Co oznacza ten kod błędu?
The driver and passenger door modules (DDM/PDM) control the window lift in each front door via a relay. The module has detected that the relay for the window motor down direction is active when it should not be, which may be because the relay has stuck.
Możliwe przyczyny
- Someone has run the window with diagnostic equipment
- The relay has stuck in the active position
Co możesz zrobić
- 1If the window lifts have recently been operated with diagnostic equipment at a workshop, that may be the cause; clear the code and check whether it comes back
- 2Check that the front door window does not drop by itself when no switch is pressed
- 3Check that the fuses for the window lifts are intact in the fuse box
- 4Check that the connectors at the door module and the window lift motor are secure and free from moisture and oxidation
- 5If you have diagnostic equipment, read the relay status in live data when no switch is in use and check whether it shows the active state
- 6If the fault remains: have a workshop check whether new software needs to be downloaded to the door module and whether it needs replacing
Objawy, które możesz zauważyć1
- The electric window does not work, works with reduced function or works incorrectly
Na co może wpływać usterka1
- The control module activates the relay for the window lift up instead
