Blink Code 30

Yamaha Motorcycle

Severity: Moderate

What Does This Error Mean?

Blink code 30 on a Yamaha motorcycle means the lean angle (tip-over) sensor has detected the bike beyond the safe lean angle, or the sensor itself has a fault. The bike refuses to start. Set the bike upright, cycle the ignition off and on, and try restarting. Persistent blink 30 needs sensor inspection.

Affected Models

  • Yamaha YZF-R1
  • Yamaha YZF-R6
  • Yamaha MT-07
  • Yamaha MT-09
  • Yamaha FZ-09

Common Causes

  • Bike has fallen over or laid on its side (sensor working as designed)
  • Failed lean angle sensor (internal wear)
  • Sensor mounted incorrectly after fairing removal
  • Loose sensor connector after vibration
  • Damaged sensor wiring

How to Fix It

  1. Set the bike fully upright.

    If the bike has fallen, set it back on the side stand and ensure it is upright. Walk away for a minute to let the sensor reset.

  2. Cycle the ignition.

    Turn the ignition off completely, wait 10 seconds, then turn it back on. The lean angle sensor self-tests on each ignition cycle.

  3. Inspect the sensor mount.

    On most Yamaha bikes the sensor is under the seat or behind a side panel. The arrow on the sensor must point UP. A sensor mounted upside-down or sideways triggers blink 30 immediately.

  4. Check the sensor connector.

    Disconnect and look for corrosion. Reseat firmly. Apply dielectric grease to prevent future moisture issues.

  5. Replace the sensor if blink 30 persists.

    Yamaha lean angle sensors cost USD 80–150. Replacement is straightforward — unplug, unbolt, fit new, plug in. Most riders complete in 20 minutes.

Frequently Asked Questions

Why did blink code 30 appear without my bike falling over?

If you parked on a steep gradient or accidentally pushed the bike past 60° lean while moving in the garage, the sensor may have activated. Set fully upright and retry. Persistent blink 30 with normal handling means the sensor is faulty.

Can I bypass blink code 30?

Strongly discouraged. The lean angle sensor is a safety feature — it kills fuel and ignition when the bike falls, preventing fuel pump operation while you may be injured. Bypassing creates a fire risk. Repair the sensor instead.
