3.0 2005 P0730 P0702 Restricted Performance

[Kris88]

Hi all. I am getting Restricted Performance with check engine light, orange and red light on the dash and Cruise not available. SDD is reading P0730 and P0702 from TCM and P0702 from ECM with P1000. Sometimes they just go off randomly but coming back. I have changed ABS sensor last week, cause that was another issue with ABS DSC lights on dash, but now they gone, just that Performance left. Has anyone ever had those errors? Where should I start? Gearbox is running fine. Car been sat for a while due to pandemic, battery has been changed to brand new one, fully charged. Is it possible that I have to re-calibrate something in gearbox settings etc? How to do it, if so? Thanks in advance!!

hi

702 is a battery fault, I'd check all the battery connection and connections to the body earth, also check the mega fuse connection and fusebox, make sure nothing loose

730 is a gearbox ratio fault, but could be related to the battery fault

cheers

Hi Joe. Thank you for your reply! 

What is mega fuse?

 I hope you're right, cause I'm having sleepless nights already thinking about a need of new gearbox..
