Basically, the 1693 is simply a "flag code" allerting you there is another (or more), possibly serious, fault code deeper inside the ECM. Switch the ignition on, and then off again WITHOUT starting the engnine, 3 consequetive times, and any other codes (Pcodes) held in the ECM will scroll across the display - write them down, and we can tell you what they indicate.

The 1693 code stands for DTC Detected in Campanion JTEC Module.

I've had that code for 2 years??? No trouble yet!!!

The 1693 code stands for DTC Detected in Campanion JTEC Module.

In practical terms, that 1693 code is much like the flag on a mailbox - when it's in the "up" position, it alerts someone that there's something in the box - the 1693 code itself doesn't isolate or indicate ANY *specific* problem.

OK... . I also had a PO500: Vehicle speed sensor malfunction???[what is this]

and a PO217: Engine overtemp condition. . I hauled a D2 5U bulldozer from Utah to Tulsa OK. and did get her hot in the mountains.

Now what is the Veh. speed sensor??

How or can I clear these codes? Will disconnecting and "shorting" Batt. cables do it?

THANKS!!!!
