If the Pcm sets a code saying that it's companion has dtc, you need to check the Ecm because it will have a code in it.

Either the PCM, or ECM will have another code in it. Diagnose and repair that code and the companion dtc set code will go away.Either the PCM, or ECM will have another code in it. Diagnose and repair that code and the companion dtc set code will go away.
Trouble code P1693 means: A companion DTC was set in both the ECM and PCM
Trouble code P1693 means: A companion DTC was set in both the ECM and PCM
P1693 : DTC in companion module.You need to check for codes in other computers (pcm or ecm) and repair their causes and then this code will clear itself.P1693 : DTC in companion module.You need to check for codes in other computers (pcm or ecm) and repair their causes and then this code will clear itself.

P1693 : Dtc detected in the companion module. You need to check the Ecm and Pcm for codes. Which ever did not have p1693 will have a code.
The ecm and pcm will each set that code if the other has set any other codes.

P1693 means that there is a code in the companion module. The pcm and ecm are the companion modules.
The engine computer (ECM) ( on the driver side of the block ) and the powertrain computer (PCM) ( on the passenger side of the firewall ) are the companion modules.
