CAT 262D3 Speed Sensor Codes

Mr. Wrench · 2026-06-01 12:58

I'm looking for the wiring diagram for a CAT 262D3 s/n DTB07427. It has wheel speed codes 2685-8 and 2686-8. I have the diagnostic procedure for those codes just not the right wiring diagram. Haven't set eyes on the machine yet, but hope to work on it tomorrow.

    An update on this machine. It ended up being a broken sensor power wire on the sensor side of the plug.

    Thanks for letting us know what was the cause. Simon C

    With there being two sensors in a common body if both are faulting at the same time it’s generally an issue with either the power supply or the ground.
