Traction and ABS lights help
 
So I'm down in Florida picking up a 2002 impala with 40,000 on it. I have no way to read codes. The traction control is off and the ABS light is on. When you start the car it says service traction control system.

Can anyone make an educated guess for me?

Thanks
Ken

could be:
the wiring harness
bad sensor (requires wheel hub replacement. since the sensor is not a replaceable part)



Bad sensor is a very common issue replacement is $80 to $150 depending on where you go.

Likely a bad sensor as mentioned. The traction control and abs are pretty much one in the same and use the same sensors to do their business.

It's completely safe to drive without the TCS or ABS.

Thanks. I can change hubs. If I use the scan tool when I get home will it tell me which hub?

My car has the same lights on. I took it to pep boys and they said I should take it to the dealer. They couldn't pinpoint the exact cause but scanned the codes and came up with:

c1216 ebcm, c1218 abs pump motor, c1221 If wheel speed sensor, c1222rf wheel speed sensor, c1226 rf wheel speed sensor, c1233 rf wheel speed sensor, c1245 low tire pressure....basically they said it may be a wiring issue or possible bad ebcm.

I honestly haven't fixed it's been about 5 months. It drives fine. The lights are annoying though.

Pretty much the same thing as 05LS And, yeah the lights and bells are annoying..anyway to override that?

None of that maybe the issue have you tried filling up the tires? and reseting it?

Assuming you still have the useful factory radio installed

1. Turn Ignition on and turn radio off Very important not to start the engine or this will not work.
2. Press and hold DISPLAY on the radio until SETTINGS is displayed.
3. Use SEEK , scroll until TIRE MON appears
4. Press Prev or Next till RESET is displayed.
5. Press SEEK button.
6 Exit





Traction control is just electronic controlled differential .


off is not locked( depending on manufacture setting)
on limited slip variable electronic controlled.

ABS prevents the breaks from locking up when you press them hard. This helps the car stop faster.


both traction control & ABS use the sensor(s).

Yes it will. If it does not you could just search the code on the internet.

I also had this same problem. If the pump and ebcm codes show up your ignition switch is likely at fault. I just hope the faulty ignition switch didn't take out your ebcm (brake control module) and abs pump. It did on mine. Common problem. When an ignition switch starts to fail it send spikes of voltage to various components and can burn them up. I would get it fixed ASAP before it creates big problems like I had.

To be honest it sounds like you guys are already too late and your ebcm is done for.

A local dealer replaced my EBCM, Ignition switch, and cylinder for a wopping $1,250. It's not something you can do yourself. You could but the ebcm is $500-700 alone, ignition switch and cylinder is around $100, along with a "dealer only" abs brake setup of about $100 or so. You can only bleed the abs system of brake fluid with a tech 2 scanner.

Edit: If you have abs sensor codes along WITH the abs pump and ebcm do NOT just go and replace hubs. The fault is likely at the ebcm, pump, or ignition switch. You WILL be replacing the wrong parts and wasting money. When an EBCM fails and throws codes, so will your abs sensors.

Read codes when I came home today and the only code I got was 0420 for the cat/02 sensor. I assume that I need to go somewhere and have codes read now for the traction and ABS. I'll try my local autozone first I guess. I did the scan with the car not running and the ign on. Any other suggestions to pull codes?

auntjemima 04-09-2013 09:44 AM

alot of readers wont pick up abs or body codes.

GTXKen 04-09-2013 12:25 PM

Just got back from Autozone, DS front hub sensor

g25racer 04-09-2013 10:33 PM

^^ Check wires and connector first.

ouch 1400 or so to fix that

If you do not mind how much was the impala?

g25racer 04-09-2013 10:53 PM

^^ Huh? 1400 to fix what?

P0420

$1400 is for a factory replacement , replacement cost is depending on the state emissions requirements. Some states require factory emissions equipment, other wise it's automatic fail.
