Default Hello to all

I'm getting the dreaded abs/traction signals. Also, 2 of my tires are giving me the under inflated signal, even though I KNOW that they are filled to spec. When I pull the codes to post here, are there certain codes that I should be looking for so that I can post them here? Before I have my computer fixed, I want to be sure all of the connections/fuses etc. are ok.





Thanks

Default Thanks so much.

This is going to sound stupid...but.. I tried pulling the codes but they flash so fast that I can't write them down.

I did get this though,
28 tcs no comm
hvac no comm

Post ALL your codes including the H or C or HC that follows each 5 character code. If you have any Unnnn codes then list the sensor under which the Unnnn code appears. For example 28-TCS U1016.


The same Unnnn codes can appear under multiple sensors and it is helpful to know which sensor the Unnnn code is associated with.




After you have recorded all the codes, CLEAR all of them and then take the car for a ride. When you return pull all the codes again BEFORE you shut off the ignition. THe codes that have returned are the ones you need to be concerned about fixing.

To pull code with the engine running you may need to use the reset button to clear any messages displayed in the DIC. Then pull the codes as above.
