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.
