Bobcat M7002 (70-02) Fault Code: Switched Power Output Error On
Also shown on the panel as 70-02 · Also called Switched Power Output Error on
Switched Power Output Error On · ai-assisted, editor-reviewed · Last updated 2026-07-13
TL;DR
M7002 (panel code 70-02) sets when the gateway controller sees voltage on the switched power output wire (3380 or 8000, depending on machine) when it did not command that output on. It only sets with the key switch in the run/enter on position. The usual cause is a short to battery voltage on that output wire, a bad gateway controller, or corrosion and pushed-back pins in the connectors.
Medium severity. M7002 does not directly disable a drive, lift, or engine function by itself, but it points to a wiring or controller fault in the switched power circuit that can cause unpredictable electrical behavior. It should be diagnosed before the next work shift rather than ignored.
What does Bobcat error code M7002 mean?
M7002, shown on the panel as 70-02, is a Switched Power Output Error On fault. The gateway controller manages a switched power output circuit, wired as 3380 on some machines and 8000 on others, that is supposed to be off unless the controller commands it on.
This code means the controller is seeing voltage on that output wire even though it never told the circuit to turn on. In other words, power is getting onto that wire from somewhere it should not be coming from, most likely a short to battery voltage further down the harness.
This condition is only checked and only sets while the key switch is in the run/enter on position. If the fault is intermittent, it may not be present when a technician checks it with a diagnostic tool, which can make it harder to track down.
Common causes of M7002
- Controller output wire 3380 (or wire 8000 on machines using that circuit) shorted to battery voltage somewhere in the harness.
- A fault in the gateway controller itself.
- Moisture, corrosion, or pushed-back pins in the gateway controller connectors, the switched power relay connectors, or the mainframe harness connectors.
- Intermittent version of the same problems: loose connections, corrosion, pushed-back pins, the controller, the wire harness, or some combination of these, which may not be present or found at the time of testing.
How to troubleshoot Bobcat M7002: first checks
- With the key switch on, check for the code and note whether it is currently active or only stored, since an intermittent fault may not show voltage at the time of testing.
- Inspect the gateway controller connectors, the switched power relay connectors, and the mainframe harness connectors for moisture, corrosion, or pins that have been pushed back out of their normal seated position.
- Trace wire 3380 or wire 8000 (whichever applies to the machine) for chafe points, pinched sections, or contact with battery-voltage wiring that could cause a short to battery voltage.
- Wiggle-test the harness and connectors near the gateway controller and switched power relay while watching for the code to trigger, since intermittent faults often need movement or vibration to reproduce.
- If wiring and connectors check out clean, suspect the gateway controller itself as the source of the false voltage reading.
How the code clears
Once the wiring or connector problem is repaired, or the controller is replaced if that was the cause, clear the code by cycling the key switch power off and back on.

Frequently asked questions
What does Bobcat code M7002 mean?
It means the gateway controller detected voltage on its switched power output wire (3380 or 8000 depending on the machine) when it had not commanded that circuit on, while the key switch was in the run/enter on position.
Is M7002 the same as panel code 70-02?
Yes. 70-02 is the numeric panel display form of fault code M7002 on affected Bobcat machines.
What usually causes M7002?
The most common cause is the output wire (3380 or 8000) shorted to battery voltage somewhere in the harness. Other causes include a failed gateway controller, or moisture, corrosion, or pushed-back pins in the gateway controller, switched power relay, or mainframe harness connectors.
Can M7002 be intermittent?
Yes. If the shorted condition or bad connection is not present when the machine is tested, the cause may not be found right away. Loose connections, corrosion, pushed-back pins, the controller, or the wire harness can all cause an intermittent version of this fault.
How do I clear M7002 after a repair?
Cycle the key switch power off and back on once the underlying wiring, connector, or controller issue has been repaired. No other reset procedure is listed for this code.
Which Bobcat machines can show M7002?
M7002 applies to the S510, S530, S550, S570, S590, S630, S650, S750, S770, T550, T590, T630, T650, T750, and T770, and T870.
Is it safe to keep operating with M7002 active?
Since the fault points to a possible short to battery voltage or controller problem in the switched power circuit, it is best to have it diagnosed before continuing normal work, since electrical faults like this can affect other circuits fed from the same controller or relay.
