The BAS,ABS, Traction Control, and service 4x4 lights are all on. I scanned the computer and the LR speed sensor was not picking up a signal. I checked all the fuses,replaced the speed sensor,checked the continuity of the wires from the speed sensors to the ABS computer and still have all the lights on. I also notice the cruise control is not working.. Any suggestions?

Check your wheel speed sensor. Could just be unplugged. |

Ok, first is would switch the rear sensors to verify that the new sensor is good. Then, my next suggestion would be to check the tone wheel. There is a slim possibility that there is foreign debris or that the wheel is damaged. To view it like this, you will either have to disassemble the parking brake shoes or option 2..... Open the diff cover, remove the cross shaft pin, push the axle in, and remove the C clip.   M |

I did switch the sensors and still picking up 0 mph and 0 rpms from the Left rear sensor- I also made sure the Left "was" the left and the "right" was the right as i have encountered them being reversed with chrysler vehicles before--mainly Caravans-- I checked the Tone ring and it was clean and not damaged as close as i could see. Is there some type of ohm test for the sensors? I still think it might be a problem right in the ABS computer---Can it be tested? Thanks for your help

Sensor should be producing a voltage readng while spinning the wheel fast enough by hand if it is good I believe. You sure the wiring to the sensor is good? |
