U0232 - Lost Communication With Side Obstacle Detection Control Module - Left

This isnt a post as much about the diag as about the affects of network faults on certain functions of the vehicle. This car came in with complaint of fuel guage stuck on E and Turn Signal indicator erratic on the IPC. Also Service Side Detection System displayed in the DIC on start up. When I got the car the fuel guage was fine. But the Service message and the Turn Signal indicator fault were still current. I didnt plan on posting this diag. The videos are actually for my 15 year old brother who is working in a repair shop this summer and Im just showing him the diag side of this industry. So the videos may seem a little elementary but just wanted to show the effects of a network fault. I thought it was cool how that glitch was affecting the turn signal. The Right Side Object Detection Module had the U0232 lost comm with Left Side Object Detection Module. I also could not communicate with Left Side which is why I unplugged it in the video. And there is a recall on the 2 Side Object Modules for water intrusion. They were backordered for 2 months. We just got them last week so the back order is over now. Enjoy!!

Your report supports that we should always look in service information before starting a diagnostic. It can really…
