What does this fault code mean?
The instrument cluster (DIM) receives signals from the pedestrian protection module (PPM) with a lower quality than it can accept. The driver normally notices nothing, but the code shows that the signal from the pedestrian protection cannot be relied on. The fault usually lies in the pedestrian protection module or the central electronic module, and
Possible causes
- The fault probably lies in the pedestrian protection module (PPM)
- The fault may lie in the central electronic module (CEM)
What you can do
- 1Read the fault codes with a diagnostic tool, clear them and road test the car to see whether the code returns
- 2Check that the fuses are intact. Their location is in the owner's manual or the fuse list
- 3If possible, test a few functions in the car with the buttons and controls to see whether any other fault shows in the instrument cluster
- 4If the code remains after clearing, have a workshop investigate the pedestrian protection module and the central electronic module
- 5Do not replace the instrument cluster until a workshop has shown the fault lies there, as the signal usually comes from another module
Symptoms you may notice1
- No noticeable symptoms for the driver
