What You'll Learn
Resetting the chair by tilting it back and then forward
The underlying cause of the problem may be a faulty "end switch" position sensor. This can be due to a lack of continuity in the circuit going to the main control board. It is possible to bypass this switch by connecting the two wires of the circuit with a crimp connector or electrical tape. However, this will disable the turtle mode safety feature, which slows down the chair when the seat is reclined to make it more stable.
Another possible solution is to reset the wheelchair by holding buttons 3, 5, and 6 together and turning on the chair. While the buttons are flashing red, press button 4 twice, and the wheelchair will reset itself.

Kicking the side of the chair
Turtle mode can be triggered by various factors, such as changes in the chair's angle or issues with the magnetic locks. In some cases, simply tilting the chair back and forth can reset it. However, if the chair frequently enters turtle mode, kicking the side of the chair may be the fastest way to reset it. This method was shared by a user whose daughter's Numotion Permobil M300 powerchair experienced frequent issues with turtle mode.
It is important to note that entering turtle mode can be a safety feature designed to slow down the chair when it is reclined beyond safe operating angles. In some cases, the issue may be related to a faulty "end switch" position sensor or a circuit problem. If kicking the side of the chair resets it, it may be worth inspecting the wiring and switches to identify any potential faults.
While kicking the side of the chair can be a quick fix, it is important to address any underlying issues with the powerchair to prevent frequent occurrences of turtle mode. Consulting a technician or seeking professional repair services may be necessary to ensure the safe and proper functioning of the powerchair.
Additionally, it is worth exploring other methods to reset the chair, such as holding down specific buttons or checking the brake release lever. In some cases, issues with turtle mode may be related to problems with the tilt actuator or position sensor, which may require further investigation and repair.

Locking and unlocking the brakes
If your Permobil M300 wheelchair is stuck in turtle mode, it may be due to a problem with the solenoid brakes. This can be caused by knocking the brake release lever on the motor. To resolve this issue, try locking and unlocking the brakes a few times.
The M300's braking system is designed to provide safe and reliable stopping power. The solenoid brakes are controlled by the power module, which detects any problems with the brakes or their connections. If a problem is detected, an error code will be displayed on the controller, such as "M1 Brake Error" or "M2 Brake Error".
To lock the brakes on the M300, locate the brake release lever on the motor. This lever should be in the "unlocked" position when the wheelchair is in use. To lock the brakes, simply move the lever to the "locked" position. This will prevent the wheelchair from moving, even if the joystick is operated.
To unlock the brakes, simply move the brake release lever back to the "unlocked" position. It is important to ensure that the brake release lever is in the correct position before attempting to operate the wheelchair. If the brake release lever is knocked or moved accidentally, it can cause the wheelchair to become inhibited, resulting in the turtle mode error.
In addition to checking the brake release lever, it is also recommended to inspect the solenoid brakes, cables, and connections to the control system. If the problem persists, the power module may be defective and may need to be replaced.

Checking the solenoid brakes, cables and connections to the control system
To check the solenoid brakes, cables, and connections to the control system of your Permobil M300, you can follow these steps and guidelines:
First, let's understand the function of the solenoid brakes and the control system. The Anti-lock Braking System (ABS) and Electronic Stability Control (ESC) systems in vehicles play a crucial role in ensuring safe and efficient braking. The ABS computer or Hydraulic Control Unit (HCU) is a critical component that regulates brake pressure during normal operation. Inside the HCU are valves and solenoids that control the pressure to each wheel.
To check the solenoid brakes and related components:
- Inspect the HCU for any signs of damage or corrosion. Look for any debris, corrosion, or contaminated brake fluid that could cause issues with valve seats and pintles.
- Test the solenoids electrically. A solenoid typically has a resistance between 2 and 8 ohms. If a solenoid is stuck or defective, it may set a code that can be scanned and diagnosed.
- Check the inlet and outlet valves for any issues. A stuck open inlet/isolation valve will affect the ABS system, while a stuck open outlet/dump valve in one circuit can cause a loss of brake pressure at a wheel, leading to a pull condition during normal braking.
- Pay attention to any unusual behaviour during braking, such as a "kick back" or pulsation in the pedal, which could indicate solenoid or pump issues.
Now, let's discuss the cables and connections to the control system:
- Ensure that you are using high-quality cables. The quality of the cable significantly impacts the performance of your control system. Choose cables that meet the required specifications, such as gauge, voltage, and temperature limits.
- Understand the different types of cables used in your system. For example, access control systems use various cables, including low voltage power cables, network cables, and control cables.
- Properly install and route the cables. Follow wiring diagrams and guidelines provided by the manufacturer. Incorrect cabling can lead to issues with lock power, reader power and communication, request-to-exit buttons, and more.
- Test your system after installation. It is crucial to identify any potential issues with the cables, connections, or control system before they become more significant problems.
Remember to consult a qualified technician or refer to your specific device's manual for detailed instructions pertaining to your Permobil M300.
