Fuel shut-off


If any of the following criteria are fulfilled, fuel shut-off will take place:


• no power supply (+15 circuit)

• full throttle during starter motor cranking

• engine speed over 6200 rpm.

• engine torque 30 Nm above the maximum permitted at current engine speed

• immobilizer code faulty

• throttle turned by hand when engine running

• serious fault in throttle valve control

• a pedal position sensor fault if engine speed exceeds 2200 rpm

• no power supplied to one of the ignition discharge modules

• engine speed above 1800 rpm with the accelerator pedal released completely and the engine coolant temperature must also be above 20 °C. For manual gearboxes, this applies to 3rd, 4th and 5th gears. For cars with automatic transmission, this applies to 2nd, 3rd and 4th gears. Injection is reactivated at 1400 rpm.


Diagnostics

If TWICE does not send out ”Immobilizer OFF” after the ignition has been switched on or if the Trionic T7, TWICE or MIU control modules are replaced and the immobilization code is not programmed in TWICE, diagnostic trouble code P1460 will be generated and the engine cannot be started.
