Inspection and Verification
•
DTC C1862 Contactor Circuit Failure
Refer to
— The battery control module (BCM) performs a
battery heater test during on-demand self-test
with the negative contactor relay closed and
then open. Under normal conditions, the heater
test will pass with the negative contactor relay
closed and fail when it is opened. The BCM
sets DTC C1862 if the heater test passes with
the negative contactor relay closed and then
passes with the negative contactor relay open.
This indicates the negative contactor relay is
stuck closed. Additionally, the BCM sets
DTC C1862 if the traction inverter module
(TIM) detects a welded main contactor relay
and sends the BCM a disable charging
message. The BCM also sets DTC C1862
before entering current mode, voltage mode,
and during voltage mode each time before
charging if there is current flow through the
contactor box auxiliary current sensor while
the BCM asserts the negative bus open signal
and enables the charger with 72% duty cycle
in current mode.
