G'day all,
Not sure where to post this question.
Which would be the appropriate forum to post a question regarding calibrating the heater blend door in my 1996 NL Ford Fairlane Ghia?
What's the button pushing sequence to enter self test and calibrate mode?

Id be happy if it was either in the Electrical or Interior forum. We can continue in this thread.

information is in technical documents this forum under - Falcon/Fairmont/Fairlane - E-Series - Climate Control Diagnostics complements of - Matti on 30 2002>, Copyright © 2005 Matti, all rights reserved.

note that diagnostic mode is relevant section if only resetting calibration !!!! and testing for faults



Initiating Diagnostic Mode
Ensure that the engine is warm (At least 45*C) Coolant temperature
Turn the ignition switch to the "ON" Position.
For EA-ED Models, Press the "Floor" and "Off" Buttons Simultaneously and Release. After which, all the Climate Control Panel LED's should Illuminate.
For EF/EL/AU Models, Press the "MODE" and the "OFF" Buttons on the climate control module simultaneously and then release.
The control will display 88.8* during the time required for the self-test to be completed.
When the self-test is complete, and the system checks are OK the display will read "OFF". If the system has a fault the display will read "E" and a number from 1 to 8. In the event that multiple errors have been recorded, they can be viewed by pressing the "AUTO" Button.
rectify the problem and clear the fault from the controller memory by initiating the self-test mode twice.
The self-test can be initiated at any time with the resulting error codes being displayed. Normal operation of the system stops when the self-test is activated. To exit self-test and restart the system, push the "AUTO" button. Self-test should be deactivated before shutting the system off. Refer to the Error Code Key in Table 1 for an explanation of error codes





Diagnostic Error Codes (EA-ED-EF-EL-AU Models Only)
ERROR CODE DESCRIPTION CONDITION DETECTED DEFAULT VALUE COMMENT
E1 Electronic Control Unit Faulty Electronic Control Unit RAM air to screen Replace unit
E2 Blend Door Servo Motor Movement of Blend Door out of Range Poor Temperature Modulation Check if motor is disconnected, door movement obstructed, or incorrect wiring
E3 Cabin Sensor Open Circuit Set point directly controls thermal control valve Check for disconnected cabin sensor
E4 Solar Sensor Short Circuit No sun load compensation Check for short in wiring or sensor
E5 Ambient Sensor Open Circuit Assumes abient is 20*C Check for disconnected sensor
E6 Evaporator Temperature Sensor Open circuit between sensor and EEC V Module A/C Clutch does not engage Check for disconnected sensor
E7 Engine Temperature sensor Short Circuit between sensor and EEC V Module Assumes hot engine, I.E. 93*C Check for short in wiring or sensor
E8 (EF/EL/AU Only) - EEC V Communication Line Fault Faulty Line All values from EEC V set at default value of 1*C Check EEC V communication line to ACC


The system reverts to 22*C after completing the self test.

Thanks Moderator and TedW,

I have done the self test / calibrate on my Fairlane-Ghia and the climate control system seems to be working fine.
Thankfully none of the mechanisms were faulty.
Big expensive job avoided. Good result.
I will spread the word.
