Bobcat D7567 (75-67) Fault Code: No Communication From Gateway Controller
Also shown on the panel as 75-67 · Also called Drive No Communication from OEM Controller, No Communication from Gateway Controller
No Communication From Gateway Controller · ai-assisted, editor-reviewed · Last updated 2026-07-13
TL;DR
D7567 (panel form 75-67) sets when the Drive or Drive Plus controller loses CAN communication with the gateway controller. When this code is active, drive functions are disabled until the fault clears and the machine sees PTOL enabled.
High severity. Drive functions are disabled while this code is active, so the machine cannot be safely operated until communication is restored. It is not an immediate engine or fire risk, but it stops work and can leave the machine stranded.
What does Bobcat error code D7567 mean?
D7567 is a Bobcat controller communication fault. The Drive or Drive Plus controller talks to the gateway controller over a CAN bus, a two-wire network used to share data between control modules. On these machines the CAN high wires start with numbers 91xx or 95xx, and the CAN low wires start with 912xx or 96xx.
When the drive controller stops hearing from the gateway controller on this CAN link, it sets D7567 and disables drive functions as a safety precaution, since the controllers can no longer coordinate machine movement reliably.
This code applies across the S510, S530, S550, S570, S590, S630, S650, S750, S770, T550, T590, T630, T650, T750, T770, and T870 model lines, all of which use the same drive-to-gateway CAN architecture.
What triggers a Bobcat D7567 code?
The code sets whenever the key switch or run/enter switch is on and the drive controller cannot communicate with the gateway controller over CAN. No separate voltage, time, or count threshold is listed beyond this on-condition.
Common causes of D7567
- CAN communication wires (91xx/95xx or 912xx/96xx) shorted to supply voltage, shorted to ground, shorted to each other, or open
- A fault in the gateway controller itself
- A fault in the drive or drive plus controller
- Moisture, corrosion, or pushed-back pins in the drive/drive plus controller connectors, gateway controller connectors, or wire harness connectors
- An intermittent condition not present at the time of testing, which may involve loose connections, corrosion, pushed-back pins, a controller fault, the wire harness, or a combination of these
How to troubleshoot Bobcat D7567: first checks
- With the key switch or run/enter switch on, check whether D7567 is currently active or only stored as a history code
- Inspect the drive/drive plus controller and gateway controller connectors for moisture, corrosion, or pushed-back pins
- Trace the CAN high wires (91xx/95xx) and CAN low wires (912xx/96xx) for shorts to supply voltage, shorts to ground, shorts to each other, or an open circuit
- Check all wire harness connectors along the CAN path between the drive controller and gateway controller for loose or damaged terminals
- If the code is intermittent and not present during testing, wiggle-test connectors and harness sections while monitoring for the fault to reappear, since the cause may not be found on a single static check
How the code clears
No separate clearing procedure with steps is listed beyond the stated condition: once the repair is complete, the code clears when PTOL (the system enable condition) is enabled. In practice this means fixing the CAN wiring or controller fault first, then confirming the machine allows PTOL to enable before returning it to service.

Frequently asked questions
What does Bobcat code D7567 mean?
It means the Drive or Drive Plus controller has lost CAN communication with the gateway controller. Drive functions are disabled until communication is restored.
What is the panel display number for D7567?
The numeric panel form is 75-67.
Can I still drive the machine with D7567 active?
No. Drive functions are disabled while this code is active, so the machine should not be operated until the fault is diagnosed and repaired.
What usually causes D7567?
Common causes include shorted or open CAN wiring (the 91xx/95xx and 912xx/96xx wires), a failed gateway controller, a failed drive/drive plus controller, or moisture and corrosion in connectors and pins.
How do I know if the wiring or a controller is at fault?
Start by inspecting connectors for corrosion or pushed-back pins, then check the CAN high and CAN low wires for shorts to voltage, ground, each other, or an open circuit. If wiring checks out, the drive controller or gateway controller itself may need testing or replacement.
What if the code is intermittent and not showing up during testing?
Intermittent D7567 codes can be hard to pin down. Probable causes include loose connections, corrosion, pushed-back pins, a controller issue, the wire harness, or some combination of these, so a thorough wiggle test and connector inspection is worthwhile even if the fault isn't active.
How does D7567 clear once it's fixed?
The code clears once PTOL is enabled after the repair is completed. No separate reset procedure is listed.
