Inspection and Verification
•
DTC C1862 Contactor Circuit Failure
Refer to Section 100-07 .
— The BCM 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.
This indicates the negative contactor relay is
stuck closed. The BCM also sets DTC C1862
if the traction inverter module (TIM) detects a
welded main contactor relay and sends the
BCM a disable charging message.
