Jeep Liberty 2.8 L Diesel ETC Light Flashing!

Hi, I own a 2007 2.8 L Liberty, and I my ETC ligth is flashing, and it wont stop. The car is running fine, and it has no power issues that i know. I think it started after driving through water, and i tried to dry the brakes while i was accelerating

Any help??

Thanks

Most likely a wet or failed speed or ABS sensor (maybe wire?). Give it some time to completely dry out & see if it goes away.

Post back & let us know if things came back to life.

Going to second the wheelspeed sensors; That or a damaged wheelspeed sensor wire.

I took the jeep to a Jeep dealership, they checked the engine codes. Then they reseted the computer.
No flashing ETC light no more. Car works fine.

I recommend you guys a device called kiwi from PLX, its a OBD II system for the iphone. Very cool. I actually ordered one today to avoid more trips to the dealership. It can check engine codes, RPMs, boost pressure, and much more.

PLX Devices Inc.

Thanks!

The jeep is designed to do this. It has an electronic throttle pedal, so if the ECU sees acceleration and braking at the same time, it will throw a code after enough of it. That's why you didn't have any real driveability problems.

UPDATE: ETC light started flashing again today. No check engine light. Car seems to work fine.
This is starting to make me think that there is something actually wrong in the car. I'm going to try to get an error code, from the dealership (but here in my country Jeep services are terrible...really for every car...).
Ideas? Please?

Thanks,
RR

Check for continuity on the wheelspeed sensor wire. The sensor itself rarely goes bad, but they usually get gunked up.

Check the wire's insulation for any signs of stretching or wear. Don't remember if the KJ's wheel speed sensors are integral with the wire or not, TJKJ probably knows though. Hopefully he'll chime in.

Thank you, T-birdJunkie, I'm going to try to find the wheelspeed sensor wire, and give it a check, before taking it to the dealership.

From what I've been told, an engine light is bad. A flashing engine light means go to the dealership immediately because something catastrophic is about to happen. I've never had a flashing light though.

I have a 2007, and it has the engine and the ETC light, but ONLY the ETC light is on and flashing.
Maybe your ETC light is dead, give it a check.

Good luck.
