Code P0601 Volkswagen Description

The nerve center of the fuel injection system is the Engine Control Module (ECM). The ECM constantly supervises the information from various sensors and regulates the systems that start after vehicle performance.

In order to house the program information and the calibrations required for engine, trans-axle diagnostics operation an electrically erasable programmable read-only memory (EEPROM) is used. For detecting errors in the software the ECM uses a specially devised value known as the checksum.
