Grand Caravan 2011 My ABS light, parking brake light, and check engine light are all illuminated, my speedometer is broken, and my 4x4 just blinks and refuses to activate. The code I get was p0500, which indicates that there is no speed sensor signal. I've tried replacing the back diff sensor, the trans sensor, and both abs speed sensors with no success. My mechanic has also disconnected the abs mod. And both batteries to attempt a reset with no success. He claims I require a new ABS module. Any suggestions?
Thanks
