Faults
Engine management Depending on the seriousness of a recognised fault, the engine can continue to operate with limitations, during which the error lamp lights up continuously or indicates a serious system error by flashing. In this case, the engine should be switched off as soon as safely possible.

Electronic engine control (EMR) The error lamp goes out when all the errors have been eliminated. For some errors, it is necessary to switch off the ignition, wait 30 s and only then switch back on the ignition. The appropriate monitoring functions are switched off when a sensor fails. Only the sensor failure is documented in the error memory.
Depending on the design of the monitoring functions, the electronic engine control can protect the engine in certain problematical situations by monitoring important limit values during operation and checking the correct function of the system components.

The error lamp can release the following signals: ● Function test – Ignition on, error lamp lights up for approx. 2 seconds and then goes out. – Check the error lamp if there is no reaction after switching on the ignition. ● The lamp does not light – After the lamp test an extinguished lamp indicates an error-free and trouble-free operating state within the scope of the control possibility. ● Continuous light Error in system. – Operation continued with restrictions. – The engine must be checked by a DEUTZ partner. – If a lamp lights steadily a monitored measuring variable (e.g. coolant temperature, lubricating oil pressure) has left the permissible value range. Depending on the fault, the engine power may be reduced by the electronic engine control to protect the engine.
– Switch off prompt for the operator. Attention: Failure to do so will lead to loss of guarantee! – The engine has reached switch-off condition. – Engine forced to run with power reduction to cool the engine, with automatic shutdown if necessary. – The switch-off process has been accomplished. – There may be a start lock after engine stop. – The start lock is deactivated by turning off the system with the ignition key for approx. 30s. – optionally the power reduction can be bypassed, the automatic switch-off delayed or a start lock bypassed with the override key on the instrument panel to avoid critical situations. This brief deactivation of the engine protection functions is logged in the control unit. Please contact your DEUTZ-partner in case of malfunctions and sare parts inquiries. Our specially trained personnel will ensure fast, professional repairs using original DEUTZ spare parts in case of damage.
● Flashing Serious error in system.
