A class 2 serial data bus is a communication network between control modules on the vehicle ! It is not a single module . The PCM/ECM - engine computer , ABS - air bags , BCM or in the case of your Caddy three computers make up the BCM , DIM ,RIM and the IPM . Your best bet would be to take your vehicle to a qualified repair shop .

Here's a link to codes.

Try pulling codes
To pull codes, put the key to on position without starting and of the three buttons on the right of speedo cluster hold down the right and left button for a few minutes until the speedo screen changes. Alternately you can get the codes pulled from autozone etc. for free.

If you are getting IPM b0429, it could be a control module. Google "b0429 cadillac forums" for more information.

check coolant level. is it low? refill and remove air from system.
