Lifetime Members 10,282 Member For: 22y 20d Gender: Male Location: Victoria Posted 14/11/09 11:07 PM Share Posted 14/11/09 11:07 PM It means lost communication with the PCM.Just clear it. If you're car is functions as normal then it doesn't mean much.

Gee Member 131 Member For: 16y 1m 1d Gender: Male Location: Melbourne Posted 15/11/09 08:18 AM Author Share Posted 15/11/09 08:18 AM I did clear it but it keeps coming back. My auto could be acting funny on take off. Sometimes is feels like it has a hi stall but other times the auto works normal. Could the fault code be related.

Posted 16/11/09 08:17 AM Share Posted 16/11/09 08:17 AM (edited) I had the same problem with mine after using a CAPA flash (X3)unit.The Capa unit will not clear that code as its with the auto tran module, not the engine ECU. I have a Scan Tool which checks, erases and lists ALL codes as well veiwing live data.If your in the Eastern Suburbs of Melb. I can erase the code for you no problem.Cheers Peter0418 338 005 Edited 16/11/09 08:18 AM by Peter J Link to comment https://www.fordxr6turbo.com/forum/topic/63577-fault-code-u0100/#findComment-954410 Share on other sites More sharing options...

I`ve heard guys say its the battery on its way out that causes it.Occaisonally I`ll get some of the reported symptoms of this, my ABS and T/C lights come on. I just turn the car off, and hold my tongue in my mouth just right when I turn it back on and its all good.My Battery is new. However the car sits all week, only driven on weekends.
