  If the engine oil pressure warning lamp illuminates, it could be due to several reasons. First, check if there is an engine oil shortage and replenish the oil if needed. Other potential causes include a clogged engine oil filter (change it), a malfunctioning oil pressure switch (replace it), or loosened/disconnected wiring or connectors (check and fasten them).

  The over crank warning lamp might activate due to several issues. It could be caused by a fuel filter clogging, in which case you should disassemble, clean, and change the filter. Another cause might be a filter clogging in the fuel air-bleeding electromagnetic pump (SDG45S/60S/75S), so change the filter. Also, a malfunctioning fuel cut off solenoid may be the reason, so replace the solenoid. The warning lamp can also indicate that there is no diesel fuel oil, so replenish the fuel. Finally, air mixing in fuel pipings may be the cause, so bleed the air.
