Blink Code 30
Yamaha Motorcycle
Severity: ModerateWhat 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
-
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.
-
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.
-
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.
-
Check the sensor connector.
Disconnect and look for corrosion. Reseat firmly. Apply dielectric grease to prevent future moisture issues.
-
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.
