I recently bought a 2002 XJ8 Sport in Oklahoma City when it was about 85 degrees out. The A/C was nice and cold so I figured the climate control system was working good. When I got home (Wisconsin) and wanted to turn up the temperature it still blasts out cold air- no heat whatsoever. I believe the control panel is functioning/communicating with the A/CCM properly.I can vary the fan speed which indicates communication from the control panel-> A/CCM is OK (A/CCM outputs controlfan speed) and, the outside temperature display is accurate indicating communication from the A/CCM -> control panel is OK (ouside temperature probe is an A/CMM input). I can feel the heater core circulatingpump (12VDC) running but have not removed it to check flow. I can also hear the heater coolant flow valve click on/off but, again, have not removed it to check flow.I stopped at a local ADVANCE AUTO store to borrow a scanner and no DTC's showed up but I don't know (and neither did thestore guy) if the scanner would pick up B-codes (Body- climate control) or U-codes (A/CCM serial communication errors). Anybody have any ideas?? Does anybody knowof a software/interface unit for a PC or PDA that can access ALL of the Jaguar DTC's??

It is very important to positively identify the area of concern before starting a rectification procedure. A little time spent with your customer to identify the conditions under which a problem occurs will be beneficial. See below for example:
No defrost document.write(languageText("posssources")); Possible Source(s): [*]No airflow to windshield
document.write(languageText("actionstake")); Action(s) to take:
[ul][*]Check blowers and flaps [/ul] document.write(languageText("posssources")); Possible Source(s): [*]No function in defrost mode
document.write(languageText("actionstake")); Action(s) to take:
[ul][*]Check A/CCM [/ul] document.write(languageText("posssources")); Possible Source(s): [*]Mode selection not available

[ul][*]Check control panel communication [/ul] document.write(languageText("posssources")); Possible Source(s): [*]Airflow OK but no heat
document.write(languageText("actionstake")); Action(s) to take:
[ul][*]Check water pump and valve [/ul]Relevant criteria are: Weather conditions, ambient temperature, intermittent or continuous fault, airflow fault, temperature control fault, distribution fault and air inlet problem.
Functional Check newStep(0); This simple 'first line check' will allow you to ascertain whether the system is operating within its design parameters, without recourse to PDU.
stepNum(0); 1 . With the engine at normal running temperature.
stepNum(0); 2 . Presss AUTO to display selected temperature and illuminate AUTO and A/C state lamps.
stepNum(0); 3 . Rotate FAN to increase or decrease lower speed, verify bar graph representation.
stepNum(0); 4 . Select A/C to toggle on or off. (The compressor may be inhibited by the ECM should either the engine temperature NOT be normal or the ambient be < 2° C).
stepNum(0); 5 . Select RECIRC , state lamp should be lit and the recirculation flaps open.
stepNum(0); 6 . Select distribution buttons in turn, verify correct air distribution and relevant state lamp.
stepNum(0); 7 . Select DEFROST , check max fans and air to the windshield.
stepNum(0); 8 . Cycle TEMPERATURE to ' HI ' and ' LO ' to verify demanded variations and display operation. Note that extremes will provide max heat or cold independent of in-car temperature.
stepNum(0); 9 . Select EXT to toggle between ambient and control temperatures.
stepNum(0); 10 . Select F (where fitted) and R - noting exterior mirror; verify timer and operation (glass may be warm to the touch)

System Self-test newStep(0); Control Panel Interrogation Procedure newStep(0); The control panel has a self-diagnosis feature, and is capable of displaying and clearing stored fault codes.
Climate control is an integrated system, therefore it is recommended that the PDU is used for fault diagnosis. The fault codes displayed with the control panel self-diagnosis feature are not as comprehensive as those of the PDU. The PDU will display the relevant fault code, fault code description and information of the system peripherals at the time the fault occurred.
Fault Code Extraction and Deletion Procedure newStep(0); 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 and RECIRC - Switch ignition to ON Display element check #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 and R Clear stored fault codes (may need to be repeated for each fault) #5 Press RECIRC (Press FAN to skip actuator check) Initiate actuator check (Actuator codes 20 through 27 * ) #6 Press FAN Exit error check mode
document.write(languageText("note")); NOTE:
* Actuator codes do NOT equate to system fault codes.
document.write(languageText("note")); NOTE:
Only codes 11, 15 and 21 (see Fault Code Listing) will cause audible beep and 'Er' display.
document.write(languageText("note")); NOTE:
If '0' is displayed, there are no stored fault codes, wait 30 seconds to allow system self-test.
[ul][*]The control panel display will flash repeatedly indicating a list of two digit numbers (see table for code analysis).[*]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. [/ul] document.write(languageText("note")); 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.
