FTM =the devil

[killcrap]

If the tire pressures are ok, and not influenced by ambient temperatures, and there are no issues with the alignment or steering angle sensor, and there are no faults stored in the DSC, then the following statment may be the cause of your FTM issue.

On vehicles with front and rear air suspension, a CAN error can set the TPM malfunction lamp on, interrogate the fault memory, and see if there is a fault stored in the EHC module for a CAN fault. Perform the test plan, and it will state to replace the EHC module with the latest coding index of 23

It is likely some sort of fault because everything else is operational.

So is the ehc unit bad or just needs to be recoded? The previous owner informed me that he had the ehc replaced recently so I am hoping that it is not dead.
