DIAGNOSIS AND TESTING (Continued)
PINPOINT TEST S: DTC C1861 PRNDL INPUT #4 CIRCUIT FAILURE
TEST STEP
ACTION TO TAKE
S1 CHECK STATUS OF DIGITAL TRANSMISSION RANGE (DTR)
SENSOR SIGNAL TR4 TO BATTERY CONTROL MODULE (BCM)
NOTE: Verify the transmission range selector lever is in the Park (P)
Yes =
System OK. CHECK wiring
position.
for intermittent connections.
•
With key ON, monitor BCM PID TRANSGR.
•
Does the TRANSGR PID indicate D6 PRK?
No =
GO to S2.
S2 CHECK CIRCUIT 3503 (Y) (OUTSIDE OF TRACTION BATTERY
SUPPORT TRAY) FOR OPEN
•
With key OFF, disconnect traction battery support tray in-line C1939 and Yes =
GO to S3.
connect 104-Pin Breakout Box (BOB) to in-line C1939M using Traction
Battery Low-Voltage Service Cord; do not connect Traction Battery
Low-Voltage Service Cord to in-line C1939F.
•
With key OFF, disconnect digital transmission range (DTR) sensor
No =
REPAIR the Y wire.
C4996 and measure the resistance of the Y wire between pin 6 on DTR
sensor C4996 and BOB pin 52.
•
Is the resistance less than 5 ohms?
S3 CHECK CIRCUIT 3503 (Y) (INSIDE OF TRACTION BATTERY
SUPPORT TRAY) FOR OPEN
•
Disconnect the BOB from in-line C1939M, remove the traction battery,
Yes =
GO to S4.
and connect Traction Battery High-Voltage Lockout and Diagnostic Tool
to the traction battery high-voltage two-pin C3994M.
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 carrying out 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?
S4 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 T: DTC C1863 EXTERNAL CHARGING FAULT
TEST STEP
ACTION TO TAKE
T1 CHECK CHARGER CORD INPUT STATUS
NOTE: Verify the power control station (PCS) charger cord is not plugged
Yes =
GO to T2.
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.
T2 CHECK CHARGER INLET CONNECTOR
•
With key OFF, disconnect in-line C1969 (located on the chassis next to
Yes =
the right headlamp inside the underhood compartment).
•
With key ON, monitor BCM PID CHGCORD.
No =
REPLACE the charger inlet
