Hi guys,

Please someone tell me how to do a Self Learn forDual-zone Climate Control?

Car: Fiat Grande Punto 2008 1.4 8V

Thanks,
jwenn.
 
This procedure is covered in the Grande Punto's eLearn, which you can download from the Forum here.

For convenience I've copied and pasted the information below:


Descriptions > 50 AUXILIARY UNITS > 5040 AIR CONDITIONING CASING A... > 5040 AIR CONDITIONING CASING AND COMPONENTS

SELF-LEARNING PROCEDURE

After the control unit or one of the actuators (excluding the recirculation one) has been replaced, it is necessary to proceed as follows.

CONTROL UNIT REPLACEMENT

Some of the CAN nodes, including the climate control system control unit, are programmed with default settings that the customer will find when they purchase the vehicle. If the control unit is being replaced, the Parts Dept. will send a "virgin" component: once fitted, the data memorized by the Body Computer must be transferred to it by carrying out the PROXI ALIGNMENT procedure using the Examiner.

ACTUATOR REPLACEMENT

The self-learning procedure must be carried out using the Examiner (automatic procedure) or following the instructions given below (manual procedure).

1. Carry out the key on and within 40 seconds press the AUTO and MONO buttons simultaneously and keep them pressed.

2. After a few seconds a figure will appear in the left temperature display and decrease (from 05 to 00) (count down) indicating the remaining time before the start of the procedure (keep the AUTO and MONO BUTTONS PRESSED).

3. When the left temperature reaches the value (00), releasing the auto and mono buttons will initiate the procedure lasting about 40 seconds.

4. Entering into local fault diagnosis, at the end of the procedure, the right temperature may display the following values:

00 = SELF-LEARNING taken place with OK outcome
01 and flashing = SELF-LEARNING taken place with NOK outcome
02 = SELF-LEARNING in progress
03 and flashing = SELF-LEARNING not completed


The self-learning procedure does not take place if the AUTO and MONO buttons are released before the left temperature reaches zero.

The control unit makes the left temperature flash if the self-learning has not been carried out or if the result is not positive.

FORCED EXIT FROM THE PROCEDURE

When in progress, the self-learning procedure may be:

1. Aborted: when the user deactivates the key on signal.

In this case the system exits the procedure in a controlled manner without changing the state of the self-learning information memorized previously in the EEPROM and memorizes the data relating to the "self-learning not carried out" state.

2. Interrupted: when the +Battery starts to fail

If this takes place whilst the data is being stored in the EEPROM, the system does not manage to guarantee this information and the data relating to the "self-learning not carried out" state is memorized.

PROBLEMS DURING THE SELF-LEARNING PROCEDURE

If the procedure cannot be completed properly due to a problem with one or more of the actuators, the system exits the procedure without modifying the data memorized previously in the EEPROM and memorizes the information relating to the "self-learning not carried out" state.

Hope this helps fix your problem!
 
Very nice and complete answer, thanks for the effort of making things understandable to others...

Congrats & BRs, Bernie
