Kia Troubleshooting Questions? Ask a Mechanic
Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
Have any repairs been done on your vehicle recently at all that may have caused this issue possibly?
Let me know so we can continue,thanks Pete.
And if you clear out all of these codes do they all come right back again?
These are circuit codes here.This can be a fault with the TCM itself needing replaced or possibly a wiring issue from the TCM to the transmission electronics.I would follow one of the diagnostic charts for these codes to see if it points to the TCM at fault needing replaced.Below is the flow diagnostic chart for the P1800 to follow.
If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service.You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.
Your welcome.I suspect you will most likely find a faulty TCM needing replaced.
Let me know if you need anything else and feel free to rate my help here.
In most cases I havent seen this myself but it is possible it can short out and back feed damaging the TCM so it is possible but not very likely.
It may be a data communication fault due to the TCM failure here as this can cause other components like the fuel pump issue to keep from starting the engine to prevent any damage to any components in the engine or transmission.
I apologize for the delay.
Is this a spectra GS or GSX?
The part number for your model is k2ab189e0b.It looks like the correct part number you shown here is the right part and it may be used on two different models.
Yes it does need to be calibrated with a dealers GDS machine after it is replaced.This has to be done in order for it to operate properly in your vehicle here.
I did now I apologize as we got into the TCM part number and didnt see the request for the diagram.Unfortunately this is a huge list of wiring that I am unable to post here.You can get the complete diagram of this model as well as diagnostic and repair info for a complete year at https://www.alldatadiy.com/.
You should be able to get all the wiring info you need there on this model.They do charge a small fee for it but its good for one year for all repair and diagnostic info including diagrams for your vehicle.
Feel free to rate my help here as this is how I receive credit for my time.
Unfortunately the ECM would need to be programmed by a dealer to match your VIN here.If this is not done all other computers in your vehicle will have some issues and may not allow starting or proper operation.
