Yes they can but unlikely-more likely a bad over voltage relay(powers up idle speed computer) or wire harness-your vehicle is probably a hfm type fuel injection they changed from lh that year. find out if it is lh check the fuses in the base module located in the passenger side of the engine compartment under a cover held in by 4mm allen head bolts-alot of times these control units have intermittent contact with there connectors. asr stands for acceleration slip regulation-both isc and asr communicate via can system to monitor throttle position- ea isc cc-idle speed cruise control and electronic actuater(throttle)-hopefully i have helped

Suspect idle control motor, although mass air flow sensor problems have sometimes been related to idle surge. Have pcm codes pulled for further diagnosis.

The asr light is on and the car does not

the o2 senser would not cause the a.s.r. light to come on-there is only 2 things that the engine module and the a.s.r. module have in common. 1 is the e.a. actuater(throttle) and 2 is the base module. most likley either your acuater has to be resynchronized or the actuater itself is bad. have codes pulled from your h.f.m.,a.s.r.,e.a-i.s.c.-c.c modules and see what the codes say. You will probably find that they say e.a. actuater module is defective. the pig tail connecters go bad and they need to be replaced just be glad you do not have a 600 series because they cost about 1200 a piece and the v12 have 2 of them. If it is defective and you cannot resynchronize it there is a company that rebuilds them for about 1/3 the cost of a new one- good luck

The ABS ,BAS& ASR lights keep coming up


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
