Bobcat code M1706: Hydraulic lock valve short to ground
What it means
The hydraulic lock valve solenoid circuit is shorted to ground. This valve locks out loader hydraulic functions.

Stop: fix before runningNo. Stop the machine safely (bucket or attachment down, engine off) and find the cause before you run it again.
Check first
- Park on level ground, lower the lift arms and attachment to the ground, stop the engine and remove the key.
- Inspect the lock valve wiring for rub-through against the frame.
- Restart and see if the code comes back. If it does, stop and call your Bobcat dealer.
- Do not bypass or modify the seat bar, BICS interlocks or parking brake to keep working.
Likely causes
- Chafed wire touching the frame
- Water in the connector
- Failed solenoid coil
The fix
