spn 1569 relates engine protection torque derate -condition exists.
critical fault codes related to engine operation are active
code 1 means urgent attention
A sort of limp mode setting that requires immediate attention by a cummins service center to prevent further damage to the engine
go google and type in--- cummins engines fault codes (or cummins engine fault code 1569) and there are pages of pdf downloads that list all the codes and what they stand for
check the codes for faults
Some engines ( international for example ) idled on 4 cylinders and the rest cut in on power or rpm's requirement
If your engine has the same set up the fault will be in that control unit
faulty aftertreatment outlet, ....... knock sensor, and check coolant temp sensor,if it is faulty it will cause a rich condition that can throw misleading codes. knock sensors often fail and throw code when no other fault is present. good luck and happy motoreing!
Spn codes are not very good indicators of what's going on. This is a general protocol that all manufactures use and I don't find it reliable. If there is an engine light on with a wrench in it. Get to the dealer. If there is no wrench it's not as urgent.
