DIAGNOSIS AND TESTING
Auxiliary Contactor Relay Control
Diagnostic Trouble Code (DTC) Definition
The following DTC relates to the control of the
auxiliary contactor relay:
• DTC C1862 Contactor Circuit Failure
— The interface adapter assembly (IAA) module
controls the auxiliary contactor relay to
provide high-voltage power to the high-voltage
auxiliary loads. The IAA module closes the
auxiliary contactor relay when the ignition key
is turned to the ON position and monitors its
status through a feedback line from the
contactor box. The IAA module sets DTC
C1862 if it detects the auxiliary contactor
relay open when it should be closed and
closed when it should be open.
