speed control, the ignition angle can be retarded by as much as 36° crank angle or advanced by
as much as 20° crank angle.
Altering the ignition angle provides a more rapid control than altering the position of the throttle valve (idle
speed control).
2.3 Deceleration fuel shutoff
The ignition angle is briefly retarded when combustion is resumed (fuel injectors actuated) in order to prevent a
sudden increase in torque.
2.4 Intake air temperature/coolant temperature
The ignition angle is retarded under load, as a function of the intake air temperature and coolant temperature, in
order to prevent an
y knocking tendency at high intake air and coolant temperatures. The ignition angle is

Page 2172 of 4133
"Retarded" if:
Intake air temperature > 35 °C
Coolant temperature > 105 °C
In supercharged engines the charge air temperature is used as information for the ignition timing adjustment in
place of the intake air temperature.
The values of the retardation of the ignition angle of intake air temperature and coolant temperature are added
together.
2.5 Transmission overload protection
In order to protect the shift elements of the automatic transmission during power shifts (1-2-1, 2-3-2) from
excessive thermal stresses, the ignition angle is briefly retarded during the gearshift and the engine torque
reduced as a result. The ME-SFI control units are supplied with a signal for this purpose from the ETC control
unit (N15/3) over the CAN databus.
2.6 ESP/ASR control mode
In order to reduce the engine torque as rapidly as possible in the ESP/ ASR control mode, the ignition angle is
retarded by the throttle valve actuator (opening angle reduced) prior to the control mode being activated. The
information from the ESP/ASR control unit is supplied over the CAN databus to the ME-SFI control unit.
2.7 Anti-knock control (AKC)
If uncontrolled combustion (knocking) occurs at one or several cylinders, the ignition angle at the relevant
cylinder or cylinders is "Retarded".
2.8 Smooth engine running analysis
To restrain the three way catalytic converter from thermal overload through combustion misfiring and in order
to keep the exhaust emission values, the smooth operation of the engine is continuously monitored.
If combustion misfiring is identified at one or several cylinders, the corresponding fuel injection valves are no
longer actuated after a certain number of misfires.
Engine 104, 111, 112, 113, 119, 120: Smooth operation evaluation is performed through the signals of the
crankshaft position sensor.
Engine 137: Identification of combustion misfiring by means of ionic current signal, see ECI ignition system
function.
