| Fitting location of the EPC warning lamp -arrow-. |
| After switching on the ignition the engine control unit checks all the components that are relevant to the operation of the EPC. |
| During the inspection of these components, the engine control unit switches on the EPC lamp for approximately 3 seconds. If a fault is found during the inspection, the lamp lights up permanently. |
| If during engine operation faults are detected in the electronic throttle system, the engine control unit switches on the EPC lamp. (These faults are stored in the fault memory.) In the event of a line interruption or a fault in the Electronic throttle system the engine switches to emergency operation. In emergency operation the engine runs at increased speed so that the customer is able to reach the next workshop. However, the accelerator pedal position senders no longer operate. |
