Catalytic converter
The effectiveness of the catalytic converter can only be tested with an
emissions tester.
Before replacing a catalytic converter suspected to be defective, take a
test ride and use the KTM diagnostics tool to check the injection
system for proper functioning.
Idle speed control motor (output)
The idle speed control motor
1 can be tested and controlled with the
KTM diagnostics tool.
In case of an error, perform the following tests:
– Check the wiring and connectors for continuity from the idle speed
control motor to the control unit (control unit disconnected).
– Check the coil resistance of the idle speed control motor (between
the grey and purple or white and green cables). At 20ºC each of the
two coils should have a resistance of approx. 8 Ω.
Control motor for the 2nd throttle valve (output)
The control motor
2 can be tested and controlled with the KTM
diagnostics tool.
In case of an error, perform the following tests:
– Check the wiring and connectors for continuity from the idle speed
control motor to the control unit (control unit disconnected).
– Check the coil resistance of the control motor (between the blue and
red or yellow and grey cables). At 20ºC each of the two coils should
have a resistance of approx. 6.5 Ω
