Hello,

Just bought a 98 s70 GLT a few days ago so i am very new to volvos. Howeve not so new to cars since i have a stage 3 wrx that i have been messing with for years. Just a few quick questions and looking for some enlightment:
1. The car has traction control button, how do i activiate it, how do i de-activite it? pressing it and holding it down for several seconds seems to have no effect what so ever. no instrament light lights up or turns off.
2. the car has ABS, but it still locks up under heavy breaking. No ABS light and the fuse is still good, any ideas?
3. the speedo work sometimes and sometimes not. just like another guy on this forum states, half of the time it work after turning the car on/off again.
4. i just noticed this tonight while driving...the circulation button (u know the one next to the AC button) and the AC on button both flashes together several times. Is this some type of trouble code? no check engine light what so ever.

Thank you for any input ahead of time!

 

1. Traction control is on unless the driver disengages it. This is from the Owner's Manual.

2 & 3. Check this site as the problems you are having in 1, 2 & 3 seem to be related to the ABS module. Tracs is operated by the ABS.

4. The ECC is telling you that there are fault codes stored. Have the codes read and post here for more info if necessary.

 

Bill, thank you very much for your help and feedback.
When I turn the ignition key to the I position (on, but not fully started) there are of course several lights like low coolant light, check engine light, SRS, etc however there are no ABS light and Trac. Does this straight up mean my GLT doesn't come with ABS? I checked out the manual and expected to see the ABS light but that square shows nothing but black.
The check engine light came on today and i pulled the code to be 500 which means either a speed sensor or speed light? which explains why my speedometer works only sometimes.

Is it normal to have so much eletrical problems wrong with a 9 years old volvo?

Regards

 

Sounds like someone removed the ABS and Tracs light bulb because they didn't want to replace the ABS module.
I would send it to the link above and also try to replace the bulbs as well.

Yes the lights on the A/C panel flashing means there is a code in the system.

Does the recirc function work normally?

 

The recirc does work properly .

My main issue with the car now is with the 500 code (speed sensor). Can anyone please provide some feed back on this issue? Is this an indication of a bad speed sensor? in subarus it is very easy to replace the speed sensor, however after talking to the volvo parts department they said i need 2 sensors, one in the bell housing another one in the tranny. is this true? thank you ahead for all of the help!

 

Code 500 where did it come from? Which system?

 

Went to autozone and had the OBDII code pulled. there is a print out and said code 500.

 

Speed sensor is most likely cause of the ABS and Tracs issues also.
