Diagnostic Trouble Codes: Notes
- If malfunctions do not occur regularly, these are displayed as occurring sporadically ("SP").
- DTC codes appear only on print-out.
- Before replacing components, check the wiring and connections to these components as well as ground connections, according to wiring diagram. See appropriate SYSTEM WIRING DIAGRAMS article.
- The DIAGNOSTIC TROUBLE CODES table lists all malfunctions, with the corresponding 5 digit code numbers that can be recognized by the Data Bus On Board Diagnostic Interface (J533) and printed out by the VAG 1551 scan tool.
- When repair has been carried out, the Diagnostic Trouble Code (DTC) memory must always be erased and checked again with VAG 1551 scan tool. See CHECKING DIAGNOSTIC TROUBLE CODE (DTC) MEMORY and ERASING DIAGNOSTIC TROUBLE CODE (DTC) MEMORY under SELF-DIAGNOSTIC SYSTEM.
NOTE:
If there is a specific complaint and NO malfunctions are recognized after checking DTC memory, carry out "Read measuring value block." See READ MEASURING VALUE BLOCK
