Right Hand (RH) and Left Hand (LH) Power Sliding Door (PSD) Modules
WARNING: This page is about a different car, the 2004 Mercury Monterey and 2004 Ford Freestar. However, it is still accessible from the selected car via links, so may be relevant.
The RH PSD module and the LH PSD modules are both connected to the ISO 9141 communication network. The modules control opening and closing of the right and left passenger side doors. The ISO communication network will not function if the wire is shorted to ground or battery voltage. Check the network circuit between the PSD module in question and the DLC C251. 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 network, damage to the DLC C251, damage to the PSD module connector, or a problem in the in-line connector. For additional information on this system, refer to BODY SYSTEM - EXTERIOR .
