🚨 Bobcat Keyless Panel isn’t working — Intermittent Shutdown, Error 34-04, B>D Symbol 🚨

One of the first signs of a failing RH Keyless Panel is the well-known 34-04 error.

🔧 Common symptoms:
• Machine shuts off when bumped or vibrates
(acts like the STOP button was pressed)

• When pressing the RUN button, the display appears fuzzy or distorted, then immediately shuts off

• RH panel shows the B>D symbol

• Pressing the RUN button causes both panels to light up briefly, then die immediately

🛠 Diagnostic Tip:
If the machine will not start, try holding the RUN button.
In many cases, the LH display will show the 34-04 error code.

⚠️ Important:
If you press the RUN button and NO panels light up at all, the issue may NOT be the RH panel alone. Possible causes include:

• LH panel malfunction
• Power supply issues (damaged/broken wiring)
• Main controller failure
(often also causing the B>D message on the RH panel)

✅ However, if your machine behaves like the symptoms described above, there is a very high chance the RH Keyless panel requires repair.

At ISOSCELL, we professionally test and refurbish Bobcat panels and controllers using dedicated test stands.

If you need assistance with diagnostics or repair, feel free to contact us.

BICS controller not working – What Most Owners Don’t Know

Many machine owners struggle to determine whether a controller is actually faulty. Here’s a simple breakdown to help you better understand the system behavior:

1️⃣ Traction Not Activating (No BICS Light, No Blinking)
If the traction function does not engage and the BICS light is OFF (no blinking error), the issue is typically not the BICS controller itself.
👉 In most cases, the BICS controller is not receiving the RPM signal.

2️⃣ Lift/Tilt Not Activating (No BICS Light, No Blinking)
If lift and tilt functions do not respond and the BICS light is OFF (no blinking error):
👉 The BICS controller is not receiving the READY signal from the AHC controller.

How the System Works:
The AHC system must pass a self-test before enabling functions. This includes:
• Actuator verification
• Hand sensor neutral position check

✅ Only after a successful test will the AHC send a READY signal to the BICS controller.

Important:
• If the AHC system has an issue, errors will usually appear on the left handle (blinking led)
• The BICS controller may still show lift/tilt errors, especially on machines without AHC

⸻

⚠️ Conclusion:
In many cases, the controller is wrongly blamed. The real issue often comes from missing signals (RPM / READY) rather than a defective unit.

⸻

If you’re unsure, we can test and diagnose your BICS controller accurately before replacing expensive parts. Also, we can repair it
