מזגן מוציא אויר חם לאחר פירוק והרכבת אלטרנטור

שלום לחכמת הפורום,
ZJ, 5.2, מזגן הפסיק לעבוד בדיוק לאחר הרכבת אלטרנטור.
רעיונות לפני שמתחיל לבדוק?
תודה

תבדוק שלא נגעת באיזה צינור גז בטעות...

נפתרה הבעיה.
ביצעתי ריסט ובדיקה למחשב המיזוג והמזגן התחיל לקרר.
יש תהליך מאד מפורט בספר רכב (למוסך) שבודק כל חיישן וכל מדף ומנוע במערכת המיזוג ומחזיר את כולם למקום.
בקיצור, מוסך רגיל היה מערבב אותי ולא בטוח מוצא את הבעיה.
10 דק בלי לפתוח מכסה מנוע :-)

אצל מי ביצעת את הבדיקה.
נמרוד

בבית :-). רק עם ספר רכב.

תוכל להסביר את התהליך בכללי?

זה בודאי קרה בעקבות ניתוק המצברף לפני החלפת האלטרנטור.
בברכה - רפי לין

רפי צודק. אכן ניתוק המצבר גרם לאיפוס מערכות מסויים.
אשלח בערב את כל הפרק של מיזוג האויר ברכב

SELF-DIAGNOSTIC DISPLAY

In the self-diagnostic mode, the test information is displayed in the vacuum fluorescent display area of the heater-A/C control. The area of the display where the temperature control comfort level is normally dis- played is called the Test Selector. The Test Selector is used to display fault codes, identify the test mode, and show the values of the circuits being tested. The following information describes how the values in the Test Selector display should be interpreted.

(1) The Select Test mode will have only 00 dis- played in the Test Selector, and no stick man will be displayed. This is the self-diagnostic mode from which the various tests may be selected.

(2) If the stick man floor arrow (bottom) is show- ing, the displayed Test Selector value will be a range of numbers below zero (Fig. 13).

Fig. 13 Test Selector Values Below Zero

HEATING AND AIR CONDITIONING

24 - 17

(3) If the stick man appears, but no arrows are showing, the displayed Test Selector value will be a range of numbers between zero and ninety-nine (Fig. 14).

Fig. 14 Test Selector Values Between Zero and Ninety-Nine

(4) If the stick man panel arrow (middle) is show- ing, the displayed Test Selector value will be a range of numbers between 100 and 199 (Fig. 15).

Fig. 15 Test Selector Values Between 100 and 199

(5) If the stick man panel (middle) and defrost (top) arrows are showing, the displayed Test Selector value will be a range of numbers between 200 and 255 (Fig. 16).

(6) At any time during the self-diagnostic tests, you may return to the Select Test mode by turning the rotary temperature control knob one click in either direction. Again, the stick man and arrows are not shown in the Select Test mode. At this point, you have the option of monitoring or testing another cir- cuit (Fig. 17).

DIAGNOSIS AND TESTING (Continued)

FAULT CODE TESTS

Fault codes are two-digit numbers that identify a circuit that is malfunctioning. There are two differ- ent kinds of fault codes.

1. Current Fault Codes - Current means the fault is present right now. There are two types of cur- rent faults: input faults, and system faults.

2. Historical Fault Codes - Historical or stored means that the fault occurred previously, but is not present right now. A majority of historical fault codes are caused by intermittent wire harness or wire har- ness connector problems.

ENTERING THE ATC SELF-DIAGNOSTIC MODE

To enter the ATC self-diagnostic mode, perform the following:

(1) Depress the A/C and Recirc buttons at the same time and hold. Rotate the rotary temperature control knob clockwise one click.

(2) If you continue to hold the A/C and Recirc but- tons depressed, the ATC control module will perform a Segment Test of the vacuum fluorescent display. In the Segment Test you should see all of the display segments illuminate. If a display segment fails to illuminate, the vacuum fluorescent display is faulty and the heater-A/C control must be replaced.

(3) After viewing the Segment Test, release the A/C and Recirc buttons. This will cause the Test Selector to display a “00” value, and no stick man will be displayed. This is the Select Test mode. At this point a number of tests can be selected, however, the Fault Code Test should be performed first.

NOTE: A battery disconnect will erase all faults stored in Read Available Memory (RAM) of the ATC control module. It is recommended that all faults be recorded before they are erased.

RETRIEVING FAULT CODES

(1) To begin the Fault Code Tests you must be in the Select Test mode. With a “00” value displayed in the Test Selector and no stick man, push either the A/C or Recirc button.

(2) The stick man will appear indicating you have entered the Fault Code Tests. The values displayed in the Test Selector will range from “00” to “64.”

(3) Fault codes will appear and repeat if there are more than one. Record all of the fault codes, then see the Current and Historical Fault Code charts for the descriptions. If there are no fault codes, the “00” dis- play value will remain displayed in the Test Selector.

(4) If a Fault Code “25” or “29” is displayed, the ATC control module must be replaced before any fur- ther testing is performed.

(5) For more detailed information about a fault code, see the Input Circuit Tests or the Output Cir- cuit/Actuator Tests.

CLEARING FAULT CODES

Current faults are cleared whenever the problem goes away. To clear a historical fault, depress and hold either the A/C or Recirc button for at least three seconds. The faults have been cleared when two hor- izontal bars appear in the Test Selector display.

אני אשמח לשתף את כל החומר אם מי שרוצה

הרבה מאוד פעמים ניתקתי מצבר, ולא קרה קלום, מעניין למה זה קרה לך.
