Cat Lift Trucks (& Caterpillar) 2ET4000:
CAT 2ET4000 Err 0802 inf 1904

I am having trouble figuring out this err code 0802 on this Cat 2ET4000. The unit was being driven down an isle. Went to break, came back, now it doesn't cycle or initialize after starting back up, and just appears this err code 0802. Any codes list, or help with this electric unit would be greatly appreciated. Tested the battery and it is fine.

Code 0802 is CAN NODE SHOWING NO RESPONSE check can circuit pin 3and 8 on the diagnostic port 60 ohms plus or minus ten percent. Check CAN component one by one for power and negative. Disconnect things on the can network and cycle the key this should help you narrow you search Hope it helps.
