[cypriotxx]

Hi There

i bought stolen and recovered NC750 integra 2015 on auction ,
there was no key set on it and the ecu with battery was stolen , i have bought new key set complete and new ECU ,
when i turn on the ignition i am having HISS light showing and no noise from the rest of the parts like starter relay or starter motor , ? what can i do please ? all fuses are seem to be ok...

Thank you so much for your time and kind help. any advice really appreciated ..

You should go to Honda authorized dealer.
If you think you're able to fix it by yourself, firstly you need Service Manual specific for your NC Integra.

I cannot guarantee that this would work, but, based on older Service Manual, when you replacing ECM/PCM you need to do:

(from 2012 NC700 Service Manual)

If the ECM/PCM is replaced, perform the following:
– Key Registration Procedure (page 23-6)
– Clutch Initialize Learning Procedure (NC700XD/
SD) (page 12-120)

page 23-6:

(This is only small part. There is 14 pages more in Immobilizer System (HISS) service section.)

When the ECM/PCM is faulty:
1. Obtain a new ECM/PCM and two new transponder keys.
2. Grind the keys in accordance with the shape of the original key (or use the key number plate when all key have been lost).
3. Replace the ECM/PCM with a new one (page 4-67).
4. Turn the ignition switch ON with a first new key and engine stop switch " ". The HISS indicator comes on for two seconds, then
it blinks four times repeatedly.
• The first key is registered in the ECM/PCM.
• If there is any problem in the registration, the system will enter the diagnostic mode and the indicator will remain for approx. ten
seconds, then it will indicate the diagnostic code (page 23-7).
5. Turn the ignition switch OFF and remove the first key.
6. Turn the ignition switch ON with a second new key. The HISS indicator comes on for two seconds, then it blinks four times
repeatedly.
• The second key is registered in the ECM/PCM.
• If there is any problem in the registration, the system will enter the diagnostic mode and the indicator will remain for approx. ten
seconds, then it will indicate the diagnostic code (page 23-7).
7. Turn the ignition switch OFF and remove the second key.
• The system (ECM/PCM) will not enter the normal mode unless the two keys are registered in ECM/PCM.
• The third new key cannot be continuously registered. When it is necessary to register the third key, follow the procedures "When
the key has been lost, or additional key is required" (page 23-3).
8. Check that the engine can be started using all registered keys


page 12-120

CLUTCH INITIALIZE LEARNING (PCM)
• If the PCM and/or clutch assembly are replaced,
perform this procedure.
• Before starting this procedure, check the following:
– PGM-FI system and DCT system have no DTC.
– Engine idle speed is normal.
– Transmission is in neutral and cooling fan stops.
• Do not operate the throttle during clutch initialize
learning
1. Warm up the engine to the normal operating
temperature (engine oil temperature: 50 – 110°C/
122 – 230°F) and stop it.
If the PCM is replaced with a new one, the "D" and "S"
indicators [1] come on to indicate that the clutch
initialize learning is necessary when the ignition switch
is turned ON. Further the large "L" [2] (extremely low oil
temperature) or small "L" [3] (low oil temperature) is
displayed on the shift indicator to indicate that the
engine warming up is necessary if it is not warmed.
2. Turn the ignition switch ON with the engine stop
switch " " while pushing the D switch [1] of the N-D
shift switch. The MIL [2] will come on.
Release the D switch after the MIL goes off.
• When only the dual clutch assembly is replaced:
No indication appears on the shift indicator [3].
• When the PCM is replaced:
The "D" and "S" indicators [4] come on.
3. Operate the N-D shift switch [1] in the sequence as
follows:
– Push the D switch
– Push the D switch
– Push the N switch
– Push the D switch
– Push the N switch
• When only the dual clutch assembly is replaced:
The PCM is ready to clutch initialize learning when
the "D" and "S" indicators [2] lights, and the "–" [3] is
displayed on the shift indicator and blinks at interval
of 2 seconds.
• When the PCM is replaced:
The PCM is ready to clutch initialize learning when
the "–" is displayed on the shift indicator and blinks
at interval of 2 seconds.
When the engine is not warmed up enough, the large
"L" [4] (extremely low oil temperature) or small "L" [5]
(low oil temperature) is displayed on the shift indicator.
If so, warm up it until the "L" on the shift indicator goes
off. Stop the engine and perform the steps 2 and 3
again.
4. Start the engine and let it idle. The "–" [1] on the shift
indicator starts blinking at interval of 2 seconds. The
Clutch Initialize Learning is successful, when the "–",
"D" and "S" indicators [2] go off.
Stop the engine.
The clutch initialize learning is unsuccessful, if the "–"
starts blinking at interval of 0.5 second or it goes off,
and the "D" and "S" indicators stay on. Perform the
initialize learning procedure from step 2 again.
5. Stop the engine.
6. Restart the engine, push the D switch of the N-D
shift switch and check that the "D" indicator comes
on.

ABS light is staying on and it wont go into upper gears ?

any ideas where to start with this two symptoms ?

Thank you so much for your support

 

[cypriotxx]

Without Service Manual you won't go too far.
Just from top of my head:
Do you have correct PCM?
Do you know how to read DTC (Diagnostic Trouble Code) for DCT and ABS and PCM.
If there is a trouble code, appropriate indicators would blink in specific intervals. For PCM it's MIL (Malfunction Indicator Lamp - check engine lamp). For DCT it's a shift indicator and for ABS - ABS indicator.

"It won't go into upper gear" - In both modes "D" and "S", or only in "S"? If only in "S" mode that maybe normal. With moderate acceleration you need to reach speed about 95-100 km/h and stay at this speed for a moment. DCT should shift to 6th gear. Does manual mode work?

ABS requires specific troubleshooting for your type of NC.

(I tried to upload some jpg examples from my 2015 CTX700ND – (not Combined ABS) Service Manual, but “Insert Image function” doesn’t work here at this moment. Something for Administrator.)

So, in text form only:

ABS INDICATOR STAYS ON (Indicator does not go off when the motorcycle is running, but DTC is not stored)

1. Service Check Line Short Circuit Inspection
Turn the ignition switch OFF.
Disconnect the ABS modulator 18P (Black) connector.
Check for continuity between the wire harness side ABS modulator 18P (Black) connector 14 terminal and ground.
TOOL:
Test probe 07ZAJ-RDJA 110
CONNECTION: 14 - Ground
Is there continuity?
YES - Short circuit in the Brown wire
NO - GO TO STEP 2.

2. Indicator Signal Line Open Circuit Inspection Short the wire harness side ABS modulator 18P
(Black) connector 13 terminal to the ground with a jumper wire.
TOOL:
Test probe 07ZAJ-RDJA 110
CONNECTION: 13 - Ground
Turn the ignition switch ON and engine stop switch
"run".
Check the ABS indicator.
Does it go off?
YES - GO TO STEP 3.
NO - • Open circuit in the Orange/black wire
• Faulty combination meter (if the Orange/black wire is OK)

3. Modulator Ground Line Open Circuit Inspection
Turn the ignition switch OFF.
Check for continuity between the wire harness side
ABS modulator 18P (Black) connector 9 terminal
and ground.
CONNECTION: 9 - Ground
Is there continuity?
YES - GO TO STEP 4.
NO - Open circuit in the Green/yellow wire

4. Fuse Inspection
Remove the fuse box cover and check the ABS
MAIN fuse (7.5 A) [1] in the fuse box for blown.
Is the fuse blown?
YES - GO TO STEP 5.
NO - GO TO STEP 6.

5. Power Input Line Short Circuit Inspection
With the ABS MAIN fuse (7.5 A) removed, check for
continuity between the wire harness side ABS modulator 18P (Black) connector 7 and ground.
TOOL:
Test probe 07ZAJ-RDJA110
CONNECTION: 7- Ground
Is there continuity?
YES - Short circuit in Red/black wire
NO - Intermittent failure. Replace the ABS MAIN
fuse (7.5 A) with a new one, and recheck.

6. Power Input Line Open Circuit Inspection
Install the ABS MAIN fuse (7.5 A).
Turn the ignition switch ON.
Measure the voltage between the wire harness side
ABS modulator 18P (Black) connector 7 terminal
and ground.
TOOL:
Test probe 07ZAJ-RDJA 110
CONNECTION: 7 (+) - Ground (-)
Is there battery voltage?
YES - Faulty ABS modulator
NO - Open circuit in Red/black wire

thank you so much for your reply

only the abs light is staying on so there is no other error
at the moment i click on N and D buttons only two is working and in D only going as far as the 1st gear goes tried other buttons but not making much difference , i have read somewhere abs light might go off as if i start riding but thats not possible now without seats and all so will try to get the seats first to see if i can give it a little try on the side roads or something ...

The bike needs to know the speed of the wheels for both the ABS function, and for the DCT shifting. I thought I heard that the transmission won't shift to second gear if the front wheel speed is not sensed. You may want to check the integrity of the front wheel ring and sensor.

From NC Integra (2012) User Manual:

"ABS (Anti-lock Brake System) indicator
Comes on when the ignition switch is turned on.
Goes off when your speed reaches approximately
10 km/h (6 mph)."

"ABS (Anti-lock Brake System)
Indicator
If the indicator operates in one of the
following ways, you may have a serious
problem with the brake system. Reduce your
speed and have your motorcycle inspected by
your dealer as soon as possible.
● Indicator comes on or starts flashing while
riding.
● Indicator does not come on when the
ignition switch is in the ON position.
● Indicator does not go off at speeds above
10 km/h (6 mph).
If the ABS indicator stays on, your brakes will
continue to work as a conventional system,
but without the anti-locking function.
The ABS indicator may flash if you turn the
rear wheel while your motorcycle is lifted off
the ground. In this case, turn the ignition
switch off and then on again. The ABS
indicator will go off after your speed reaches
30 km/h (19 mph)."

I misread you thinking that you couldn't reach 6th gear.
Looks like you are on a right track.
670cc is correct. Both wheels have to move.
Good luck.

 

[cypriotxx]

Thank you everyone ,
it is 750cc the model is NC750DE integra sport automatic

once i located missing parts seats ,tail light assembly ,luggage assembly and all in between will start putting all together , i asked dealer how much would it cost and it is really expensive , watching on ebay thats where i found the petrol tank for £30 instead £450(dealer priced)

Hi Lootzyan,
You are referring to and quoting from the service manual.
I’ve been trying to find one, but without any luck.
Could you advise me where to look for it?
Or, should you possess a digital version, send me a copy?
Cheers,
Guzruud

 

[lootzyan]

...Could you advise me where to look for it?
Or, should you possess a digital version, send me a copy?...

The file is relatively large, almost 20MB, so I couldn't send it to you. I don't use a shared cloud service.
This is the official digital copy of the service manual and is for the first non-US models, 2011 NC700. I suppose it was legally available probably in Asia before regional printed copies came out.
It is important to know that this copy has errors in the description of inspection and adjustment of the valve clearance.
A copy is still available for download at - https://www.manualslib.com/manual/1106110/Honda-Nc700xa.html#manual.
The errors are on page 3-11.
