Troubleshooting table x = Possible o = Probable 17 1. EDC self-diagnosis or flash code output 2. Starter turns over engine only slowly or not at all 3. Starter turns, engine does not start, engine does not start / difficult to start when cold 4. Engine stalls (dies) during operation, no longer starts (starter turns), engine does not start/starts with difficulty when hot 5. Sudden, temporary engine shutdown, engine does not reach full revs 6. Engine only runs at idle speed, no throttle response 7. Engine only runs at increased idle speed, no throttle response 8. Rated engine speed distinctly reduced (even under no load) 9. Reduced output in all ranges 10.
Irregular engine operation, traction loss 11. Unstable idle speed, engine hunting, misfiring, knocking in engine 12. Engine judder 13. Unusual combustion noise 14. Excessive smoke emission: White smoke/blue smoke 15. Excessive smoke emission: Black smoke 16. Engine temperature too high (coolant loss) 17. Fuel consumption too high 18. Lubricating oil pressure too low 19. Lubricating oil pressure too high 20. Lubricating oil consumption too high 21. Engine too “loud” / mechanical noise 22.
