- Defect in wiring harness between DME and crankshaft
sensor
- Oscillation in reluctor ring (for instance, when starter
engages)
- Reluctor ring contaminated or defective
- Crankshaft sensor defective
Terminal condition: none
Voltage condition:
- Onboard electrical system voltage between 9 V and 16 V

- None
Time condition:
- None
Other conditions:
- Terminal 50 (starter) or,
- engine on, with engine speed > 500 rpm

Condition for fault memory entry
Malfunctions
