Fault Code Extraction and Deletion Procedure

Fault Code Extraction and Deletion Procedure

Error information is stored in the 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 display for 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

This procedure must be completed through one complete cycle, 1 through 6

Step Result
#1 Simultaneously hold AUTO & RECIRC- Display element check
Switch ignition to ON

#2 Press AUTO Display of stored fault (NUMERIC) code. If ZERO appears, there are no stored codes

#3 Press FACE Scroll through stored faults (maximum of 5)

#4 Simultaneously press FACE & R Clear stored fault codes (may need to be repeated for each fault)

#5 Press RECIRC Initiate actuator check
(Press FAN to skip actuator check) (Actuator codes 20 through 27*)

#6 Press FAN Exit error check mode


NOTE:
* Actuator codes do NOT equate to system fault codes.


NOTE: Only codes 11, 15 & 21 will cause audible beep and 'Er' display.


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.

Should a code be displayed accompanied by an audible beep, the 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 re-occur if intermittent problems are present in the system.

To delete stored and cleared fault codes press 'R' and 'FACE' buttons simultaneously.

After investigating and correcting all stored faults, press the 'Push Off' button to restore normal operation with default panel settings, ie AUTO at 24° C.
