DIAGNOSIS AND TESTING (Continued)
Contactor Box Current Sensors
Diagnostic Trouble Code (DTC) Definition
The following DTC relates to the main and
auxiliary current sensors in the contactor box:
• DTC C1835 Current Sense Circuit Failure
— The battery control module (BCM) uses the
main current sensor to monitor the current
flowing through the main high-voltage bus
during the drive cycle and the auxiliary
current sensor to monitor the current flowing
through the auxiliary high-voltage bus during
the charge and drive cycles. The BCM sets
DTC C1835 if the main or auxiliary current
sensors fall out of range at any time. Out of
range is considered to be below 5 milliamps
or above 45 milliamps. The BCM also sets
DTC C1835 for the main current sensor if the
current estimate from the traction inverter
module (TIM) is 50 amps greater than the
current reading from the main current sensor.
