Hi,
    Got a couple of leads for talking to my 06 Fabia VRS (BLT) now, one off ebay for about £7 and one off GenDan for £20.

Both seem to behave in the same way - After following a suggestion on here to turn the latency down in the advanced options of the com port it is on both leads work quite well.

However.

While they will communicate with:

03 - ABS Brakes
08 - Auto HVAC
09 - Cent Elec [1 fault; 01598 Drive battery voltage 07-10 signal too low - intermittent]
17 - Instruments [1 fault; 01314 Engine control module - 49-10 No comms - Intermittent]
19 - CAN Gateway
25 - Immobiliser [No faults found or DTCs not supported by controller or a comms error occured]
46  - Central Conv

the one I want to communicate with:

01 - Engine

Always gives an error "Too Many Communications Errors to Continue"

I've fiddled with com port latency - stuck the baud rate on 9600,4800,1200 and 300 still with no joy, it just will not communicate. Up in the top left corner, where for modules that communicate it usually says protocol: KWP1281, on 01-Engine it just says G71M=-1. Whatever that means. I've also disconnected the battery for 20 minutes then reconnected it and tried again, still no joy.

 

Outstanding fault codes are left in there for some time and have not been cleared. Suspect centelec fault may be from where I have cranked an old battery to the point where it has little juice left. battery since replaced.

Strangely, the OBD-II Bluetooth reader I have picks up data (which must be from the engine control module too?) absolutely fine.

Any ideas?

Reason behind me wanting to talk to the engine is I have an intermittent starting problem detailed in another post. http://www.briskoda.net/forums/topic/311386-2006-fabia-vrs-blt-intermittent-trouble-starting/

 

Thanks

Possible wiring loom fault? Low battery voltage?

Not 100 percent sure, just a suggestion.

Try getting a genuine cable plugged into the car.

My Golf had this.

 

Reran the cables, tried different dash clusters, different tools/cables, I think a different ECU too, but it still never worked. Just gave up on the car in the end (for other reasons too) and sold it to a we-buy-any-car type of place.

 

I did get it to work once, briefly, but by the time I'd restarted the car when my dad was ready to log some data, it had broken again.
