414-03A-62 414-03A-62 High Voltage/Traction Battery
DIAGNOSIS AND TESTING (Continued)
PINPOINT TEST Q: DTC C1861 PRNDL INPUT #4 CIRCUIT FAILURE
TEST STEP ACTION TO TAKE
No = REPAIR the Y wire.
WARNING: The traction battery contains high-voltage
components and wiring. High-voltage insulated safety gloves and face
shield must be worn when performing the following steps. Failure to
follow this warning may result in severe personal injury or death.
•
Connect 104-Pin Breakout Box (BOB) to traction battery support tray
in-line C1939F and in-line C1939M using Traction Battery Low-Voltage
Service Cord.
•
With key OFF, disconnect BCM C1987 and measure the resistance of the
Y wire between pin 18 on BCM C1987 and BOB pin 52.
•
Is the resistance less than 5 ohms?
Q4 CHECK FOR INTERMITTENT CONCERN(S)
•
With key OFF, reconnect DTR sensor C4996 and BCM C1987. Yes = REPLACE the BCM.
•
Perform the on-demand self-test for the BCM. No = System OK. CHECK wiring
•
Does DTC C1861 PRNDL Input #4 Circuit Failure occur?
for intermittent connections.
PINPOINT TEST R: DTC C1863 EXTERNAL CHARGING FAULT
TEST STEP ACTION TO TAKE
R1 CHECK CHARGER CORD INPUT STATUS
NOTE: Verify the power control station (PCS) charger cord is not plugged
Yes = GO to R2.
into the charger inlet before performing this test step.
•
With key ON, monitor BCM PID CHGCORD.
•
Does the CHGCORD PID indicate IN?
No = System OK. CHECK wiring
for intermittent connections.
R2 CHECK CHARGER INLET CONNECTOR
•
With key OFF, disconnect in-line C1969 (located on the chassis next to Yes = GO to R3.

R3 CHECK CHARGER CORD INPUT STATUS CIRCUIT FOR
SHORT TO GROUND
•
With key OFF, measure the resistance between the Y wire on in-line Yes = REPLACE the BCM.
C1969M and ground.
•
Is the resistance greater than 10,000 ohms?
No = GO to R4.
R4 CHECK TRACTION INVERTER MODULE (TIM) FOR SHORT
TO GROUND
•
With key OFF, disconnect TIM C4998 and measure the resistance Yes = REPLACE the TIM. REFER
between the Y wire on in-line C1969M and ground. to Section 303-14.
•
Is the resistance greater than 10,000 ohms?
No = GO to R5.
R5 CHECK CIRCUIT 3404 (Y) (OUTSIDE TRACTION BATTERY
SUPPORT TRAY) FOR SHORT TO GROUND
•
With key OFF, disconnect in-line C1939 on the traction battery support Yes = GO to R6.
tray and measure the resistance between the Y wire on in-line C1969M
and ground.
•
Is the resistance greater than 10,000 ohms?
No = REPAIR the Y wire (outside
the traction battery support
tray).
R6 CHECK CIRCUIT 3404 (Y) (INSIDE TRACTION BATTERY
SUPPORT TRAY) FOR SHORT TO GROUND
