Hey there, my mother in law has a 2010 jeep liberty 4x4 with 117k miles on it. She asked me to take a look at it. With it running it has the following lights:
ABS
ESP
BAS
Serv 4wd
Brake
And check engine
Speedo is also dead, no vehicle speed reported on live data from odbII.
Upon reading the DTC codes I come up with:
U0121
U1120
U1110
Not sure what to check, I have disconnected all modules and reseated them under the hood, went ahead and replaced input and output speed sensors on the transmission. Wiring and sensors to all 4 wheel speed sensors seem fine. Not sure what to look at next. She says when she drives it usually the lights stay on and speedo does not work on short trips, however, on longer trips (20-30 mins) she says the speedo will come alive and all lights will turn off other than check engine. I do not have a high tech scan tool, I have an BlueDriver just FYI. Any ideas?
