Fault Code Extraction and Deletion Procedure

Fault Code Extraction and Deletion Procedure

System error information is stored in the Air Conditioning Control Module (A/CCM) up to a maximum of 5 faults. Should a sensor fault occur there will be an audible 'beep' and the message 'Er' will be displayed on the control panel LCD display for some 5 seconds after ignition on. Please note that this will happen only once in any ignition switch cycle. The error source may be accessed by the following procedure.


NOTE: Codes 1-15 and 21 only will cause audible beep and 'Er' display.


- Switch off the ignition.
- Press and hold the 'Auto' and 'Fresh/Recirc.' buttons simultaneously, and switch on the ignition.
- All the control panel LED's and all LCD segments will flash on and off. Any function LED indicator which does not flash on/off suggests a fault condition within that area of the panel, or with the LED.
- Any LCD element which fails to flash on/off indicates a fault within the panel or display element.
- Press 'Auto'.
- Press 'Face' to scroll through a maximum of 5 fault codes.


NOTE: If '0' is displayed, there are no stored fault codes, wait 30 seconds to allow system self-test.


- The control panel display will flash repeatedly indicating a list of two digit numbers.
- If, when a code is displayed, an accompanying 'beep' is emitted, the indicated fault is current and therefore still present within the system. A code displayed without an accompanying 'beep' indicates a fault had previously occurred but is not present within the system.


NOTE: It is advisable to check all areas indicated with cleared fault codes. Such faults may reoccur if intermittent problems are present in the system.


- To delete stored and cleared fault codes simultaneously press 'HRW' and 'FACE' switches.
- After investigating and correcting all stored faults, press the 'Push Off' button to restore normal operation with de fault panel settings, i.e. AUTO at 24 °C.
