Hello Folks,
This is in a 1995 MCI tour bus with DDEC3 with only 150k on a rebuild. Diamond seal is leaking already even though the update was done.
Bus runs great, no smoke, idles fine.
CEL comes on when the jakes and only when the jakes activate. This is in either high or low jake switch setting. The flash code 41 I am familiar with. TRS and SRS actual sensors check out, and harness all check out. Anything else I can try before I have to track down a test ecm. That seems the be the sequence in the book. Any ideas? Or has anyone seen this symptom on one like it?
Thanks!
