CEL and er 55
So today, while I was pulling people out of snowdrifts, my CEL and ABS lights came on at one point. Also, a weird er 55 thing flashed in the place where the mileage is shown (on the speedometer). What is that er 55?? I've turned off the car and restarted, the ABS light and the er 55 went off but the CEL and Cruise lights stayed on (cruise kept flashing). The car behaved normally though. I've disconnected the battery to reset the CEL, and all is good now. I just can't stop thinking about the er 55, never seen that before. What is it??

Another Subaru site says it's error ss [speed sensor]. They said it happens when you spin the tires and confuse the Computer/ABS system, it goes away after a few miles once it figures out everything is ok.

That explains it perfectly! Thanks!

Ok, problem is back :3: Last weekend I was towing my 67 Bug down the interstate (it's gutted, weighs less than 1000lbs, I have towed it before with no problems). After about 15-20 minutes of constant speed (70mph) my ABS light came on and the er 55 showed up again. I have pulled over, restarted and both went away. Few minutes later, they both came back on. What the ****? After I got home, I've checked the codes (key on, lights on-off, trip meter 4 times...). Got C0105, C0108, C0115 codes. Now, I've found out about this self checking method a few weeks ago (prior) and had the same codes come up without any issues. So, makes me think that they got stored after the first time (the first post) in October, when I was pulling people out of snow drifts. Any way to reset the ABS to clear the codes without going to the dealer?

Btw, the light seems to come on at highway speeds (60+) only, after about 10-15 minutes of constant speed. Goes away on restart. I've had it come on yesterday again (not towing).

C0105 Abnormal RR wheel speed sensor signal

C0108 abnormal FL wheel speed sensor signal

C0115 Abnormal speed sensor signal (any one of four)

The ERss is a LAN communications problem related to the wheel speed sensors.

It looks as if the ABS is losing the signals from one or more of the wheel speed sensors. These are essentially magnetic pickups, but I wonder if bad connector contacts, or accumulated mud or ice could cause weaker signals which, at high speed, become low enough (under noise) to trigger the codes. Might be worthwhile to pull the wheels and check/clean around the sensors and the connectors.

I'll try that tomorrow, need to inspect my brakes anyways. It is possible that something got dirty under there, with all the wheeling and snow. I was just wondering if there was a DIY way to reset the ABS codes, so I can see if the problem gets fixed or not. Will disconnecting the battery clear them?

I'm not certain if a battery disconnect and wait, will clear the codes, but I guess it can't hurt trying (although some user settings, such as the radio, might be lost.)

Perhaps others can confirm if this works, particularly on the ABS system.

I've checked the brakes a few days ago and have also pulled the ABS wheels sensors out and cleaned them out. They weren't really dirty though, just some minor dust. I've disconnected the battery and let it sit for about an hour. The ABS light no longer comes on, everything works fine, but the codes still remains when I go to pull them. I think I just need to run to a shop to get it reset. Stupid sensor dealies... I swear, these new cars are just oversensitive to just about anything :3:
