Check P brake- Flashing brake lights???

[saxo265]

Afternoon all!,

Advice needed please. My T27 180 D-cat started flashing brake lights at 4am this morning! Car not used for 10days. Checked this morning, started first time, no apparent problem. Took for 20 mile run, no loss of power or lights until 19miles then 'check parking brake system then just before home VSC, pops up with ABS lit up.

Have searched here and it seems it may be EGR? but I have never seen anything with random brake lights flashing? Next door has just come and told me brake lights back on and staying on!!! have disconnected neg Battery terminal. Also noticed the cabin security light flickering too when engine running.

I know I will have to take it for code reading but why brake lights flashing/staying on when left standing?

Any ideas?

Ps. 1/2 mile from home & got pulled in by police for random vehicle check & tyres, all good thankfully & he did not see the dash lit up! 😂

EGR could set the fault lights but definitely not the Flashing brake and interior lights, sounds like there is a short somewhere, something as simple as a brake light switch could cause all of the symptoms mentioned, get the codes read and see what the car is unhappy about.

Thanks Lee, have ordered a reader, never used one before but will see how it goes and update 👍

Update! bought code reader, no codes stored, no freeze frame stored? Also showing, Since DTC's cleared this drive cycle, MIL status 'OFF' & everything else showing N/A? Misfire,fuel syst,cat monitor,EGR system etc.

I have not deleted anything just read the reader, Am I doing anything wrong???

The warnings lights have gone for now & it runs great but brake lights still staying on, discon. neg terminal again.

Am I right in thinking that the brake light switch is always powered when ignition off? ( ie.press peddle & lights on) If it could be the switch I would have a go at changing it but not as supple these days! as I am in my 70's but happy to give it a go! 😀 Any further advice would be appreciated, Cheers 👍

Hi, NA means the car hasn't been run long enough for data to be accumulated after reset. Sounds like it could be a circuit problem as you suggest..

Thanks Peter, everything ok this morning (no BL's on or MIL's) when re-connected apart from security light on when engine running? booked it in garage for further checks, just hope it is the BL switch. I also think I have a faulty scanner, the scroll button only works 1 in 5 times pressed! will get it exchanged.
