My 2005 S40 was driving perfect yesterday. Its been drizzling today and about 27 degrees. I was heading to the airport and about 1 mile from home the check engine and skid lights flashed on and off a couple of times. I decided to turn the car around because it was acting like it was going to shut off. I got stopped at a red light and the engine shut off. The lights and everything electrical continue to work but the car would not start. I made several attempts but was receiving a "ANTI-SKID SERVICE REQUIRED" message. I am still not able to get the car started.

 

Each time I've read of this happening it was because of low voltage. Either a bad alternator not charging the battery or a bad battery or battery connections. Check the voltage to the battery to make sure you have 12 volts.

Also, when you say it would not start do you mean the engine would crank over but not start? Or do you mean the engine would not even crank over? Crank means the starter is physically rotating the engine. Start is what happens after cranking. Just helps folks give you better guesses.

 

This morning the car cranked a few times and then shut off so I replaced the battery. The car started for a second with the new battery and then shut off. The car will no longer crank.

 

Check the battery cables. I have seen cables corroded UNDER the insulation such that they could not carry the amperage needed to crank the engine. Try wiggling the battery cables while someone turns the ignition key to crank the engine.

I would also clean the cable ends and give them a good look over. Then I'd use a multimeter and check continuity and resistance in the cable. Then I'd check the voltage reaching the starter, both before and during cranking.

Let us know what you find?

 

Sunday morning I tried again and it started right away. I let run for a while and there seemed to be no problems so I drove it around the block. It seems to be running fine now.

 

My 2006 XC90 V8 AWD has occasionally (like once or twice a month) displayed the "Anti-skid service required" message when running in ordinary road conditions. Following the owner's manual instructions, I usually turn off the engine and start it again, and the message disapears for weeks. I've heard it might be caused by some bad contact in sensors and wires. Can anyone give me a clue on where to check for bad contacts?

 

The battery did not end up being the fix. About a month after I changed the battery, the car would not start and "anti-service required" showed up again. I had the car towed to my mechanic who works on Volvo's and BMW's and he said the engine computer was bad and would need to be replaced by the dealership. $2000 for the repair!!!

 

I would find another mechanic. The last time someone told me that it ended up being a fuel pump. Anyways, seek another opinion. Engine computers rarely fail.

 

I had this happen to my 2010 S40 T5 R-Design AWD. First few times it happened I turned the car on and off a few times and it went away. Then when I finally took it to the dealer to get the problem addressed they told me it was a bad steering module or something like that. They replaced the module. Didn't charge me labor but cost me $350 for the part. Fast forward a year or so and it started to occur again. I took it to another dealership who hooked it up to the diagnostic machine I guess after resetting the computer and they couldn't get it to happen again. Hasn't happened since then which was probably over 6 months now. I would hesitate to have the entire computer replaced for $2k.

 

the message is generated from sensor on brake assembly.

 

I have a 2008 XC90 Sport. I have tried everything to reset the messages. I currently have the anti-skid service required and time for maintenance messages. The anti-skid message has been on for almost 2+ years and came on after my first break change. I can not seem reset these messages and everytime I try to reset I get these codes. 167, 124, 045. Does anyone know what these codes mean? Help!

 

your sensor on your brake assembly is either not installed correctly or broken off. It goes on the back of the rotor on the strut.only one wire going down to it easy to identify.

 

Thanks for your help! Is there a part number for this in the case that it is broken off?

 

Is the sensor on the hydraulics brake assembly inside the engine compartment or in the brake assembly at the wheels?
