About the only ting they say here is fuses, wiring connection problem between ip, pcm and abs or a bad abs module. The modules on the high speed CAN are ignition switched. The high speed CAN is only on when the key is in the ON position.
The high speed CAN is not designed to operate under single point fault conditions. If either circuit is shorted to voltage or the high speed CAN data plus is shorted to ground, module-to-module and module-to-tester communication is marginal at best. The high speed CAN bus may remain operational when 1 of the 2 termination resistors are not present. If there are issues with the high speed CAN, there may be missing functionality and problems connecting with a diagnostic tool. On the CAN, there are 2 terminating modules which are composed of the PCM and the instrument cluster which are located at the far opposite ends of the CAN wiring. This is a toughy I really don't know what else to say.
