Engine management General information 0 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. 0 Trouble codes are displayed by the malfunction indicator lamp (MIL). The ECM fault memory can also be checked using diagnostic equipment connected to the data link connector (DLC). Accessing Ensure ignition switched OFF. Bridge data link connector (DLC) terminals 6 and earth O. NOTE: Models without a terminal in position 6 of the 16-pin DLC do not display trouble codes using the MIL. Switch ignition ON. Trouble codes will be displayed after a short flash [A] and a long pause rn [B]. Count MIL flashes. Note trouble codes. Compare with trouble code table. Each trouble code consists of two groups of one or more flashes. The first group of flashes indicate the 'tens' of the trouble code [C]. The second group of flashes indicate the 'units' of the trouble code rn [Dl. A short pause separates each trouble code group rn [E]. A long pause separates each trouble code rn [Fl. For example: Trouble code 12 displayed rn. Each trouble code including 12 displayed three times. Year: 1994-00 I Engine code: 25DT, X25DT System: Bosch EDClMSA 11 Erasing The engine control module (ECM) fault memory can only be erased using diagnostic equipment connected to the data link connector (DLC). Repeat checking procedure to ensure no data remains in ECM fault memory.
