0122 Refer to the electrical circuit diagrams and check the power and ground connections to the ABS module. Using the manufacturer approved diagnostic system, complete a CAN network integrity test. Refer to the electrical circuit diagrams and check the CAN network between the ABS Module and Transmission Control Module The same test goes for each of the module communication codes. Normally these are a result of a shorted can communication somewhere in the circuit or inside any of the modules on this circuit, The C1A codes indicate a faulty EEPROM inside the terrain response rotary control module. This needs to be replaced and programmed prior to diagnosing the CAN codes.
