- Explanation of the malfunction types (e.g. "open circuit/short circuit to Ground"):
- Before replacing components indicated as malfunctioning, check the wiring and connectors to these components as well as the Ground connections using wiring diagram. This is particularly relevant if malfunctions are output as "occurring sporadically" (SP).
- The malfunctions displayed can be localized using the test table.
- This malfunction "no communication" can also appear with the door control units. This has no influence on the function of the convenience system and is therefore of no consequence. Erase DTC memory
