How to Fix / Troubleshooting
Safety: Turn OFF and disconnect the battery before working on the drive system.
- Inspect right motor: Check the right drive motor housing for cracks, rust, or impact damage.
- Cable check: Inspect the right motor cable along its full length for cuts or crushed sections.
- Swap test: If possible, swap left and right motor connectors at the mainboard to see if the error follows the connector or stays with the motor.
- Electrical test: Measure resistance across the right motor terminals. Abnormal readings indicate a faulty motor.
- Replace the right drive motor assembly if defective. If the motor is fine, the mainboard motor driver may be faulty.
