Check it again mate, your code of 88.8 doesn't seem right.

The codes and their meanings.
B2516: Blower module fault
B2308: Interior temperature sensor motor fault
B2298: Footwell temp sensor Short
B2297: Footwell temp sensor open circuit
B2266: Air Temperature control motor
B1676: Voltage incorrect (check charging system)
B1342: Faulty EATC module (clear codes to reset, if fault code re-appears, duff module)
B1263: Faulty Dash/Footwell flap motor
B1262: Faulty defrost (screen) Motor
B1261: Sun load sensor short circuit
B1253: Interior temp sensor short
B1251: Interior temp sensor open circuit
B1242: Recirculated air flap motor fault (IIRC this code sometimes occurs even though there is not a fault)
B1200: Same as B1342, Faulty module.

The codes are displayed in pairs with a 2 second pause.
e.g. B2297 would be shown as: "22" then a 2 second pause, then "97"

Run the diagnostic mode again and see what you get. Before you get too concerned that something is faulty press the Defrost button to clear any codes. This is all I did with mine and everything worked okay afterwards.

Thanks Mike,
something very wrong here i have tried self test three times now and still 88.8 comes up with a/c eco at the side of it. tried defrost button (i assume you mean button at top, quick clear button) fan runs for two / three seconds then stops. but on trying self diagnosis code 88.8 is still in. took it to local main dealer . he wanted £90 to check it plus £90 per hour for repairs.

Dave,

Something very strange there then? Below is the self diagnostic procedure from Ford, so I've no idea where the 88.8 is coming from:

To start self-diagnosis or to read out the fault memory, the ignition key must be turned to the "ON" position and the battery voltage must be between 9 V and 16 V.

Activation of self-diagnosis

On the E(A)TC module, briefly PRESS the "OFF" and "FOOTWELL" buttons simultaneously for at least 2 seconds, then PRESS "AUTO" within 1.5 seconds. The self-diagnosis which then starts lasts a few seconds. An animated display appears in the E(A)TC display during this time. Any faults found are displayed in the form of trouble codes. Example: First of all, "93" flashes for 2 seconds, then "42" flashes for 2 seconds - DTC 9342. If no faults are stored, then all of the segments in the display are actuated. The following table gives information on the possible DTCs and their corresponding meanings. Diagnosis mode can be stopped at any time by PRESSING any button on the E(A)TC module.

Note:
If the "DEFROST" button is pressed to end the diagnosis mode, all DTCs in the fault memory will be deleted.

Be interesting to know of any solution to this one!

thanks mike,

have followed instructions to the letter, but still 88.8 comes up -- could this be showing the temp ???.

well thanks for your help . will plod on and start changing items. have ordered a used digital climate control --will change this and hope.

just as a different question -- do you know the fuse number for the rear cigar lighter on my 2006 mondeo tdci estate-- the haynes manual does not show it.

thanks again mike for your instructions

Hi i think that perhaps 88.8 means no fault as in the statement made on the diagnosis list "If no faults are stored, then all of the segments in the display are actuated"
im just having a guess so cant confirm
Cheers

If the test is complete and reports no errors then all the symbols will be displayed. If a fault is detected, then the relevant error code will be displayed as a flashing number, at which point you refer to the fault code table above.

thanks for this,
but as i have said i have followed the instructions to the letter and still the number 88.8 comes up with auto/eco at the side . it would appear from what you say that it is not recording a fault code.

thanks
