2007 ESP calibration procedure

[Dimon]

Hi everybody!

I have read in many posts that you should do the following procedure to recalibrate the ESP when you have reconnected the battery:

ELECTRONIC STABILITY PROGRAM (ESP)
If the vehicle is equipped with ESP, once the battery is reconnected, the Steering Angle Sensor (SAS) needs to be
calibrated. The SAS requires calibration anytime the battery or an ABS (ESP) component has been disconnected for
any length of time. To calibrate, perform the following:
1. Start the engine.
2. Center the steering wheel.
3. Turn the steering wheel all the way to the left until the internal stop in the steering gear is met, then turn the
wheel all the way to the right until the opposite internal stop in the steering gear is met.
4. Center the steering wheel.
5. Stop the engine.But I have bought Haynes Repair Manual on eBay and it is said the following in this book:

the following (above in my message) procedure does not apply to 2007 models, on which the SAS must be recalibrated with a factory scan tool. If the SAS is not recalibrated immediately after reconnecting the battery or reconnecting an ABS component, the ESP/SAS indicator lamp will flash continuously until the SAS is recalibrated, though it won't set any Diagnostic Trouble Codes (DTCs).Please be as kind as to tell me if this information is correct, or not? If it is, then I'll only have to visit my dealer to recalibrate ESP and SAS.

Thanks in advance.

Well, is your indicator flashing? Seems silly that they would remove the self-calibrating feature. Haynes isn't always that thorough, or correct. Chilton seems to have the best manuals (next to the factory manuals). Anyway, hopefully one of our techs can chime in :-)

No, thanks God, it isn't.

I agree with you. I just wanted to know this for sure, because this is your safety.

Thanks for the information.

Well I would be very grateful to any of them!

Thanks, I am really happy to hear that! :beerchug:

throw that haines manual away,here in the UK we call the haines "THE BOOK OF LIES",If you repair your car to this manual you will be taking things of your car that dont need removing,its crap

this is the correct procedure



What ill effects happen if you don't do this everytime you reconnect the battery?

What ill effects happen if you don't do this everytime you reconnect the battery? the ESP/BAS warning lamp may illuminate until the SAS (steering angle sensor) is initialized.

Good to know fnkychkn!!!

[Redfox0099]

Could me not recalibrating this cause my ESP off, ABS, and ESP/BAS light to come on and go off randomly and U1418 code to be seen when doing the "key dance"????

not likely. U1418 is a loss of wheel speed message.

[Redfox0099]

I replaced the speed sensor so I guess I am screwed since the error message is still there.

2007 Factory service manual states to use star scan after battery disconnect. 2005/6 states to use center sterring wheel procdure.Oringinal question ,can center the sterring wheel work on 2007?.What changed?Has any one tried it on a2007 after a battery disconnect and cleared ESP light.

has this DTC been properly diagnosed or was a sensor just thrown at it in hopes it would fix it?

nothing has changed but the service manual. the original procedure still works.

ESP/BAS Comes on some time and then turns off it also sets a chime. what should i do or is there something wrong with my magnum?

[netnathan]

jees...
Why was this never mentioned before in all these forums? Just discovered?
All the times I disconnected my battery and this was never done.
Does this mean I should disconnect and re-connect my battery and do this?

i wouldn't worry too much about it. it recalibrates when going lock to lock as in parking lot maneuvres.

I have reconnected the battery for many times and the indicator didn't turn on. But today I had to reconnect the battery and all three indicators ESP, BAS and ABS turned on. And you know I was very disappointed when the procedure with turning the wheel did nothing with it! I tried it a lot of times but the all three lights are still on! I think there is no way except of visiting my dealer unfortunately.

I have visited my dealer today.
First sad news. They have find out that my driver's mirror engine is not functioning through the Starscan. That is the reason why I have tried to reconnect the battery yesterday. Thought it might make it work again. So they have ordered a new driver's side mirror for my car.
Second, as for the ESP calibration. We have saw that ESP does not proceed with the calibration because of the absence of tire pressure sensors. Starscan says something like "ESP error, tire pressure sensors failure". Don't remember exactly. So I have already ordered tire pressure sensors at my dealer and they would be next Thursday. We'll see what they are able to do next when sensors are already installed.
The only one reason to be happy today is Auto Headlights with Wipers feature was enabled through Starscan and it works even though this feature had not appeared in the EVIC! Does anybody know if it should?

[fnkychkn]

assuming this is a Euro spec LX???
on north american spec LXs, the TPM (tire pressure monitor) does not cause ESP/BAS or ABS warning lamps to illuminate.

And so doesn't mine also (was driving for few months). Later it was caused by reconnecting the battery. But now I'm unable to calibrate ESP because of their absence (saw this message myself in Starscan).

[fnkychkn]

you have aftermarket wheels with no sensors?
i've worked on plenty of LXs with missing TPM sensors and i'm sure i've had to disconnect the battery. don't remember ever having trouble recalibrating SAS (steering angle sensor). must be a Euro thing. good luck and let us know how it works out.

Thank you very much for the information! I'll let you know when they'll install TPMS sensors.

[Dimon]

You know the funny thing is that I have reconnected the battery for many times but the system had never indicated the need of calibrating the ESP. Once I had even reconnected the battery with no TPMS senors in my wheels and still there was no need to calibrate ESP. But unfortunately the very last time when I was going to connect the battery I put the cable about two or three times accidentally (causing sparkles every time) instead of putting it on from the very first time. I suppose this is the reason why the ESP system was refreshed or reloaded and now it needs to be calibrated.

You were right! Installing TPMS sensors didn't solve the problem. The problem was resolved only when they reseted all settings to their defaults through the Starscan and have reentered the VIN code. They have told me that probably my car recognized some pressure sensor of the ESP which is used only on 5.7 Hemi engines but couldn't find it because mine 2.7 doesn't have it. But I think it is more funny then truth.

I addition the code that Starscan showed was given to Chrysler and it's description was that my car have lost it's configuration. Something like that. Very bad code as they told me. Anyway I'm glad it's in the past.
