Honda Jazz/City CVT Reset Procedures

[drey]

Thanks to CVT!

1. Start the car and run it to operating temp (no other electricals must be used like aircon, radio, power windows, mirrors, lights). Keep the doors closed so that the dome light is not on.
2. Shut down the engine
3. Start engine again and turn on headlights, without operating any other electrical load (other than headlights).
4. From P(ark), shift to N, D, S, L, S, D, N while waiting at least 2 seconds before shifting to the next position
5. Repeat the N, D, S, L, S, D, N sequence for 3 times
6. Turn-off headlights
7. Shutdown engine
8. Drive and investigate if the fuel consumption decreases.

Sorry for the ignorant questions, but what is the purpose of resetting the CVT?

Is this the same procedure, after changing to a new battery?

Yes, bro.

It is encouraged that you have your battery changed at Honda Cars because they need to reprogram your CVT (for those who has this type of transmission in their City or Jazz cars). Trouble is, there, the battery is expensive and you pay for the reprogramming activity.

So with this, you can buy your battery from any of the dealers and reprogram the CVT yourself. A much more cost-effective alternative.

I am just wondering why these car manufacturers did not use non-volatile memories, like flash to store the program values so that you need not program the CVT when you change battery. Well.....

so does this mean that you need to reconfigure your CVT back over again everytime you disconnect your battery? For most repairs, they recommend disconnecting the battery?

That is how I understand it bro. I could be wrong.

Although I disconnected my battery only once when I changed it over half a year ago. Did not try though to drive the car without going through the above procedure to feel/assess if there's a change in the shifting pattern....

*cvt,

sir pa enlighten lang po..

magkaiba po ba yung reprogram ng cvt at calibration ng cvt?

tama po ba yung pag nag palit ka ng battery eh dun lang irereprogram yung cvt at hindi kailangan icalibrate yung cvt?

nalilito lang po talaga ako

salamat po

[CVT]

Yes, that was what I did with my former Jazz CVT.

I replaced the battery and then, I reprogrammed the CVT using the procedure that was shared here....

Calibration, in my opinion, may be required if the car is not performing to your expectations after doing the above. And, you need to have Honda do this for you, unless you have identified shops which can do the same...

Follow up on this cvt reprograming. Is this applicable to honda city VX model 2014 model? Lately i experienced my city cvt transmission unusual shifting since the battery was disconnected. The rpm goes up when decending down heel then when highway cruising sometimes rpm is hunting UP & down causing the engine to rev high. I brought it to honda casa they diagnosed and found no fault , and they are recommending palit ng transmission!!! Need help if any one of you have to recommend on me. Thanks

may problems ba ang cvt transmission ng 1.3 jazz? narinig ko lng kzc...

[BratPAQ]

Yung 2009 city ba cvt pa rin? We just changed the battery and namamatayan ng makina coming from neutral, full stop or a slow down. I hope this reset might help, pero walang L yung gears, hanggang S lang.

gud vning mga sirs, just got my honda jazz 2009 tiptronic, just wondrin kung san ang temperature gauge niya . . hehe parang wala kasi ako makita eh.

Walang temp gauge iyan.

Noticed the blue light in your instrument panel when you first start the car in the morning? That's the temp idiot lamp, telling you that the engine is below its operating temperature.

After running the engine for a while, the light will disappear to tell you that it has reached its optimum operating temperature... This is your normal driving condition.

It will light up (red I think) if your engine is overheating....

OT na tayo rito...

Your ride is 5AT and not CVT

ang pinakamagandang remedyo dito para iwas sa re-set o calibration ng cvt...
- bago tanggalin ang old battery ay dapat ikabit muna yung bagong baterya in parallel connection using jumper cable.
- carefully remove the battery terminals from the old one and ensure jumper cables are not loosen from the new battery
- place the battery terminals into the new battery and tighten back
- remove jumper cables
ganito kasi ang ginawa ng battery shop sa aking 2004 city and no abnormalities noted after the battery change.hth
i've been missing though my classic city's 7-speed cvt tranny coz we parted ways when i needed a higher ground clearance car.

[ecneret]

pareho din yata ng sa city yan sir. pansinin mo sa morning pag-start mo may blue color na temperature icon/logo... mag-a-appear lang ulit yun pag nag-over heat pero in red color na... cmiiw...

Another way to avoid the need to reset is to keep the engine running while replacing the battery, this way the computer board doesn't lose power.

Hi Guys!

Pahelp naman.. I'm planning to buy my 1st car. planning to buy City 08-09. kaso based sa mga thead na nakita ko, may problem daw ang honda sa CVT? for AT transmission? noob question pa-explain naman kung anong problem toh? Automatic is mandatory for me kasi gagamitin din siya ng mom ko especially pag-uuwi ng province. dami nagsasabi na go or M/T City para wala ako pagsisihan.. I can't afford a brand new car sa ngayon. up to 450k max lang ang kaya ko iloan.

mahal ba imaintain ang City 08-09 na AT? hindi ba ako magkakaroon ng sakit sa ulo at bulsa in the long run?

Vios 08-09 ang isa sa pinagiisipan ko.. based on the review.. eto daw pinakalow maintenance at pinakasubok na..
Pero ginagawa kasi siya taxi at common na kaya as much as possible I want to buy City

Help me decide guys! I really want to buy City 08/09 AT.

Pashare naman experience nyo! maraming salamat!

CVT Start Clutch Calibration Procedures
NOTE:
•When any of the following items is applied, the feedback signal memory for the start clutch control in the PCM is cleared. The PCM must be memorized the feedback signal for the start clutch control.
◦Disconnecting the battery terminal(s)

◦Removing the No. 20 ECU (15A) fuse in the under-dash fuse/relay box

◦Replaced the start clutch

◦Replaced the control valve body

◦Overhauled the transmission assembly

◦Replaced the transmission assembly

◦Overhauled the engine assembly

◦Replaced the engine assembly


•There are two methods to calibrate the start clutch control during halts and with driving the vehicle, use one of these methods.

Calibration Procedure During Halts


Special Tools Required
DLC pin box ( 07WAJ-0010100)


1. Apply the parking brake, and block all four wheels securely.

2. Warm up the engine to normal operating temperature (the radiator fan comes on).

3. Make sure that the MIL does not come on and the [D] indicator does not blink.

4. If the MIL comes on or [D] indicator blinks, check the fuel and emissions system or the A/T control system, and recheck after checking.

5. Turn the ignition switch OFF.

6. Connect the special tool (07WAJ-0010100) to the data link connector, then connect the jumper wire between terminals 4 and 9 at the special tool, and turn the switch ON to short-circuit SCS to ground.

7. Press the brake pedal, and continue pressing the pedal unit complete of the calibration.

8. Start the engine under no-load conditions, then turn the headlights on. The headlights must be turned on during calibration.

9. Shift the shift lever into [N] position, and shift to [D], [S], [L] position, then shift back to [S], [D], and into [N] in 20 seconds after the engine is started. The shift lever should stop at each position. Repeat this shifting twice.

10. Check that the [D] indicator comes on for one minute with the shift lever is in [N] position, then the indicator goes off.

11. If the [D] indicator blinks not to come on, or the [D] indicator comes on, and stays on (it does not go off after one minute). Turn the ignition switch OFF, restart the procedures with step 6.

12. Shift to [D] position, and check that the [D] indicator comes on for 2 minutes, then it goes off.

13. If the [D] indicator blinks not to come on, or the [D] indicator comes on, and stays on (it does not go off after one minute). Turn the ignition switch OFF, restart the procedures with step 6.

14. Turn the ignition switch OFF to reach completion.

15. Test-drive the vehicle to verify that a problem does not occur on the start clutch control system.



Calibration Procedure with Driving the Vehicle



1. Warm up the engine to normal operating temperature (the radiator fan comes on).

2. Start the engine under no-load conditions, then turn the headlights on.

3. Start off in [D] position, and drive the vehicle until vehicle speed reaches 60 km/h (37 mph), then decelerate the vehicle in more than 5 seconds without pressing the brake pedal to reach completion.

4. Test-drive the vehicle to verify that a problem does not occur on the start clutch control system.
