Hi Lee

Have you got the schematic of this vehicle with reference to its CAN-bus structure and layout?

Are you aware of the Gateway module / diagnostic interface.?

Have you had any training or self study CBT on CAN-BUS?.

Don't assume The CAN-Bus layout is the same for all makes and models. They are not..


This is a classic example again of "if you do not understand what you are testing ,how can you test it"..
