Welcome to DF
Does the screen come on at all when you plug into the DLC? If it doesn't ck the fuses, I think its fuse 23.

 

Im not quit sure. my mother went to get it inspected and the guy she spoke to said it wouldnt read ne thing. i kno we went to auto zone and tried to hook it up to a pocket scanner and it just said searching or something like that and didnt come up with ne thing. i checked all the fuses under the hood and they seemed to be alright besides the plastic on relay 4608650 was broken but seemed to be alright inside. the whole outer plastic shell came off when i went to pull it out. i didnt notice a 23fuse? i looked under the dashboard under the steering wheel and did notice it was missing relay 1-2-5-6-7-8-11-12-drl3. i hope maybe something there might help out.

Bump.

 

Bump.

 

Fuses good? Disconnect the negative battery cable a few minutes. Still dead? Probably a bad powertrain control module better known as a PCM or wiring.

 

What type of scanner are you using?

 

im not sure what scanner the guy used at the inspection place. i wasnt there when my mom tried to get it inspected. im guessing the standard machine they use to to hook up to the obd2 at an inspection place? we even went to auto zone and used a pocket scanner to see what would happen and nothing. it just said searching or scanning or something like that, and then nothing popped up. maybe it the obd2 system itself is junk?

 

You may need to have the dealer to ck codes with a DRB3 scanner and if the screen reads blank, they would be able to ck the problem.

 

ok. thanks for all your help. was trying to avoid going to the dealer but seems like that is my the only option. will lyk when i have the solution.
