Inspection and Verification
•
DTC C1835 Current Sense Circuit Failure
Refer to Section 100-07 .
— 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.

PINPOINT TEST A: DTC C1835 CURRENT SENSE CIRCUIT FAILURE
TEST STEP ACTION TO TAKE
A1 CHECK STATUS OF CONTACTOR BOX AUXILIARY CURRENT
SENSOR
•
With key ON, monitor battery control module (BCM) PID AUX SEN. Yes = GO to A2.
•
Does the AUX SEN PID indicate between 0.5 and 4.5 volts?
No = GO to A4.
A2 CHECK STATUS OF CONTACTOR BOX MAIN CURRENT
SENSOR
•
With key ON, monitor BCM PID MAINSEN. Yes = GO to A3.
