Error code 11: Incorrect phase current A
Description: Error code 11 is most often linked to problems with phase current A (blue) and is caused by moisture and corrosion.
Measure: Inspect phase A on the motherboard. If moisture ingress or corrosion is detected, correct these issues to restore normal operation.
Error code 12: Incorrect phase current B
Description: Error code 12 is most often linked to problems with phase current B (brown/black) and is caused by moisture and corrosion.
Measure: Inspect phase B on the motherboard. If moisture ingress or corrosion is detected, correct these issues to restore normal operation.
Error code 13: Incorrect phase current C
Description: Error code 13 is most often linked to problems with phase current C (yellow) and is caused by moisture and corrosion.
Measure: Inspect phase C on the motherboard. If moisture ingress or corrosion is detected, correct these issues to restore normal operation.
Error code 14: Faulty throttle control
Description: Error code 14 is most often linked to problems with the throttle control and its cable.
Measure: Check the throttle, display unit and cable connection. The throttle contains two magnet poles that may need to be adjusted if they have separated due to shock or vibration.
Error code 15: Incorrect brake management
Description: Error code 15 can occur due to problems with the brake lever and its cable.
Measure: Inspect the brake lever, display unit, and cable connection. The brake lever also contains two magnetic poles that can be damaged by impact or corroded by water contact.
