Hello, my name is ***** ***** I'm here to help get your problem solved.
Does car even start?
Turn key on-off-on-off-on within 5 seconds and code should display on dash. Let me know, thanks.
It should give you a actual code such as P0440?
Thanks, ***** ***** know.
Have you tried checking codes with a different scantool?
It sounds like your engine computer has probably failed. Only other thing that would cause the no communication problem is a wiring issue which I have not seen any common wiring problems on this vehicle. I'll open question back up to see if someone else has some advice besides bring it to dealer because that would be where we are heading. Someone will reply automatically if they can help. Thanks.
New expert here, sounds like a CAN wire problem between the DLC and the PCM. I can send you a wiring diagram if you would like.
You need a multi meter to check voltage at the Data link connector. do you have a meter?
Double check fuse 33 in the TIPM under hood fuse box.
Check pins 14 and pin 6 on the DLC.
Used chassis body for ground with the meter. Recheck pins 14 and 6 using chassis ground. Pin 16 should have 12 volts to chassis ground.
