Brake Lights

1271 3
I have a 2008 Jeep Commander 3.7. Today the parking brake, ABS, ESP/BAS, and the Traction control lights all came on at the same time as shown in the picture. Anyone know what causes this and what the fix might be? I read another forum that said this might be a wheel speed sensor? Also when engaging the parking brake the Parking brake light does not come on.

There are no codes being thrown.

Correction. I took it to Autozone and their scanner can check ABS code and it is throwing C2200 ABS Module Internal... Fantastic!

I did flush and bleed the brake lines about a week ago.

Thanks!

You will get that if you have the key on and manually spin one of the wheels while servicing the vehicle. You can reset the codes and make it go away when that happens.
The parking brake has a fairly large switch inside the console that gets triggered by the lever. You can pull the console apart and clean the switch.
Are you low on brake fluid? That Brake alarm is not just for the parking brake, it's for any possible problem.

I also had this occur to me a few weeks ago, same code, cause unknown. I had checked everything out, wheel speed sensors, wiring etc to no avail. In my case I could reset the code/erase and it would come back after moving a short distance. It eventually cleared itself after so many successful run cycles or miles. don't know which, but it has stayed off for at least 2 weeks since clearing itself. Would recommend you live with it for a while before sinking a lot of $ into it. The ABS control module is in the $600-900 range new.

Update: I had this happen again, but have seemed to narrow it down to a speed differential between the rear wheels on aggressive acceleration around a corner. When I accelerate really hard, enough to activate the ESP when turning a corner I can hear the inside tire screech (like a 1 wheel peal) more than the outer tire before the traction control kicks in. In my opinion this is probably caused by the wheel speed sensors reading a significant differential between the two, throwing the lights. After about 5 short normal trips, the dash lights reset themselves. Same error code as what you mentioned.


Maybe someone can confirm this observation, I would expect that it can come up when offroading if you keep the traction control activated, a slightly prolonged one wheel traction loss, might cause the same. Thoughts?
