Service: Electrical > Off line – all modules
Problem
Off line – for instrument cluster, hitch, trans, engine, PTO, aux, arm
Solution
Fault on the Can Data Bus circuit where there are two terminators for data transfer.
CDB is a four-wire harness interfaced to each controller. The signal (high and low) transfers the information between the electronic modules.
If the terminators are measured and there are no 2.5V values on the signal then they have to be replaced. It is possible that only one is defective and then the data transfer is blocked.
You should measures the 12V supply on the red wire.
