Simon_CSK Posted July 29, 2018 Share Posted July 29, 2018 At last I have finally got my Disco on a computer so now can someone help me interpret the results? Faults as follow: 01 Manifold pressure circuitt fault. Logged Low 02 Driver demand supply fault. Logged Low 03 Ambient Pressure circuit fault Logged Low 04 Manifold pressure circuitt fault. Logged High 05 Inlet air temp circuit fault. Logged High 06 Ambient air temp circuit. Logged High 07 Ambient air temp circuit fault. Currently Active 08 High speed crank sync lost fault. Logged 09 Coolant temp circuit fault. Logged 10 Fuel temp circuit fault. Logged 11 Driver demand 3 fault. Currently Active 12 Driver demand 1 out of range fault. Logged 13 Driver demand 2 out of range fault. Logged 14 Faults detected with driver demand. Logged 15 Road speed missing fault. Logged 16 Can error fault. Currently Logged 17 Faults decected with driver demand. Logged 18 Topside switch failed post injection. Logged 19 Injector 3 peak charge short. Logged. I don't have a clue what any of that means. If asked to guess I would point to injector 3 Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted July 29, 2018 Share Posted July 29, 2018 With that many faults I would go straight for an earthing problem, it could give you all sorts of issues. Quote Link to comment Share on other sites More sharing options...

If asked to guess I would point to injector 3 out of all those codes, the one that jumps out as being the biggest issue is the topside switch failed, this can lead to a dead / dying ecu from IIRC one of the components on the board dying, clear those codes & see what ones come back, what are you using to read the codes?

Before the computer used the spares cannon and replaced the ECU and the BCU and the result was still the same. i.e. would only idle and not rev We cleared the codes and it came back with 01 Ambient air temp circuit fault. Logged High 02 Ambient air temp circuit fault. Currently Active 03 Driver demand 3 fault. Currently Active. 04 Faults detected with driver demand. Logged 05 Faults detected with driver demand. Currently Active I don't know what the diagnosis gear was. All I know is that it was expensive. Quote Link to comment Share on other sites More sharing options...

Topside switch relates to the injector capacitors, id have to dig through my notes to give a verbatum answer, the ECU that you fitted, what was the part number? what was the old ecu part number? Ambient air temp id ignore for now, Driver demand faults relate to the throttle pedal, Did you check what the live data was displaying in regards to the throttle pedal voltages? I cant remember if the parts cannon had fitted a throttle pedal ? Quote Link to comment Share on other sites More sharing options...
Simon_CSK Posted July 30, 2018 Author Share Posted July 30, 2018 Te parts cannon changed the throttle pedal the ECU and the BCU. I bought a new engine bay wirning loom and an injector loom. Quote Link to comment Share on other sites More sharing options...
