I Engine management Model: Maverick 2,7 D Turbo Year: 1996-98 Engine code: TD27E System: EDC General information Refer to the front of this manual for general test conditions, terminology, detailed descriptions of wiring faults and a general trouble shooter for electrical and mechanical faults. Trouble codes are displayed by the malfunction indicator lamp (MIL). The ECM fault memory can also be checked and erased using diagnostic equipment connected to the data link connector (DLC). Accessing Ensure ignition switched OFF. Switch ignition ON. Bridge data link connector (DLC) terminals IGN and CHK m. Wait 2 seconds minimum. Disconnect bridge wire from data link connector (DLC). Count MIL flashes. Compare with trouble code table. Each trouble code consists of two groups of flashes H. Long flashes indicate the 'tens' rn [A]. Short flashes indicate the 'units' rn [C]. A short pause separates each flash [B]. A long pause separates each trouble code [Dl. For example: 1 long flash followed by 2 short flashes indicates trouble code 12 - mass air flow (MAF) sensor. Switch ignition OFF. CHK IGN

Engine management Erasing Ensure ignition switched OFF. Switch ignition ON. Bridge data link connector (DLC) terminals IGN and CHK O. Wait 2 seconds minimum. Disconnect bridge wire from data link connector (DLC). Bridge data link connector (DLC) terminals IGN and CHK e. Wait 2 seconds minimum. Disconnect bridge wire from data link connector (DLC). Switch ignition OFF. NOTE: Trouble codes can also be erased by disconnecting battery earth lead for 24 hours. WARNING: Disconnecting the battery may erase memory from electronic units (e.g. radio, clock).
