Yamaha SuperJet (4-Stroke, from 2021) Fault Codes: List
The SuperJet with the TR-1 four-stroke has a simply built control unit without a shift system. M-JET DIAGNOSTIC reads around 35 messages and explains them.
The most important codes
- 13 pulser coil, 15 engine temperature, 19 battery voltage
- 23 intake air temperature, 24 camshaft, 29 intake pressure, 63 intake system
- 47 slant switch, 55 steering sensor, 65 exhaust manifold water temperature
- 51 throttle lever closed-position switch, 124 to 128 TPS, 131 to 135 APS
- 112 to 145 throttle valve drive
Less electronics, clearer answers
The SuperJet has neither RiDE nor reverse, so the list is manageable. The slant switch (47) is especially relevant on a stand-up because of frequent falls. For every code the app shows the symptom and the check steps you can do at the jetty.
Note on numbering: the codes come from the control units' diagnostic database, as the diagnostic tool reads them. Forums and manuals partly circulate different assignments, especially for older models and for codes shown on the display. When in doubt, the description in the app counts.
