WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
The Side Obstacle Detection Control Module - Right (SOD-R) and Side Obstacle Detection Control Module - Left (SOD-L) receive network messages from the Instrument Panel Cluster (IPC) via the Medium Speed Controller Area Network (MS-CAN). The following information is included in the messages:
- Transmission gear selected
- Vehicle speed
As more than one module receives these messages, all modules receiving a particular message should exhibit a symptom if the message is missing.
- DTC U0155:00 (Lost Communication With Instrument Panel Cluster (IPC) Control Module: No Sub Type Information) - set by the SOD-R or the SOD-L when network messages are missing from the IPC for greater than 2 seconds with the ignition in RUN.
This pinpoint test is intended to diagnose the following:
- Communication network concern
- Blind Spot Information System (BLIS™)/Cross Traffic Alert (CTA) system concern
- IPC
