the engine management light came on today on my lads fiesta [2000, 1.25] and started flashing,it turned out to be the coil pack so i fitted a new one and it runs fine and the lights stopped flashing,however it is still lit up constantly,does this mean another fault? it drives fine now

 

anyone? does it just need clearing now the faults been repaired? i know bugger all about fiestas

 

yeah usually: management light comes on, fault code reader diagnoses the fault, fix fault, clear fault codes.

if the management light comes back on then there will be another fault but usually the initial fault code read should pick up all the faults in the system?

hth.

 

disconnect the negative battery lead for 15 mins and branch onto the postive once will reset the fault codes

 

what do you mean by branch on the pos?

 

tap negative lead onto postive lead
