DTC DETECTION LOGIC

NOTE:


NOTE

:
• Conditions for applying the diagnostic procedure to the stored DTCs: The DTC becomes present during the first 30 seconds after the engine starts.

• In low ambient temperature conditions, diagnostic cannot make difference between a normal long engine start and abnormal long engine start. So, DTC must be take in account only if customer complains about too long or impossible engine start not only in cold conditions but also and especially in warm conditions. If customer complains only in cold conditions, root cause of the problem could elsewhere like low battery level, bad fuel specification (too viscous fuel). This DTC could appear after fuel filter too.

• Special notes:
Starting and engine operation difficult or impossible.
