Self-Adjustment Of Damper Motor

Post by Pidde » Sat Jun 29, 2019 3:59 pm

Hi everyone
hope you can read my bad english

Volvo 850 1995

Someone who has an idea why I get error message 5-1-1 all the time at ECC

i have tried 3 different ECC control panels and I have tested all Damper Motor and they work perfectly what i can see and hear i have made Self-Adjustment Of Damper Motor calibration 3 times and after every attempt to make Damper Motor calibration i got error code 5-1-1 does not get any other error messages only 5-1-1,

Someone who has encountered this error and may be able to help me

/Peter

From this link, it would appear that there may be a step or issue coming up prior to doing the calibration and that is that the damper limits have not been set. As to how this is done I don't know.

Thank you for the link I have already read it many times

so it must be one or more damper motor that fails when i do a calibration of damper motor for it cannot be possible for three ECC control panels that can be broken

Is it possible to measure each damper motor without removing them, I mean from the ECC control panel three contacts

Today I have tried to do Self-Adjustment Of Damper Motor calibration but still get the error code 5-1-1 and have tried two different ECC control panels and have tested all the damper motors and they opened and shut as they should so now have I run out of ideas
when i have started the car again and are out driving it wants to perform Self-Adjustment Of Damper Motor calibration though i have not activated test mode 4 and A / C control panel blinks
grateful for several tips

Peter

One basic question (forgive me if this sounds stupid)... what symptoms or problems are you experiencing with the climate control system in addition to the 5-1-1 code?

One helpful description of how to carry out the initialization procedure is available here:
viewtopic.php?t=27298

First:
Ignition off.
Blower switch in Manual position, half power.
Recirculation on.
Left and right temperature controls set to 22°C or 72°F.
Air flow selector set between Ventilation/Defrost. (exactly between face vent and defrost, the selector is pointing approximately 335 degrees, if defrost is 0 degrees and the direction of rotation is CW)
Air conditioning (A/C) switch on AUTO.

Then:
Ignition on.
Activate DTM 4 for self-adjustment of damper limit positions.
Wait approx. 10 seconds to let heater fan start.
Ignition off to exit test mode 4.
Ignition on.

Finally:
Drive car for a few minutes at a speed over 30 km/h. The control unit will then carry out self-adjustment while driving. (Editor's Note: you should be able to feel this happening, if you don't, it isn't happening!)
Stop car but leave ignition on for at least two minutes to enable control unit to store all values.
-----------

There is also some potentially helpful advice on alternative tools and methods to try here:

1997 855 GLT (Light Pressure Turbo) still going strong. Previous: 1986 240 GL rusted out in '06, 1985 Saab 900T rusted out in '95, 1975 Saab 99 rusted out in '95, 1973 Saab 99 rusted out in '94

What happens is when I turn the ignition to position 2 then REC / AC starts flashing and when I drive with the car after a little while I can hear how Damper Motor tries to do what I think a Damper Motor calibration (then what i think it goes into safe mode and works) then when I turn off the ignition to position 2 it flashes again.

how to do an ECC RESET PROCEDURE.

I have done exat a calibration like this

First:
Ignition off.
Blower switch in manual position, half power.
Recirculation on.
Left and right temperature controls set to 22 ° C or 72 ° F.
Air flow selector set between Ventilation / Defrost. (Exactly between face vent and defrost, the selector is pointing approximately 335 degrees, if defrost is 0 degrees and the direction of rotation is CW)
Air conditioning (A / C) switch on AUTO.

then:
Ignition on.
Activate DTM 4 for self-adjustment of damper limit positions.
Wait approx. 10 seconds to light heater fan start.
Ignition off to exit test mode 4.
Ignition on.

Finally:
Drive a car for a few minutes at a speed above 30 km / h. The control unit will then carry out self-adjustment while driving. (Editor's Note: you should be able to feel this happening, if you don't, it's not happening!)
Stop car but leave ignition at at least two minutes to enable control unit to store all values.
