ABS & Parking Brake Lights On

[G1en]

Advice Needed

Just been to a rolling road for a dyno run as part of a new championship i am doing this year.

On drive back home noticed the ABS and Parking Brake warning lights are on.

 

I have disconected battery and reconnected

Checked with my OBD reader - No codes stored or pending

I have the module wired in that permanently disables/ re-enables TC and SC this is still working fine and has no impact on the ABS light switching it off/on

Checked alll relevant fuses (i think) and all seem ok

Checked behind brake pedal and both switches that connect and all seems ok

took it for a drive after turning off/on and disconnecting battery and still on (stays on from ignition)

 

Only thing left is checking abs sensors but would this throw a code? How will i know which one might be faulty without swapping the lot?

On the rolling road it was slipping a lot and i am wondering if that has caused the lights, I dont know if they were on straight after session or not, there was no mapping or anything involved, it was just a power run (or 3) to determine the power of the car then it was weighed.

 

cheers

Sorted it.

Because I have the module wired in (CS Burnout Mod or whatever you want to call it) that disables TC and SC I had to disable that and then drive for a period co the whole system could reset. just turning it off/on and starting car wasn't enough. And I had been driving back from dyno with it on which must bypass the system so the ABS light didn't clear. I thought it highly unlikely there would be a fault if nothing was messed with, its common that lights throw up after a rolling road session as i assume rear wheels going 150mph whilst front wheels are stationary throws the system into meltdown. My OBD reader also doesn't read ABS/SRS faults/codes just the main Engine ECU so it would never have detected anything anyhow. Something for others to bear in mind. 

Hope that makes sense to everyone (but prob doesn't lol)
