If warning displays and faults are shown in the PDAS/ABS or other fault memories, they may have been triggered off by the following interference:
- Interference to electronic components or the car's electrical system caused by the ignition current or sparks at gaps in the ignition circuit (incorrectly assembled or loose spark plug caps or damaged ignition leads).
Please refer to Technical Information Group 2 No. 5/89.
- Contact resistance caused by poor earth/ground connections, leading to differences in potential or inadequate screening of speed sensors.
The poor earth/ground connection may not only occur at the affected components but also at other important earthing/grounding points.
