Whenever this warning light or any other stays on in the dash it is indicating that the systems control module (or the system sensor in the case of lights like low oil pressure, door open indicators etc.) has detected a fault, it then disables the system (this applies to ABS,TCS, TCM, SRS, TPMS and BCM faults and others) as long as the light is on. You must now have the dealer hook up a special electronic diagnostic tool and "scan" the system for the fault code that is stored for the problem(s)

SOURCE: Warning Light on Mercedes ML270

Hi,

To my understanding:
BAS ESP - Electronic Stability Program (keeps you moving in the direction you intended the vehicle to go); probably a faulty brake switch or a bad brake sensor. You may want to reference this forum for additional insights;
ETS - Electronic Traction System (keeps you moving); would require an appropriate code reader to diagnose and pinpoint problem.Surprisingly, there has been some reports of defective brake pedal switch that activates this warning. You may lilkewise want to reference this forum for additional insights.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Check one of the fuses in the bonnet. There is most likely an electrical contact problem. You will need a fuse wire replacement

ABS + ESP lights staying on dashboard


wow no year car, now that is a challenge , no?
abs is first.
first- first are brakes.
abs stuck on key on and running full time right?
so check brakes for damage or worn out.
brake fluid level not falling? look yet? look when checking oil every time.
abs can not work on cars with bad brakes, (its not god like)
then check for ABS sensor damage and its wires. under car.
then scan the ABS. got errors, sure you do.
but what? you didnt scan it first.
or read the manual> RTM?
its only 4 bucks to read it.

You probably just need the ecu resetting, but there could be a need to set up a few more engine management features. Certain systems can loose callibration if power is diconnected for a period of time. Take it to your dealer

You need to scan ABS system and get some ideas.

The ABS ,BAS& ASR lights keep coming up


ABS--BAS

Most likely cause is the 'stop lamp switch'
It is a electric switch located on the brake pedal inside the car, about half way up on the brake pedal.
Pretty cheap too, I think the switch is only like $25 bucks.
2 connectors on the switch and then it turns out.
hope that helps

Can't find a BAS light in the manual , there is however a ABS light , which is a antilock brake system warning light . Check your tire presures before you check with the toyota service people.
ABS systems monitor the speed of the rotation of the tires , if one is low , the car sees it as a problem.
