I don't notice this with my auto temp truck..
No, on a properly functioning system you should never hit the high pressure limit. What you experienced was just the low pressure switch. Temperature and pressure are directly related so the colder the system gets the lower the psi and temperature. If for example your system had a 16psi switch, The compressor would kick off when the system dropped to 16psi. Your high side would have say 200psi. When the compressor kicks off the two sides start to balance, the low side rises and the high side lowers. When the low side gets back above say 18-20psi the low pressure switch circuit closes again and the compressor resumes operation.

Default Forscan Administrator

Does anyone know how to get a hold of an administrator for the forscan forum? I applied a few days ago and have not yet received an activation email and the site will not let me contact them since my account has not been activated.


Thanks,


Vic

Default 8" bezel issues

I am in the process of upgrading from a 4.2" to 8" screen with Sync 3 v2.2.
I am unable to get the controls on the bezel to function. Consequently, I have no HVAC control or Media control. I can control the media from the steering wheel, but I am unable to turn it on or off. The HVAC populates on the display, but no information or control is available. I used the as builts from the VIN that was associated with the bezel originally. I am reading through all of the threads, but have not yet found an answer. Any help would be appreciated.

Even with the correct data you may need to just do something as simple as initialize the module, so try a module reset under the wrench icon in ForScan for your FCIM and APIM.

If more in depth troubleshooting is required I'm sure any of us can lend you some as built examples which are close, but you will have to fine tune each parameter to match your truck.

Here is what the climate screen looks like.


I don't show an FCIM module, could that be part of the issue?

I performed a reset on the APIM, but no luck. Thanks for the assistance, I don't know how much fun it would be to ride around with no AC. I know it is something simple. I do this for a living (computer programming), I'm just new to forscan. (1st day)

Firerunner,
Can you send me your settings for this? I am still unable to get my HVAC and media buttons to work.
Thanks,

Sorry C1PHER, My setting won't do you any good 'cause I'm still using SYNC 2
