Climate Control Self Diagnosis Guide - Mondeo Mk3
Instructions
Activation of self-diagnosis
With the ignition switched on to position 2, on the E(A)TC module, PRESS the "OFF" and "FOOTWELL" buttons simultaneously very briefly, 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.
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!
