I 1 9- , ROVER Model: 2001CoupelCabrio 1,6 400TTourer 1,6 I Engine rnanagernentltransrnission I NOTE: Engine control module (ECM) incorporates transmission control function. 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. Trouble codes are displayed by the LED incorporated in the engine control module (ECM). 0 Switch ignition ON. If MIL illuminates to indicate a fault but no trouble codes are stored, suspect DLCIMIL wiring, MIL or ECM. 0 The ECM fault memory can also be checked using diagnostic equipment connected to the diagnostic socket Accessing Switch ignition ON. DO NOT start engine. Count ECM LED flashes m. Note trouble codes. Compare with trouble code table. NOTE: No trouble codes stored if MIL illuminates continuously. Trouble codes 1-9 are indicated as follows: E Individual short flashes display trouble code [A]. A short pause separates each flash rn [B]. A long pause separates each trouble code [C]. For example: Trouble code 3 displayed rn. Trouble codes greater than 9 are indicated as follows: o Long flashes indicate the 'tens' of the trouble code El [A]. n Short flashes indicate the 'units' of the trouble code [C]. 0 A short pause separates each flash [B]. A long pause separates each trouble code El [Dl. For example: Trouble code 14 displayed El. c A B A B A C A B A B A
