SOURCE: check engine light comes on
Do you hear the air pump run when you start the car? No? Check the A.I.R. pump fuse in the under hood fusebox. if it is blown then you probably need a new air pump motor. If the fuse is not blown then the relay could be the culprit. if you can hear the pump running when you start it the engine then you probably just have some wiring issues from the relay to the ecm it can still work ok but fail the resistance test that the computer runs randomly. Give some more info and I'll help you through this.
Good luck.

SOURCE: auto scanner code 1698
The P1698 code means that no digital data is being received by the powertrain controller from the transmission control module, located on the right inner fender. The manual says to check the CCD bus wires between the module and the rest of the system using the Chrysler diagnostic readout box. But if you don't have one then I think you can do the same thing by measuring for continuity (near 0 resistance) between pin 4 of its plug and pin 11 of the data link plug under the dash or pin 59 of the powertrain controller plug.
Then check the resistance between pin 43 if its plug and pin 3 of the data link connector or pin 60 of the powertrain controller plug. The powertrain controller is on the opposite side of the engine compartment on the left inner fender. These module plugs are held in place by a bolt. If the continuity between the transmission and the powertrain CCD wires checks to be ok, then according to the manual the trans controller should be replaced.
That is my analysis of what you report. You may have been told to replace the body control module erroneously because the code for that is P1695. If the independent garage was using the check engine light as its diagnostic methodology those problems both give a code 66, so they may guessed that it was the body module as being the faulty one. Problems with starting and with gauges are often related to this data bus communication system so all your issues seem to point this way. You might also, when checking the wires, also verify that they are not shorted to ground.
