1. Check if other ECUs in system have raised same DTC, this could indicate a green CAN-bus failure and should perhaps be problem resolved first. If not, continue to next instruction. 2. Disconnect CSS ECU side cable connector and switch off ignition (U15) 3. Measure resistance between CAN Low and High pins on connector, if resistance is about 60 Ohms then problem is likely with ECU, replace it. Otherwise continue to next instruction. 4. Problem is likely with ECU CAN wires, check for wire breakage on CAN low and high as well as cross-coupling.
