DIAGNOSIS AND TESTING (Continued)
PINPOINT TEST B: VEHICLE WILL NOT START (POWER RESET INDICATOR ILLUMINATED)
TEST STEP ACTION TO TAKE
B1 CHECK FOR ACTIVATED INERTIA SWITCH
•
Check the inertia switch. Yes = RESET the inertia switch.
•
Is the inertia switch activated?
No = GO to B2.
B2 CHECK INERTIA SWITCH
•
With key OFF, disconnect inertia switch C249 and measure the Yes = REPLACE the inertia
resistance between the LB/W wire terminal and W wire terminal on the switch.
inertia switch with the inertia switch in the deactivated (depressed)
position.
•
Is the resistance less than 5 ohms?
No = REPLACE the interface
adapter assembly (IAA)
module.

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 2.5 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.
