10 ERRORS
114 Rev. 01/2015
Flash signal Description Potential causes
Flashes six times Misfire rate exceeded on the
supply side
– Defect in the output wiring
– Ignition coil defective
Ignition controller waiting for
standstill
– In Switch Start/Stop mode:
Start/Stop input closed due to
speed exceeding security
speed, ignition release
blocked until engine standstill
10.3.2 Testing Supply Voltage
Risk of damage!
Supply voltage below the defined values will impair the ignition kit function
and can cause the engine to stop running. If the maximum value is
exceeded, the ignition controller may be damaged.
The supply voltage must comply with the following values:
– Minimum 18 V DC
– Maximum 30 V DC
If you suspect a supply voltage interruption, test for this using an oscilloscope. Provided that
you use the digital input for the Switch Start/Stop function, check the Start/Stop control for
leads which may be open, short-circuited or unintentionally grounded.
10.3.3 Testing Pickup Signal
If the pickup transmits a faulty signal during operation, the ignition controller will automatically
stop the ignition. This type of error can be caused by a pickup failure, an open or short circuited
or grounded lead to the pickup, or by a change in the pickup's properties.
Proceed as follows:
– Start the engine with the gas valve closed.
– Using an oscilloscope, test the pickup's signal.
– Ensure that the square wave signal is no less than 2.5 V.
