C1763 is a fault in the RR suspension position sensor. You should also have a SERVICE RIDE CONTROL message. The sensor mechanism is a box bolted to the body with a link connected to the control arm. I would remove and install the chassis electrical connector several times to wipe the contacts clean and check the wiring. Clear the code and test drive. P0503 VSS circuit. The vehicle speed sensor is located on the outboard top side of the RH front axle shaft housing (part of the transmission case). Again, cycle the connector a few times and check the wiring. Fuel level sensor is part of the pump assembly inside the tank. "U" codes are most frequently set as false codes possibly due to one or more modules missing a clock cycle during start. I always clear them and forget them. DIM is the Dash Integration Module. Jim Drive your car. Use your cell phone. CHOOSE ONE ! Link to comment Share on other sites More sharing options...
Cadillac Jim Posted July 26, 2006 Report Share Posted July 26, 2006 DIM == Driver Inflator Module, the module that sets off the air bag in the steering wheel. The VSS is on the top of the right half-shaft. You can see it by turning the steering all the way to the left and looking behind the front wheel. Reach up and wiggle the connector and push it on. The surge tank vent hose is above and in front of the VSS and if you vent coolant and it dries on the VSS connector, the antifreeze can cause an intermittent VSS failure. If it continues, or comes and goes, you may have a cooling system problem. Position Sensors are on each rear wheel and they support the CVRSS and load leveling. This strange menagerie of codes looks like a battery cable problem to me. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.
