Check engine light

[cOoTeR]

Little late, but, your correct.
27 = Front wheel rotation sensor signal abnormal (sensor or rotor
missing, too large clearance, rotor tooth worn or missing,
wiring open)

49 = Return spring malfunction

Thank you.

Nevermind I'm pretty sure they are throttle return spring and wheel speed sensor. I tripped them on the dyno by doing a run without the wheel speed sensor disabled. Just did the reset procedure and it's gone.

Hi can you me tell whats the reset procedure for the Engine Check Light ?

Hi can you me tell whats the reset procedure for the Engine Check Light ?

From the service manual:

Service Code Erasing
• The service codes stored in memory of the ECU can be erased using Kawasaki Diagnostic System.
NOTE
*When erasing the stored service code memory, the accelerator position and throttle position initial
data of the throttle body are erased. Therefore, you must register the initial data to the ECU. Wait
the 10 seconds at the idle speed and the coolant temperature 40°C (104°F) or more to register
the initial data of the sensor position to the ECU.

*If the Kawasaki Diagnostic System is not available, do the following procedures.
1. Turn on the ignition switch and start the engine.
2. Keep the idling speed more than 30 seconds.
3. Run the vehicle more than 5 minutes at a speed of 40 km/h (25 mph) or more.
Be sure to keep the engine running during procedures 2 and 3 for more than 10 minutes in total.
4. Turn the ignition switch off.
5. Repeat the above procedures 3 times.
6. Start the engine and check that the yellow engine warning indicator light (LED) goes off.

Thankyou worked a treat

This is sidetracking a bit but still on the subject of error codes:

Those who've followed those steps described in the manual say it works fine but it'll quickly get old if you have a real problem that doesn't go away and keeps lighting up the CEL. In that situation it’d be useful to know what the problem is and be able to easily clear the error code once fixed. For those of us who do our own maintenance I'd say an OBD scanner is an essential tool for modern bikes (and cars).

Buying scanners for motorcycles can be a bit of trial and error. If you know the protocol used to communicate with the ECU then you can narrow down the list of available options. For our Kawasakis maybe a scanner that works on Toyotas would work. That’s a pure guess but might be a good place to start. A better place to start would be Woolich Racing website. They have a couple of scanners listed that they have tested and know they work. Check out these links if you want to avoid the guesswork:

OBD2 Diagnostic Scanner (Basic)

OBD2 Diagnostic Scanner (Advanced)

The Kawasaki diagnostics connector is not a standard OBDII connector so you’ll also need a Kawasaki OBD2 Harness Type 2 to connect the scanner. What isn’t clear from the product listings is whether Woolich include that cable when you buy a scanner. I think not but I’m sure Woolich folks would answer that.

I’m nothing to do with Woolich and haven’t used either of those products – I’m simply putting the information out there for anyone interested. For those not interested - too late, you read it!

A bit more from DUI (Department of Useless Information):

Kawasaki use their own sequence of service codes. It’s my understanding that OBDII scanners will not read those service codes. An OBD scanner will read the standard DTCs (Diagnostic Trouble Codes). The better scanners will also give you a description of the fault but it will be the standard description associated with that error code - not an H2 SX specific code.

For example code P0335 is the standard code for Crankshaft Position Sensor Malfunction. It’s the same code whether you read it from a Ford, a Toyota or a Kawasaki. An OBDII scanner should have no problem reading that – although it’s not going to display the corresponding Kawasaki Service Code 21. Fortunately, the service manual provides a listing of Service Codes and their equivalent DTC. By the way, those DTCs actually have some meaning:

• First character P = Powertrain

• Second character 0 = Standard OBDII code

• Third character 3 = Ignition system or misfire

Where it gets more complicated is when you have a non-standard code. I believe OBDII scanners will read those codes but will display only the code with no description. Then there are some faults for which there is no code. Example: Service Code EFB - Right cornering light malfunction. Pretty easy to understand why an OBD scanner wouldn’t handle that one – although some cars have cornering lights.

There you go, not the most useful information ever posted but may interest someone.

Fault codes can be displayed on the dash. Are there some codes that the H2 SX will show the engine light for but not display in the dash?

Correct. To display service codes scroll through to Odometer display on the dash. Push and hold the Upper Button and Reset Button to start self diagnosis procedure. Any error codes will be displayed on the dash. I don't know if there are any service codes that cannot be displayed - the service manual doesn't list any.

Hey 57x
I had the same experience as you today. Put what I thought was
93 Premium in the tank this morning and got the check engine light and low power mode after accelerating onto the highway here in south Florida. Pulled over, checked what I could and bike restarted with full power. Looked up your posts and studied my Shop Manual. Had the 7B code. Put 6 ounces of octane booster in and did the reset routine on the road, check engine light is off-fault erased. I am just
guessing I may have received 87 octane from the 93 pump at 7/11.
Thanks for yours and others’ posts which helped prepare me to clear the fault.

yeahhhh, I would never buy gas from a convenience store (7/11, AM/PM mini-marts, places like that).
