Engine/Transmission (1998.5 - 2002) Code P1693

[Frank Marquet]

I have a 99 Dodge 2500 and I have a code P1693 which just tells me there is a fault set in the ECM.I have a DRBIII and that's all it tells me. I need to know where to go from here

P1693 is considered the “companion code”. There might be another code with it...

Any symptoms...truck mods'?

 

[Frank Marquet]

If there is another code with it it is not showing up on my DRBIII. There are no symptoms. the truck runs fine. The speedo wasn't working so I replaced the rear wheel ABS sensor and now the speedo works. the truck has a tuner on it and I removed the tuner and that didn't do anything. when I try to clear the code the DRBIII says request denied.

I think it is the other way around. The P1693 says an error in the companion module IE the PCM.

Ok so where do I go from here

When I try to erase it I get a screen that says request denied and how do I get to the powertrain verification test

How do I get to the ECM which is on the engine through the DRBIII

Smarty Tuner sets this code too, you can ignore it as a glitch. Like said, it's a companion, as it comes on its own and alone = no problem.

I had that code for 10 years on my 2001.5 along with a couple other the DTT transmission threw.

Yeah, I figured that out when I connected Autoenginuity to my buddies '99, the Electonics in the second Gen are pretty basic and not of great help. As long as it runs fine, ignore the rest.

Thanks for the suggestions. The MIL light went out on its own. I guess it fixed itself HAHA

Like I said, pretty basic computer.

I've had that code for the 15 years or so I've had a Smarty. No issues.
