C6734

[HParfitt]

Hi,

I changed my oil, oil filter, and fuel filter yesterday. As part of recording the maintenance, I was checking eng hours, I notice a C6734 code on the odometer read out. I have no mil light. I can't find any info on this code. Anybody have any ideas? The truck is an 04. 5 4X4 6spd. The truck is stock except for a roteck crank sensor. Just thought I would mention it even thou it's a chasis code.

It's not a fault code, they all start with "P" and they don't go that high number wise.

Maybe a software rev?

Just a guess, but were the 67 and 34 separated? 'C' code 67, 34 key cycles since that code was thrown. It would be a guage cluster code. I think that they are listed in the service manual. I don't have mine with me right now so I can't check it. Hopefully someone else will.



Edit: Page 8J-13 in the 2004 manual. Fault Code 67: All door unlock output circuit shorted to ground or voltage.



Not sure what it means or what to do about it.
