Modern vehicles are equipped with computers that facilitate maintenance and detect potential engine problems. With the engine off, to view these error codes, press the brake pedal and the accelerator fully and hold them down throughout the operation.

Turn the ignition key as if to start the engine, but do not start it; the service display should flash. Every 10 flashes, a digit will be displayed for four digits indicating the error code; in this case, the digit 0170 is displayed.

The error code can be identified by searching online.
