Power Liftgate Module

The power liftgate module is connected to the ISO 9141 communication network. The module controls opening and closing of the vehicle liftgate. The ISO 9141 communication network does not function if the wire is shorted to ground or battery voltage. Check the network circuit between the power liftgate module and the DLC C251. The total resistance value must not be more than 5 ohms. If the resistance is more than 5 ohms, there is an open circuit in the ISO 9141 communication network, damage to the DLC C251, damage to the power liftgate module C4174a, or a problem in the in-line connector.
