YAMAHA Motorcycle Fault Codes DTC

Below you can see methods of diagnostics, Yamaha fault codes DTC, troubleshooting.

 

To begin with, a few words about indicating fault codes DTC.

 

There is a CE (Check Engine) lamp on the nozzles of the injectors, when errors occur, with its help the system will let you know about the malfunctions. Indication is of two types: the lamp blinks, or the lamp burns continuously.

 

Simultaneously with this in the field of the odometer should light up the two-digit code corresponding to the error. If there are several faults, they will be displayed sequentially.

 

If the lamp blinks, the system detected an error, due to which starting the engine is not possible. This happens with error codes 12, 19, 30, 41 and 50 (deciphering codes see below)

 

If the lamp burns continuously, it is possible to start the engine (not in all cases), however, it should be remembered that the system will operate in emergency mode, in some cases further operation may lead to serious problems, so you need to deal with the problem as quickly as possible.

 

Note: Immediately after switching on the ignition, during the diagnostic cycle (blow with all arrows) the lamp lights up for 1, 4 sec. This is not a mistake, and serves to check the efficiency of the lamp itself.

 

Next. All injectors have their own diagnostics and testing sensors on board, many also have adjustment.

 

In this case, test and error codes are similar between different types of technology and one and the same test or code means the same for example. snowmobile VK 540 and sports motorcycles YZF-R1.

 

Enter diagnostic mode.

 

— Turn off the ignition, start/start button (red key on the right remote) in position ON.

— In this case, according to the manual, it is necessary to disconnect the power cable from the fuel pump (under the drain).

— Press the RESET and SELECT buttons on the instrument panel.

— Turn on the ignition without releasing the button, wait for about eight seconds until the device is on. Panel "DIAG" will not appear. Release the buttons

 

At this stage you can switch between testing and setting by pressing the SELECT button for a couple of seconds (Setting on 3-m generation is missing! )

 

— Next, when the inscription "DIAG" appears on the screen, press the buttons RESET and SELECT for two seconds.

— Button setting/locking in position OFF.

 

Before you is the injector diagnostic mode.

 

Attention! Do not switch between tests when the engine stop/start key is in ON position.

 

This key in diagnostics is responsible for starting the test, and should be moved to the ON position only if you want to conduct the test.

 

Always switch between tests when the key is in OFF position!

Testing of Yamaha motorcycles and snowmobiles:

 

You can switch between tests using the RESET and SELECT buttons. The general meaning of the test is the same throughout the technique, and here are some nuances of the test, namely the value of the sensors shown (for example, the percentage of position of the throttle valve) — may differ - check the data in the service manuals of your equipment.

To run the test you need Move the start/stop engine key to ON position, to stop the test and proceed to the next test - to OFF position.

 

d01 = position of the throttle valve (tight gas handle) (at the moment the throttle is completely closed, it should be shown, 2-3 generations: 15-16, 4+ Generation 14-20; Fully open, on 2-3 generations: 97-102, on 4+ generations: 97-107)

 

d03 = discharge in inlet (sensor in air body) filter, in percentage) (Tmax - thin hose on the inlet collector, creating a discharge, for example, with a syringe, or with a twist starter and look)

 

d05 = inlet air temperature (sensor in the air filter body)

 

d06 = temperature of coolant (sensor near thermostat)

 

d07 = sensor speed (shows the number of pulses at the moment of starting the test key stop-motor; tilt forward wheel - look)

 

d08 = voltage at the output of the fall/inclination sensor (at Tmax two variants without gradients; horizontally: 0. 4-1. 4v; at inclination 45-65°: 3. 8-4. 2v)

 

d09 = voltage at the fuel pump (actually - voltage at the mains in the absence of problems; tested with the stop-motor key)

 

d20 = side skirt (on/off, fold/fold the skirt and look)

 

d30 = ignition coil (when stop-motor key is included) Testing of the coil is carried out with 5 pulses, accompanied by a characteristic sound, with one pulse Lamps Check Engine )

 

d36 = nozzle of 1 cylinder (when the stop-motor key is included, testing of nozzles is carried out on 5 impulses, Accompanying the characteristic sound, with Lamps Check Engine )

 

d37 = nozzle of 2 cylinders (produced when the stop-motor key is included) Testing of nozzles on 5 pulses, accompanied by a characteristic sound, with Lamps Check Engine )

 

d50 = power relay of injector and system Ignition (tested in the same way as the stop-motor key)

 

d51 = relay inclusion of cooling fan (tested with the same key stop-motor)

 

d52 = head light relay (tested in the same way as the stop-motor key)

 

d57 = relay heating handle (option, connects to yellow-black wire plugs)

 

d60 = on Tmax - EEPROM fault code, when errors occur 44. ("00" - if there are no errors, "01" or "02" - cylinder, on which caused the error, if more than one - changes every 2 seconds)

 

d61 = history of errors recorded in memory ("00" - if there are no errors, if errors more than one, will change in a circle every 2 seconds)

 

d62 = number of errors in history (00-17) / erasure of errors from history (key stop-motor)

 

d63 = fault code for error code №24, appeared since the 4th generation

 

d70 = reflects working code program (0-255)

 

Er1 = no signal from engine control block

 

Er2 = no response from the engine control block in the expected period time.

 

Er3 = error signal from engine control block

 

Er4 = unknown signal from engine control block

 

Tests d60-d63 allow View errors in memory, and also delete them if necessary. Also, the current error code (if there is an error) usually appears a few seconds after turning on the ignition, along with blinking. lamps SE .

There are Yamaha motorcycles Injector error codes:

 

12 = no signal from the crankshaft position sensor

13 = no signal from the absolute pressure sensor, or a short circuit in its circuit was detected.

14 = incorrect signal from the absolute pressure sensor (the tube is disconnected or clogged) (on Tmax - a thin tube on the intake manifold, and the sensor itself is slightly higher on the frame)

15 = throttle position sensor error (open or short circuit on Tmax)

16 = throttle position sensor jamming error

19 = short circuit in the side stand circuit

21 = coolant temperature sensor malfunction

22 = air temperature sensor malfunction (in the intake)

24 = O2 sensor (oxygen sensor) is inactive, no normal signals came from the O2 sensor. On Tmax 4+, when this error appears, look for an extended fault code in test d63.

30 = Tilt/Drop Sensor Detected (Motorcycle has been dropped or Sensor is faulty/incorrectly installed; see Test D08)

33 = Ignition Coil Control Wire Shorted

37 = Starting Enrichment Valve Stuck Open. (Symptom: high idle speed after warming up. The valve is located on the bottom of the throttle body. )

41 = no signal or short circuit on the tilt/dip sensor (see test d08)

42 = no or erroneous signal from the speed sensor (see test d07)

43 = error measuring voltage in the fuel system (short circuit in the wiring (red-blue wire), fuel pump relay malfunction, see test d09)

44 = error reading or writing the EEPROM of the unit (ECM malfunction; CO value is incorrectly written / read to / from the internal memory; see test d60). Worse than this, only error 50.

46 = no voltage on the injector unit

50 = engine control unit error, it is impossible to read the error. If you have it - pray! :)

 

Immobilizer error codes:

51 = key code not received by immobilizer

52 = key and immobilizer codes do not match

53 = ECM did not receive key code from immobilizer

54 = immobilizer and ECM codes do not match

55 = key code registration failure (when registering a new working key)

56 = ECM did not recognize the key code

 

By the way, the service manual has a table listing error codes with instructions on where to look if they appear.

 

Also keep in mind that almost any sensor that is causing the error can be tested, and during the test you can hear the relays and drives being tested. And do not forget that the error can be hidden not only in the sensor itself, but also in the sensor connector, in breaks and short circuits on the wiring harness.
