Buzzer sounds after switching on ignition - dynamic oil pressure system


On vehicles with electronic ignition, an impulse is created when the ignition is switched on. This impulse can be read by the dynamic oil pressure control unit as RPM information above 2000 RPM. Since no oil pressure exists, the buzzer is triggered after three seconds.

This condition is normal:

^ No attempt should be made to repair this condition.

^ Inform customers accordingly.
