PEUGEOT Model: 806 1,9D TurboYear: 1995-00I Engine managementEngine code:System:DHXBosch AS3General informationo Refer to the front of this manual for general test conditions,terminology, detailed descriptions of wiring faults and ageneral trouble shooter for electrical and mechanical faults.Trouble codes are displayed by the malfunction indicatorlamp (MIL) or LED.The ECM fault memory can also be checked and erasedusing diagnostic equipment connected to the data linkconnector (DLC).o Vehicles fitted with a coded keypad: When switching onignition or entering start code ensure diagnostic equipment isdisconnected from the data link connector (DLC).AccessingSwitch ignition ON.Check that MIL illuminates.Connect LED test lamp between data link connector (DLC)terminal C3 and battery positive m.Bridge data link connector (DLC) terminal C2 and earth witha switched lead - contacts normally open m.Operate switch for 2,545 seconds.LED or MIL will now flash trouble code 12.Each trouble code consists of two groups of one or moreflashes O.Long flashes indicate the 'tens' of the trouble code rn [A].Short flashes indicate the 'units' of the trouble code rn [C].A short pause separates each flash rn [B].A long pause separates each trouble code rn [Dl.For example: Trouble code 12 displayed rn.Repeat operation. Note trouble codes.Compare with trouble code table. Rectify faults asnecessary.
