My car starts but the lights on the dashboard light up and looses all power and the gear shift does not move unless u override and it still does does have ant peer but the car moves Mechanic's Assistant: Have you checked the fuses? The dashboard bulbs? Went to an electrician and they checked over all the wiring under the dashboar Mechanic's Assistant: What is the make/model/year of your car? Toyota [corolla](/topics-corolla/) 2015 Mechanic's Assistant: Are you fixing your Corolla yourself? What have you tried so far? No, go to an auto electric Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? My fuse to connect the power windows was damaged and I replace is the only thing that was done before this problem arise, pink under the dashboard by the pocket, just in case

Hi carol nice to meet you. For the moment we don’t need the vin number( Chassis Number a 17 digit number) When the [engine](/topics-engine-toyota/) is running you have all the warning lights on like check engine ABS, Trac, Et on? Did your electrician not hook up a diagnostic scan tool and check for malfunction codes? Greg

MRO53REH104529315, YES they ddo scan and it comes up with an error code to the engine with loosing connection, cant remember the codeThey normally change some fuse and it works for about a month or so and happens again this is the 4th time and I am getting fustrated
Automotive Expert
Carol did the code start with a U or a P? Can you remember

Can't remember
Automotive Expert
Ok no problem carol but if you can get to autozone or any parts store that does free diagnostic test and let me know what the code is? Most likely a U code which is a communication code from a wiring issue or a bad control module? Codes will help us. Rgds Greg

Ok, will do
Automotive Expert
Ok Carole stay safe and catch you later on. Greg

Just wanted to mention that this only happens when I park the car and go to restart, no problem otherwise.
Automotive Expert
Ok still let’s check for malfunction codes and see what is happening
