| Some parameters declared on the supported vehicle list are available depending on the car's equipment and can be reduced. These parameters also aren't available from, for example, the diagnostic computer level. (For example, OPEL VECTRA C car with Z22SE engine has available the "Fuel level" in the car parameter but in the car with Z22YH engine this parameter is not available). || Can't solve the problem.

| Quick Splice / Fast connectors are being used to connect to CAN bus lines. || Sometimes connection places must be soldered because the vehicle CAN bus wires are very thin and CAN adapter wires should be connected directly without using fast connectors.

|| In some vehicles the vehicle's module is active for a long time and they don't enter in the sleeping mode. The CAN adapter can interpret this as the engine is turned on, which may mean that a wrong program number was selected. || Make sure that the correct program number was introduced (look the connection scheme of CAN adapter).
