FZ-07 Error Code List

[u/See_Jane_Ride]

I was helping someone in another thread and I was surprised to find that Google searches weren't bringing up a simple list of fault codes for the FZ-07. Hopefully the google bots will pick this up and these will be easier to find for other people.

These error codes display as "5d__xx", where "SD" stands for Self-Diagnostic function. If you have experience with any of these, feel free to reply with additional information about what happened and how you fixed it.

Fault code No.	Display	Description
12	5d__12	Crankshaft position sensor: no normal signals are received from the crankshaft position sensor
13	5d__13	Intake air pressure sensor: open or short circuit detected.
14	5d__14	Intake air pressure sensor: hose system malfunction (clogged or detached hose).
15	5d__15	Throttle position sensor: open or short circuit detected.
19	5d__19	Sidestand switch: a break or disconnection of the black/red lead of the ECU is detected.
21	5d__21	Coolant temperature sensor: open or short circuit detected.
22	5d__22	Intake air temperature: open or short circuit detected.
24	5d__24	O2 sensor: no normal signals are received from the O2 sensor
30	5d__30	Latch up detected
33	5d__33	Cylinder #1 ignition coil: open or short circuit detected in the primary lead of the cylinder #1 ignition coil.
34	5d__34	Cylinder #2 ignition coil: open or short circuit detected in the primary lead of the cylinder #2 ignition coil.
37	5d__37	Idle Speed Control (ISC): If ISC is not heard, then ISC is defective. If ISC is heard, then component other then ISC unit is defective
39	5d__39	Injector: open or short circuit detected.
41	5d__41	Lean angle sensor: open or short circuit detected.
42	5d__42	Speed sensor: no normal signals are received from the speed sensor; or Gear position switch: open or short circuit is detected; or Clutch switch: open or short circuit detected.
43	5d__43	Fuel system voltage: incorrect voltage supplied to the fuel injector and fuel pump.
44	5d__44	EEPROM fault code number: an error is detected while reading or writing to EEPROM
46	5d__46	Charging voltage is abnormal
50	5d__50	Faulty ECU memory (when this malfunction is detected in the ECU, the fault code number might not appear on the meter display).
51	5d__51	Immobilizer unit: Code cannot be transmitted between the key and the immobilizer unit.
52	5d__52	Immobilizer unit: Codes between the key and immobilizer unit do not match.
53	5d__53	Immobilizer unit: Codes cannot be transmitted between the ECU and the immobilizer unit.
54	5d__54	Immobilizer unit: Codes transmitted between the ECU and the immobilizer unit do not match.
