    I have a 1999 Kenworth T800 with a Cat C12 engine. Check engine light is on. All fluid levels are good, new oil change and new filters, runs good, oil pressure is good.
    I turn the key on then hit the resume switch the code flashes once then pause then flash two times pause then once pause then flashes four times. So 1-2 then 1-4? Anyone know what that is?
