Default Why OBD not respond?

Hi.

My PT is trouble with transmission and I notice P0700 code on dash.

So, I go to dealer and ask for sub code for P0700.

Dealer connect OBD3 and Said "It not working. You must change your TIPM."

Is really true? I can't understand. dealer said also "Price is about $700 over.."

And another question.. My center fascia goes hot when I use heated seat or

turn on another electrical device.

Thanks for reading this.

Have you tried resetting with an OBDII Scan Tool to see if it comes back? Sometimes if your battery voltage goes low enough it will give you random codes.

More information is needed if the P0700 comes back.
What year is your PT Cruiser?
How many miles?
When was the last time the transmission oil filter and oil changed?

Not sure if I am right or not, but many times when I've seen OBD2 scanners unable to communicate with the car, the car had a bad cigarette lighter fuse and upon changing the fuse it worked fine. Not sure if this would be the same for a PT cruiser, but it's a quick check.

Have you tried resetting with an OBDII Scan Tool to see if it comes back? Sometimes if your battery voltage goes low enough it will give you random codes. - Battery voltage not low i think. everything normal except code and OBD connect..

More information is needed if the P0700 comes back.
- P0700 code comes three times and PRND indicator blink sometime.
When I stop my engine and start again, symptom goes away for a while.
What year is your PT Cruiser? - 2006
How many miles? - about 75000 miles.
When was the last time the transmission oil filter and oil changed?
- two month ago.

Thanks very much for your comment.

- When I check TIPM, dealer check every fuse and said every fuse good.

But I will check cigarette fuse again. Thank you for comment.

Is the MIL currently on?

Try this reset procedure, it's a little bit different than just disconnecting the battery:

My PT is currently experiencing some of the same symptoms as yours, and I have the same model as you. My UG is showing trouble codes of P0700 and P0562, and occasionally the airbag light may come on for a few seconds, but they have not yet tripped the MIL.

It had been shifting a little rough lately and I had the transmission fluid exchanged and the filter replaced. It does appear to shift much smoother now.

I've cleaned the battery terminals and reseated the PCM connectors, so I guess I'm in a holding pattern until an actual failure of a component or the MIL actually trips.
Thanks for comment.

I.don't understand the word MIL and in image you tag two batt cable touch together????

I wann know about that.

I DO NOT RECOMMEND.........

The battery disconnect is NOT the way to do any ECU/PCM/TCM,Monitors, etc., in the case of any diagnostic issues that you are trying resolve . It only will prolong and in many cases complicate the processes to find the issues.


If you or anyone is having P0700 codes or any issues out of the normal transmission operations I suggest to go to a Transmission service shop to have your transmission and the controller checked.
