Yamaha JetBlaster (from 2022) Fault Codes: List

The JetBlaster has a modern control unit with almost 50 messages. M-JET DIAGNOSTIC reads them and explains each in plain text.

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, 51 throttle lever closed-position switch, 55 steering sensor
• 65 exhaust manifold water temperature
• 150 to 154 RPS and 157 to 164 SCU (on variants with RiDE)
• 112 to 145 throttle valve drive, 124 to 128 TPS, 131 to 135 APS

Classification

The list is broad because on variants with RiDE the control unit also monitors shifting. Even on young vehicles, connectors, ground and voltage are the most frequent causes of an entry. Check these first before ordering a part. For every code the app shows symptom and check steps.

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.
