BAS/ASR light on 98 C250 TD

[randyhicky]

Was wondering could anyone help with this problem, the BAS/ASR light stays on all the time whilst the car is running/driving but this is the only warnin light that is illuminated, what are the possible causes of this and could this be limiting the power of the car??

check your battery, if the battery is failing it wont give enough voltage to the ECU's hence the warning lights. Get down to kwik fit or somewhere and get them to check it, or if you have a multimeter do it yourself.

Not sure if this one has a OVP relay, if ti has, it could be that but also as JIB

If after 1998 could be brake light switch

Sory forgot to say tested battery then charged it as it was low as the car had not been used in a year by previous owner then tried to reset it by turning the full lock one way then another but this did not work, sory im new to this lark what do the abriviations OVP and JIB Mean??

OVP = over voltage protection, JIB= me, my knick name. Sounds like you need a new battery.

Surly if the battery needed replaced there would be other warning lights? are there any senors in the system that may need replaced?

Though the ABS runs from the engine, a low voltage at the start can trigger the lamp on.

With the battery the voltage with headlamps on must be over 12 volt, once it drops to 11.75 this will put the BAS/ABS lamps on.

the running voltage on the car must be 13.8 volt
