Truck has run fine so far. It is an auto with 52000 miles on it. Went to start it today and the gauges, speedo, tack, and overhead coumpas quit working. The check engine light , air bag light and ABS lights are on. Truck runs fine the little bit I drove it. Checked for codes and it is setting P1698,P1687,P1694. Any information as to what might be wrong would be greatly appreciated.

Several things........could be one of the modules has "locked up" , stopping the communication on the CCD Bus, or ...I think one guy on here had a shorted crank sensor! Try unplugging it real quick and see if the guages and all come back.
