Diagnostic Trouble Code (DTC) Definition

The following DTCs relate to the interface adapter
assembly (IAA) module:

•

DTC B1342 ECU Is Defective
— The interface adapter assembly (IAA) module

carries out an internal self-test when the
ignition key is turned to the ON position. The
IAA module sets DTC B1342 if it does not
pass its self-test at key ON.
