What is error code 30?Updated a month ago

Error 30 refers to a communication error that can be caused by any of the bike's electrical components. Follow this step-by-step guide to identify the source of the issue. If you experience any unexpected results, stop and contact Ariel Rider tech support at [email protected].

Important Safety Note

Whenever performing any maintenance or service, always Dissipate Controller Energy (DCE) by:

• Removing or powering off the battery.

• Holding the Power button on the display keypad for 5 to 10 seconds.

• 
  

Step 1: Initial Power Cycle(DCE)

1. Remove the battery from the bike.

2. Dissipate the energy in the controller by holding the power button on the display for 5 to 10 seconds.

Step 2: Basic Configuration Testing

To isolate the issue, perform the following checks using the Basic Configuration setup:

1. Ensure that only the main cable assembly and XT60 battery connector are connected.

   • Do not connect the motor cable connector.

2. Disconnect all connectors in the cockpit (throttle, brake cutoffs, headlight, display).

3. Only the display should be connected to the main cable assembly.

4. With the battery installed, power up the bike using the display keypad.

   • The display should show an Error 08 code, indicating proper communication.

If Error 30 persists, the display, tree cable, or controller may be at fault. Contact tech support.

Step 3: Reconnecting Components One by One

After confirming basic communication, begin reconnecting components one at a time, power cycling the bike after each step to check for errors.

1. Reconnect the motor cable.

   • Power on the bike and verify no errors.

   • Test walk mode by holding down the minus (-) button on the display/keypad.

   • If Error 30 appears, stop and contact tech support.

2. Reconnect the throttle.

   • Power cycle the bike and verify throttle operation.

   • If an error appears, disconnect and proceed to the next step.

3. Reconnect the cadence sensor (near the bottom bracket).

   • Ensure the motor cable is clear of the brake rotor before testing.

   • Power cycle the bike and test if the cadence sensor is working.

   • If the motor does not engage or an error appears, stop testing immediately and contact tech support.

4. Reconnect the lighting system.

   • Connect the headlight and power cycle the bike to test function.

   • Repeat for the taillight.

5. Reconnect the brake cutoffs and verify operation.

6. Reconnect additional accessories (e.g., motor selector switch on Grizzly models) and test.

If at any point an unexpected error occurs, stop and contact Ariel Rider tech support at [email protected].

Basic Configuration Overview

Basic Configuration consists of the minimum components needed to allow the motor to function without errors on the display:

• Motor

• Controller

• Wiring Harness

• Display

This is the starting point for diagnosing Error 30 and No Motor Power issues. It is also the recommended initial setup when testing a new controller.

Important: Disconnect all lights, extension cables, switches, cutoffs, the throttle, the pedal assist sensor, and any other accessories (e.g., phone charger). This prevents damaged cables from causing unexpected issues.

Bike-Specific Disconnections

X-Class / Kepler

At the Controller:

• Disconnect the Tail Light Extension Cable at the controller (rather than disconnecting the taillight itself).

• Disconnect the Pedal Assist Sensor (Cadence Sensor).

• Disconnect the Headlight Switch Harness (if equipped).

At the Handlebars:

• Disconnect the Brake Cutoffs.

• Disconnect the Headlight.

• Disconnect the Throttle.

Grizzly / D-Class

At the Controller:

• Disconnect the Pedal Assist Sensor Extension (Cadence Sensor).

• Disconnect the Taillight.

• Disconnect the Motor Selector Switch.

• Disconnect the Battery Detection Module (G3 models only).

• Keep the Master/Slave communication connected between the two controllers.

Older D-Class Models Only:

• Disconnect Brake/Motor Cutoffs.

• Disconnect Headlight.

• Disconnect Throttle.

At the Handlebars:

• Disconnect Brake/Motor Cutoffs.

• Disconnect Headlight.

• Disconnect Throttle.
